The western United States this century is facing a greatly heightened risk of heavy rains inundating areas that were recently scarred by wildfires, new research warns.
Such events can cause significant destruction, including debris flows, mudslides, and flash floods, because the denuded landscape cannot easily contain the drenching moisture.
A new study finds that, if society emits heat-trapping greenhouse gases at a high rate, the number of times that an extreme fire event is likely to be followed within one year by an extreme rainfall event will increase by more than eight times in the Pacific Northwest by the end of the century. It will more than double in California.
Overall, more than 90% of extreme fire events in the three regions that the research team focused on — which included Colorado along with California and the Pacific Northwest — will be followed by at least three extreme rainfalls within five years.
The study authors, including scientists at the National Center for Atmospheric Research, or NCAR, used advanced computer models of past and future climate, as well as an index of weather variables that contribute to wildfire risk, to reach their results.
Lead author Danielle Touma, who did much of the research at the University of California, Santa Barbara, before coming to NCAR, noted that previous research has shown that both wildfires and extreme rainfall will increase in the West with climate change. However, the increased frequency of extreme rainfall-after-fire events came as a surprise.
“It’s very concerning, given the destruction that comes with these kinds of events,” Touma said. “Clearly we need to understand the risks better, as this creates a major threat to people and infrastructure.”
The study is being published this week in Science Advances. Funding came primarily from the U.S. National Science Foundation, which is NCAR’s sponsor, and the Department of Energy.
Researchers from the University of California, Santa Barbara; the University of California, Los Angeles; the Nature Conservancy of California; and Washington State University contributed to the study.
Fires and rain on the rise
Heavy rainfall on burned areas is often hard to predict, but it can have devastating impacts. In 2018, debris flows in Montecito, California, caused by a brief and intense rainfall over an area that had burned just a month earlier, left 23 people dead and caused widespread property damage.
Torrential rains in Colorado’s Glenwood Canyon last year triggered a massive mudslide in a recently burned area, stranding more than 100 people and closing a portion of I-70 in the canyon for weeks.
Following a fire, the risk of debris flows persists for 3-5 years, and the risk of flash floods for 5-8 years, because of the time needed for ground cover and fine roots to recover followed by the regrowth of vegetation.
To study the frequency of extreme rainfall events after extreme wildfires in a warming world, Touma and her co-authors turned to an ensemble of simulations by a number of climate and weather models, including the NCAR-based Community Earth System Model, a powerful computer model that enabled them to project likely changes in climate in the western United States.
The results indicated that, by the end of the century, there will be a doubling or more of weather conditions that lead to the risk of extreme wildfires throughout much of the West, with some regions experiencing greatly elevated extreme wildfire risk within the next few decades. In addition, the climate models showed a pronounced increase in extreme rainfall events.
The researchers then looked at the number of cases in which extreme rainfall is likely to fall on the same region that recently experienced an extreme wildfire.
They found that more than half of extreme wildfire events will be followed within a year by an extreme rainfall event across much of the West, and virtually all extreme wildfires in the Pacific Northwest will be followed within five years by extreme rainfall.
Once every three years, drenching rains in western Colorado or much of the Pacific Northwest may be expected to inundate regions just three months after extreme wildfires — a scenario that was virtually unheard of in recent decades.
Part of the reason for the confluence of extreme fire and rainfall has to do with how climate change is altering the seasonality of these events.
For example, the study found more extreme rains occurring in the early fall in Colorado and the Pacific Northwest, close to the peak fire season of May to September.
“The gap between fire and rainfall season is becoming shorter,” Touma said. “One season of disasters is running into another.”

MIDDLETOWN, Calif. — What does it mean to have the "Best Day Ever"?
Over 100 participants came together to find out at the Lake County Quality Care Counts, or LCQC, conference on March 19 at Twin Pine Casino in Middletown.
The Lake County Office of Education’s LCQC is a program that improves the quality of early learning for children ages zero through five by providing professional development, supplies and coaching to early childhood providers
"LCQC hosts this conference every year to provide inspiration, new ideas and high-quality professional development that early educators can use in their classrooms," said LCQC Director Angela Cuellar-Marroquin.
The conference succeeded in bringing together early childhood educators from across Northern California to participate and leave with new knowledge and passion for continuing their work.
“Optimizing the early years of children’s lives is the best investment we can make in our community to ensure their future success,” Lake County Superintendent of Schools Brock Falkenberg said.
The first presenter, Sharron Krull, gave a keynote about incorporating art with science. Krull is an early childhood consultant through her company, Play Power. She is a veteran preschool teacher with over 45 years’ experience that encompasses nearly all areas of early childhood education.
Steve Spangler finished the day with an inspiring and interactive keynote. Spangler is an Emmy award-winning television host, science communicator, and celebrity educator.
During his high-energy presentation, he covered that the "Best Day Ever" is more than just a feeling or an emotion. It is a powerful principle that helps people connect, engage and share experiences with each other.
Participants gave the conference high marks.
“Best training I’ve been to. Truly. After the last two years … feeling a smidge burnt out and bogged down,” said Jacqui Joyce of Miss Jacqui’s Childcare. “This training completely reminded me why I do what I do. Got me excited for Monday, and who gets excited for Mondays!?"
"I am beyond grateful for today’s conference. The inspiration I left with today, is going right back into my classroom on Monday,” said Jacklyn Edwards, a teacher at Pomo Elementary in the Konocti Unified School District.
"I had so much fun I almost cried when it was over. Shooting toilet paper out of a leaf blower was just way too much fun. The excitement of the whole day was truly the "Best Day Ever,” said Jody Mederos of the North Coast Opportunities Head Start program.

Taxonomy, the study of how living organisms relate to one another as species, has been around since the 1700s. Though scientists and philosophers have long debated what makes a species a species, taxonomists treat each species as a group of organisms that share common biological characteristics.
Discovering and describing new species is essential to biology researchers and conservationists because they use species as a unit of analysis. Species are also economically important to agriculture, hunting and fishing, and have special legal status, such as under the U.S. Endangered Species Act.
Despite this, scientists have been able to formally name and describe only an estimated 10% of species on the planet, based on discovery trends over the years.
We are scientists in evolutionarybiology, and figuring out ways to better identify species is central to our research. Using genetic analysis and artificial intelligence, we were able to disentangle hidden species that have been lumped together in a single group and predict where and what types they might be. Our findings also pinpoint a potential cause for this shortfall in species identification: an underinvestment in the science of taxonomy.
Hidden species remain to be discovered
For this study, we chose to focus on mammals. Because of their relatively large size and importance to people as a source of food, companionship and entertainment, we predicted that it was more likely that a large proportion of mammalian species have been already been identified.
Our first task was to identify known species that might actually contain two or more species. To do this, we analyzed 1 million gene sequences from 4,300 named species, identifying clusters of sequences that showed high genetic diversity and fitting the data to an evolutionary model.
We found potentially hundreds of hidden species that were previously classified as a single group. This finding was expected, as it mirrors results from previous studies, albeit on a larger scale.
Where and what are these hidden species?
Once we identified the presence of these potentially hidden species, our second task was to determine what specific traits they have in common. To do this, we used a data science technique called random forest analysis, a form of machine learning that draws information from a large number of different variables in order to make a prediction about a particular outcome. It’s similar to the technique that Netflix uses to suggest shows you might be interested in watching.
In our case, we wanted to predict whether a known species contained hidden species. The predictor variables we used spanned environmental factors, such as the climate of common mammalian habitats, and species-specific factors, such as physical traits, geographic range, reproductive and survival patterns. We also included research-based factors on the techniques scientists used to conduct their studies. In total, we collected some 3.8 million data points to build our model.
Based on our model, we found that three types of predictor variables stood out the most.
The first type comprised attributes of the species itself, such as body mass and geographic range. These results suggest that small mammals with relatively large ranges are more likely to have hidden species. This makes sense as, all things being equal, it is more difficult for scientists to recognize physical differences in smaller animals than larger ones.
The second type was climate – there are likely to be more hidden species in wet, warm areas with a large difference in day and night temperatures. This likely reflects the fact that tropical rainforests tend to have very high levels of mammalian diversity.
The third type was research effort, including the geographic dispersion of samples in museum collections and the number of recent publications mentioning the scientific name of a known species. This implies that researchers are generally effective in identifying new mammals, as how much attention the scientific community has focused on a specific mammal predicts whether that creature is identified. This is supported by how the general characteristics we’ve identified match new mammalian species described over the past 30 years, as well as the fact that our model recognizes areas that scientists are already investigating for hidden species.
Unknown species face extinction
At a time when Earth is facing its greatest extinction crisis since an asteroid killed off the dinosaurs, we believe that identifying and describing the many undiscovered species on Earth is crucial to aiding the preservation of its biodiversity.
Even though our study still found a large number of mammals waiting to be discovered, mammalian diversity is already relatively well captured compared with that of other species. We found that roughly 80% of existing mammal species have already been described, a proportion far higher than in nonmammal groups with even higher diversity such as beetles or mites.
Discovering and describing new species, as with all scientific research, takes a village. Natural history museums are largely responsible for collecting the raw data we analyzed, and genetic and biodiversity databases provided the infrastructure to make it accessible to us. A culture of information sharing among peers and large computer networks supported the thousands of hours of computation time we needed. Our work was made possible only by ongoing investments in taxonomic research.
Biodiversity scientists are racing to better understand the processes that create and maintain biodiversity while in the midst of the planet’s sixth mass extinction, one that is entirely caused by human actions. Taxonomists face the challenge of describing the species around us before they go extinct. As our findings suggest, there is still a long way to go.
NORTHERN CALIFORNIA — California’s snowpack is continuing to dwindle after months of dry weather.
The Department of Water Resources on Friday conducted the fourth snow survey of the season at Phillips Station.
Following three straight months of record dry conditions, the manual survey recorded just 2.5 inches of snow depth and a snow water equivalent of one inch, which is four percent of average for this location for April 1.
Statewide, the snowpack is just 38% of average for this date.
The snowpack at Phillips Station has plummeted since the beginning of the year, officials said.
On Dec. 30, the snowpack stood at 202% of normal for that date. In a normal season, the snowpack depth would be about five feet deep at this time of year.
The snow water equivalent measured at the snow survey shows the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast, including anticipated runoff into the state’s reservoirs.
April 1 is typically when the snowpack is at its highest, however the statewide snowpack likely peaked in early-March this year and the Northern Sierra snowpack peaked in mid-January.
“The conditions we are seeing today speak to how severe our drought remains. DWR has been planning for the reality of a third dry year since the start of the water year on October 1,” said DWR Director Karla Nemeth. “While DWR has made significant investments in forecasting technology and other tools to ensure we make the most out of the snowmelt we do receive, water conservation will remain our best tool in the face of this ongoing drought and the statewide impacts of a warming climate. All Californians must focus on conserving water now.”
Dry conditions are impacting every region of the state, as the Northern, Central, and Southern Sierra snowpacks are all standing just above 28% to 43% of average for this date.
“With the exceptionally dry conditions during the past three months, our latest statewide snowmelt forecasts are only 44% of average,” said Sean de Guzman, manager of DWR’s Snow Surveys and Water Supply Forecasting Unit. “While today usually marks the typical peak of the state’s snowpack, this year’s snowpack likely peaked in mid-January in the Northern Sierra. Most of the snow accumulation this year came from just two storms in December that were followed by the driest January and February on record in the Sierra, and unfortunately March only brought a few weak systems.”
“Today’s snow survey reinforces what we’ve all observed – California just experienced the driest three months on record, and drought is worsening throughout the West,” California Secretary for Natural Resources Wade Crowfoot said. “Climate-driven water extremes are part of our reality now, and we must all adapt and do our part to save water every day.”
While the state continues to take necessary actions to help extend the state’s existing water supply, all Californians are also encouraged to do their part now to conserve as much water as possible to make it last.
Gov. Newsom has called on all Californians to voluntarily reduce their water use by 15% with simple measures to protect water reserves.
Earlier this week, the governor called on local water suppliers to move to level two of their water shortage contingency plans, which require locally-appropriate actions that will conserve water across all sectors, and directed the State Water Resources Control Board to consider a ban on the watering of decorative grass at businesses and institutions.

Richard Forno, University of Maryland, Baltimore County
President Joe Biden on March 21, 2022, warned that Russian cyberattacks on U.S. targets are likely, though the government has not identified a specific threat. Biden urged the private sector: “Harden your cyber defenses immediately.”
It is a costly fact of modern life that organizations from pipelines and shipping companies to hospitals and any number of private companies are vulnerable to cyberattacks, and the threat of cyberattacks from Russia and other nations makes a bad situation worse. Individuals, too, are at risk from the current threat.
Local governments, like schools and hospitals, are particularly enticing “soft targets” – organizations that lack the resources to defend themselves against routine cyberattacks, let alone a lengthy cyber conflict. For those attacking such targets, the goal is not necessarily financial reward but disrupting society at the local level.
From issuing business licenses and building permits and collecting taxes to providing emergency services, clean water and waste disposal, the services provided by local governments entail an intimate and ongoing daily relationship with citizens and businesses alike. Disrupting their operations disrupts the heart of U.S. society by shaking confidence in local government and potentially endangering citizens.
I and other researchers at University of Maryland, Baltimore County have studied the cybersecurity preparedness of the United States’ over 90,000 local government entities. As part of our analysis, working with the International City/County Management Association, we polled local government chief security officers about their cybersecurity preparedness. The results are both expected and alarming.
Among other things, the survey revealed that nearly one-third of U.S. local governments would be unable to tell if they were under attack in cyberspace. This is unsettling; nearly one-third of local governments that did know whether they were under attack reported being attacked hourly, and nearly half at least daily.
Ill-equipped
Lack of sound IT practices, let alone effective cybersecurity measures, can make successful cyberattacks even more debilitating. Almost half of U.S. local governments reported that their IT policies and procedures were not in line with industry best practices.
In many ways, local governments are no different from private companies in terms of the cybersecurity threats, vulnerabilities and management problems they face. In addition to those shared cybersecurity challenges, where local governments particularly struggle is in hiring and retaining the necessary numbers of qualified IT and cybersecurity staff with wages and workplace cultures that can compare with those of the private sector or federal government.
Additionally, unlike private companies, local governments by their nature are limited by the need to comply with state policies, the political considerations of elected officials and the usual perils of government bureaucracy such as balancing public safety with the community’s needs and corporate interests. Challenges like these can hamper effective preparation for, and responses to, cybersecurity problems – especially when it comes to funding. In addition, much of the technology local communities rely on, such as power and water distribution, are subject to the dictates of the private sector, which has its own set of sometimes competing interests.
Large local governments are better positioned to address cybersecurity concerns than smaller local governments. Unfortunately, like other soft targets in cyberspace, small local governments are much more constrained. This places them at greater risk of successful cyberattacks, including attacks that otherwise might have been prevented. But the necessary, best-practice cybersecurity improvements that smaller cities and towns need often compete with the many other demands on a local community’s limited funds and staff attention.
Getting the basics right
Whether they are victimized by a war on the other side of the world, a hacktivist group promoting its message or a criminal group trying to extort payment, local governments in the U.S. are enticing targets. Artificial intelligence hacking tools and vulnerabilities introduced by the spread of smart devices and the growing interest in creating “smart cities” put local governments even more at risk.
There’s no quick or foolproof fix to eliminate all cybersecurity problems, but one of the most important steps local governments can take is clear: Implement basic cybersecurity. Emulating the National Institute of Standards and Technology’s national cybersecurity framework or other industry accepted best practices is a good start.
I believe government officials, especially at the local level, should develop and apply the necessary resources and innovative technologies and practices to manage their cybersecurity risks effectively. Otherwise, they should be prepared to face the technical, financial and political consequences of failing to do so.

Prakash Nagarkatti, University of South Carolina and Mitzi Nagarkatti, University of South Carolina
A new omicron subvariant of the virus that causes COVID-19, BA.2, is quickly becoming the predominant source of infections amid rising cases around the world. Immunologists Prakash Nagarkatti and Mitzi Nagarkatti of the University of South Carolina explain what makes it different from previous variants, whether there will be another surge in the U.S. and how best to protect yourself.
What is BA.2, and how is it related to omicron?
BA.2 is the latest subvariant of omicron, the dominant strain of the SARS-CoV-2 virus that causes COVID-19. While the origin of BA.2 is still unclear, it has quickly become the dominant strain in many countries, including India, Denmark and South Africa. It is continuing to spread in Europe, Asia and many parts of the world.
The first omicron subvariant, BA.1, is unique in the number of alterations it has compared to the original version of the virus – it has over 30 mutations in the spike protein that helps it enter cells. Spike protein mutations are of high concern to scientists and public health officials because they affect how infectious a particular variant is and whether it is able to escape the protective antibodies that the body produces after vaccination or a prior COVID-19 infection.
BA.2 has eight unique mutations not found in BA.1, and lacks 13 mutations that BA.1 does have. BA.2 does, however, share around 30 mutations with BA.1. Because of its relative genetic similarity, it is considered a subvariant of omicron as opposed to a completely new variant.
While standard PCR tests are still able to detect the BA.2 variant, they might not be able to tell it apart from the delta variant.
Is it more infectious and lethal than other variants?
BA.2 is considered to be more transmissible but not more virulent than BA.1. This means that while BA.2 can spread faster than BA.1, it might not make people sicker.
Does previous infection with BA.1 provide protection against BA.2?
Yes! A recent study suggested that people previously infected with the original BA.1 subvariant have robust protection against BA.2.
Because BA.1 caused widespread infections across the world, it is likely that a significant percentage of the population has protective immunity against BA.2. This is why some scientists predict that BA.2 will be less likely to cause another major wave
However, while the natural immunity gained after COVID-19 infection may provide strong protection against reinfection from earlier variants, it weakens against omicron.
How effective are vaccines against BA.2?
A recent preliminary study that has not yet been peer reviewed of over 1 million individuals in Qatar suggests that two doses of either the Pfizer–BioNTech or Moderna COVID-19 vaccines protect against symptomatic infection from BA.1 and BA.2 for several months before waning to around 10%. A booster shot, however, was able to elevate protection again close to original levels.
Importantly, both vaccines were 70% to 80% effective at preventing hospitalization or death, and this effectiveness increased to over 90% after a booster dose.
How worried does the US need to be about BA.2?
The rise in BA.2 in certain parts of the world is most likely due to a combination of its higher transmissibility, people’s waning immunity and relaxation of COVID-19 restrictions.
CDC data suggests that BA.2 cases are rising steadily, making up 23% of all cases in the U.S. as of early March. Scientists are still debating whether BA.2 will cause another surge in the U.S.
Though there may be an uptick of BA.2 infections in the coming months, protective immunity from vaccination or previous infection provides defense against severe disease. This may make it less likely that BA.2 will cause a significant increase in hospitalization and deaths. The U.S., however, lags behind other countries when it comes to vaccination, and falls even further behind on boosters.
Whether there will be another devastating surge depends on how many people are vaccinated or have been previously infected with BA.1. It’s safer to generate immunity from a vaccine, however, than from getting an infection. Getting vaccinated and boosted and taking precautions like wearing an N95 mask and social distancing are the best ways to protect yourself from BA.2 and other variants.
LAKE COUNTY, Calif. — Thanks to a $199,865 grant from the California State Library, a sleek new bookmobile is slated to traverse Lake County roads to bring library services to communities not currently served by a local branch.
Lake County Librarian Christopher Veach said it’s long been a goal of the library to better reach the differing and sometimes isolated regions of Lake County.
He believes that libraries are for everyone, wherever they live, and hopes to bring easier library access to more Lake County residents through the bookmobile.
Veach, a Lake County native who has served as its librarian since 2013, was inspired to apply for the grant as an extension of their desire to make libraries as accessible as possible during the COVID-19 pandemic.
He envisions that the bookmobile will be used to serve communities that are furthest from the four established branches in the county, the main branch in Lakeport, Redbud Library in Clearlake, and the branches in Upper Lake and Middletown.
The Riviera area and North Shore communities will be among the beneficiaries of the bookmobile’s visits, with regularly scheduled stops in areas where people tend to congregate.
Typically, a bookmobile stops at a venue for about an hour, so it’s likely it could make three or four stops a day based on a regular schedule. The plan is for the bookmobile to travel a prearranged route several times a week, with the other days devoted to visiting schools and making appearances at public events.
Most of the grant money will be used to cover the cost of the vehicle, which will be a Mercedes-Benz Sprinter van customized to the library’s specifications.
Some rural counties use larger vehicles as bookmobiles; Mendocino County, for example, has a camper-sized bookmobile. However, Veach feels the smaller size is more practical for Lake County’s narrow and sometimes mountainous roads, as well as easier for staff to commandeer.
Another benefit of a smaller vehicle is that it makes visits to schools and other venues, like farmers’ markets or festivals, much easier.
Customization can be a long process, and under normal circumstances can take up to a year. The mobile library may not be ready to hit the road until early 2023, particularly if supply challenges wrought by the pandemic wind up affecting the process.
The library is required to provide matching funds, and this will be met via the cost of operation, maintenance, and insurance over the period of the grant, which ends in 2024.
The bookmobile will be like a branch on wheels, where people can browse books, sign up for library cards and have access to the internet. Chromebooks and Wi-Fi hot spots — hockey puck-like portable devices that provide internet access — will be available for the public’s use on site or for checkout.
Immediate access to between 700 and 1,000 volumes will be possible via the bookmobile, and just like at current branches, books can be requested for pickup there.
The van will have shelves to house books both inside and outside, where open-air browsing can be done under a protective canopy. Depending on the weather, tables and chairs for patrons will be set up under the canopy outside.
The library, which currently employs 18 full-time and part-time employees across its four branches, will hire an additional part-time staff member to operate the bookmobile and serve as its library clerk.
According to Veach, who has a passion for expanding library services, the Lake County Library offers a broad array of programs and resources for children and adults that extend beyond access to books.
Children’s programming includes weekly story times, Lego clubs and special craft events, such as the wildly popular Leprechaun trap workshops offered last month in honor of St. Patrick’s Day.
Six new digital career resources for job seekers were launched at the end of last year. These are provided free of charge for patrons with library cards and can be accessed via the “job seekers and career sources” option on the library website.
The library has an Adult Literacy program which matches tutors with adults who need help with their reading, writing or language skills. Virtual tutor training is provided, and any interested in the program should contact the Lakeport branch at 707-263-7633.
According to Veach, April marks the launch of a “Book-to-Action” reading program for adults. Participants will have the opportunity to collectively read and discuss “The Blue Zones of Happiness” by Dan Buettner and put their newfound knowledge into action via a community service project. Free copies of the book are available at Lake County branches while supplies last.
As usual, the library will offer summer reading challenges for children and adults, along with prizes awarded when reading goals are met.
The library website, http://library.lakecountyca.gov, provides access to a plethora of online resources and information. Visitors to the site can sign up for a weekly email newsletter with information on special events, ongoing programs, volunteer opportunities and book recommendations.
News of the bookmobile’s launch will be announced via the newsletter, which is also available at any of the county’s library branches.

NASA’s Hubble Space Telescope has established an extraordinary new bench mark: detecting the light of a star that existed within the first billion years after the universe’s birth in the big bang — the farthest individual star ever seen to date.
The find is a huge leap further back in time from the previous single-star record holder; detected by Hubble in 2018. That star existed when the universe was about 4 billion years old, or 30 percent of its current age, at a time that astronomers refer to as “redshift 1.5.”
Scientists use the word “redshift” because as the universe expands, light from distant objects is stretched or “shifted” to longer, redder wavelengths as it travels toward us.
The newly detected star is so far away that its light has taken 12.9 billion years to reach Earth, appearing to us as it did when the universe was only 7 percent of its current age, at redshift 6.2. The smallest objects previously seen at such a great distance are clusters of stars, embedded inside early galaxies.
“We almost didn’t believe it at first, it was so much farther than the previous most-distant, highest redshift star,” said astronomer Brian Welch of the Johns Hopkins University in Baltimore, lead author of the paper describing the discovery, which is published in the March 30 journal Nature. The discovery was made from data collected during Hubble’s RELICS (Reionization Lensing Cluster Survey) program, led by co-author Dan Coe at the Space Telescope Science Institute, or STScI, also in Baltimore.
“Normally at these distances, entire galaxies look like small smudges, with the light from millions of stars blending together,” said Welch. “The galaxy hosting this star has been magnified and distorted by gravitational lensing into a long crescent that we named the Sunrise Arc.”
After studying the galaxy in detail, Welch determined that one feature is an extremely magnified star that he called Earendel, which means “morning star” in Old English. The discovery holds promise for opening up an uncharted era of very early star formation.
“Earendel existed so long ago that it may not have had all the same raw materials as the stars around us today,” Welch explained. “Studying Earendel will be a window into an era of the universe that we are unfamiliar with, but that led to everything we do know. It’s like we’ve been reading a really interesting book, but we started with the second chapter, and now we will have a chance to see how it all got started,” Welch said.
When stars align
The research team estimates that Earendel is at least 50 times the mass of our Sun and millions of times as bright, rivaling the most massive stars known.
But even such a brilliant, very high-mass star would be impossible to see at such a great distance without the aid of natural magnification by a huge galaxy cluster, WHL0137-08, sitting between us and Earendel.
The mass of the galaxy cluster warps the fabric of space, creating a powerful natural magnifying glass that distorts and greatly amplifies the light from distant objects behind it.
Thanks to the rare alignment with the magnifying galaxy cluster, the star Earendel appears directly on, or extremely close to, a ripple in the fabric of space.
This ripple, which is defined in optics as a “caustic,” provides maximum magnification and brightening. The effect is analogous to the rippled surface of a swimming pool creating patterns of bright light on the bottom of the pool on a sunny day. The ripples on the surface act as lenses and focus sunlight to maximum brightness on the pool floor.
This caustic causes the star Earendel to pop out from the general glow of its home galaxy. Its brightness is magnified a thousandfold or more. At this point, astronomers are not able to determine if Earendel is a binary star, though most massive stars have at least one smaller companion star.
Confirmation with Webb
Astronomers expect that Earendel will remain highly magnified for years to come. It will be observed by NASA’s James Webb Space Telescope. Webb’s high sensitivity to infrared light is needed to learn more about Earendel, because its light is stretched (redshifted) to longer infrared wavelengths due to the universe’s expansion.
“With Webb we expect to confirm Earendel is indeed a star, as well as measure its brightness and temperature,” Coe said. These details will narrow down its type and stage in the stellar life cycle. "We also expect to find the Sunrise Arc galaxy is lacking in heavy elements that form in subsequent generations of stars. This would suggest Earendel is a rare, massive metal-poor star,” Coe said.
Earendel’s composition will be of great interest for astronomers, because it formed before the universe was filled with the heavy elements produced by successive generations of massive stars.
If follow-up studies find that Earendel is only made up of primordial hydrogen and helium, it would be the first evidence for the legendary Population III stars, which are hypothesized to be the very first stars born after the big bang. While the probability is small, Welch admits it is enticing all the same.
“With Webb, we may see stars even farther than Earendel, which would be incredibly exciting,” Welch said. “We’ll go as far back as we can. I would love to see Webb break Earendel’s distance record.”
The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute, or STScI, in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.
What are some skywatching highlights in April 2022?
The gathering of planets in the morning sky increases three to four, as Jupiter joins the party. Two close conjunctions — between Mars and Saturn, and Venus and Jupiter — provide highlights at the beginning and end of the month. And the Big Dipper hosts a surprise: a double star you just might be able to "split" with your own eyes.
At the beginning of April, Venus, Mars and Saturn form a trio in the southeast before sunrise, with Saturn appearing to move steadily toward Mars each day.
On April 1, they're a couple of finger widths apart. And by April 4, Saturn and Mars are separated by less than the width of the full moon. Saturn then moves on, increasing its separation from Mars each day, as a new addition to the morning sky makes its debut.
By mid-month, Jupiter is starting to rise in the predawn hour, making for a quartet of planets, strung out in a line across the morning sky. Heading into the last week of April, Jupiter will be high enough above the horizon in the hour before sunrise to make it more easily observed.
The two brightest planets in the sky, Venus and Jupiter, are headed for their own ultra-close conjunction on April 30, similar to the meetup of Mars and Saturn earlier in the month. In fact, they approach to about the same distance.
Of course, the planets are actually far apart in space, and only appear to move closer, or farther apart, in the sky as our view of them across the solar system changes from month to month.
If you recall the grand conjunction of Jupiter and Saturn at the end of 2020, these conjunctions are not quite as close as that, but still really impressive and they'll make for thrilling sights in the morning sky. So definitely try to catch them if you can!
Whether you call it the Big Dipper, or Ursa Major, or the Plough, it's probably the most familiar pattern of bright stars in the northern sky. The Big Dipper is a really useful reference for finding your way around the sky, but it also contains a hidden surprise: One of its stars is really two. Or, actually, six. Let's break that down.
What looks at first glance like a single bright star here, midway along the Dipper's handle, is on closer inspection a double star: Mizar and Alcor. Next time you have a chance, try to see if you can perceive them as two stars with your own eyes. Once you give it a try, then grab binoculars if you have them, which will easily show them as separate stars.
The two star systems are around a light year apart, and are located 80 to 90 light years away from our solar system, with Alcor taking just shy of a million years to complete an orbit around Mizar.
Now, lots of stars are bound together by gravity in small groups, especially in pairs — or binaries — that orbit around each other. But usually it takes a telescope to be able to see them as separate stars. Mizar and Alcor are a rare example of a double star that you can see as a pair without the aid of a telescope.
But it gets more interesting: Although they appear as a close pair of two stars, they are in fact six. Alcor is a binary pair of stars, while Mizar is actually four stars — two pairs of binaries. So find the unusual "double" stars Mizar and Alcor in the Big Dipper in April,
