    The James Webb Space Telescope is the most powerful telescope ever put into space. As such, its helping usher in a new era of astrophysics. Astronomers can now study farther, earlier galaxies than ever before.

    "If you were a paleontologist, you would dig deeper and deeper to find the oldest bones. In astronomy, what we do is look at our history," says Jorge Moreno, an associate professor of astronomy at Pomona College. "We have to look back in time, but we don't have a time machine. So what we do is we look at really faraway distances."

    As they peer into the deep, distant history of the universe, scientists are shocked to find galaxies showed in our cosmic history much sooner than scientists ever expected.

    It's a galactic controversy that has astronomers around the world excited — and puzzled.

    So what is it about these galaxies that is getting astronomers worked up? Not only is JWST finding galaxies forming 200-500 million years after the Big Bang, but also that they are bigger and brighter than astronomers expected.

    Using light to peer into the past

    The farthest galaxies seen by the telescope are also some of the earliest galaxies in our universe. The James Webb Space Telescope can see them because it is picking up the faint light emitted by them.

    By the time light from these far reaches of the universe approaches the telescope, it is in the infrared range of light, and no longer viewable to the naked eye. The light visible to humans is just a fraction of the total range of light on the electromagnetic spectrum.

    Cosmological redshift is the process by which wavelengths of light elongate as they travel through the expanding universe.

    This light has been traveling a long time by the time it reaches the telescope. For reference, it takes around eight minutes for light to travel from the sun to your eye. Light from Proxima Centauri, the nearest stellar neighbor of the sun, takes a little over four years to reach us here on earth.

    Seeing a teenager when you expect a kindergartener

    Light is a double-edged sword in the context of these galaxies. Its what lets us study the galaxies. But there's so much more of it than astronomers would have expected.

    The brightness of a galaxy can be related to its mass, because a galaxy's light comes from stars. If you assume a certain average brightness and mass of a star, you can roughly estimate the mass of a galaxy.

    But much of the modeling astronomers have done up to this point has led them to believe that there wasn't enough time for galaxies to get this massive in so little time.

    "It's like if you went to a kindergarten and you saw a teenager," says Moreno.

    However, Moreno says this assumption that brightness equates to mass may not always be accurate. For example, there could be an active supermassive black hole at the center of these early galaxies with bright accretion disks or high energy jets that would make the galaxies seem artificially massive. Or, if there's hot dust in the galaxies—which looks very bright in the infrared wavelengths picked up by the James Webb Space Telescope—that too would make the galaxies seem more massive than they are.

    When young galaxies are advanced for their age

    Most galaxies are separated into two types: spirals, which are disk-like with arms of dust and gas; and ellipticals, which are more like spheres of smooth light.

    Until now, scientists thought that any galaxies from this relatively early period in the history of the universe would have been too young to have been forced into that binary yet. Instead, astronomers thought the galaxies would be ... blobs. But Moreno and other astronomers like him are excited to now be studying what look like pretty highly structured galaxies.

    "Some of them look a lot like galaxies in the local universe," he says. "They seem to have added structure and maybe even spiral arms. That wasn't something we really expected."

    The high level of structure and brightness in these galaxies is leading some astrophysicists to question the age of the universe.

    The universe doesn't look a day over 13.8 billion years old

    Roughly.

    In an attempt to explain the shockingly bright, highly structured — and possibly quite massive — galaxies existing so early in the timeline of the universe, a researcher has posited that the universe is roughly twice as old as previously believed. They push the age of the universe from a spry 13.8 billion years old to roughly 26.7 billion years old.

    An article published earlier this year in the journal Monthly Notices of the Royal Astronomical Society came to this conclusion after combining two models of the universe. One is the commonly accepted model for the expansion of the universe. This model explains that as the universe expands, the light from galaxies must travel further and therefore shifts from a bluer to a redder spectrum of light. The other model it is combined with has been debunked. It's called the tired light model, and it alleges that as light travels across the universe, it gets redder because it gets "tired," or loses energy.

    Moreno says that while he thinks that combining the models is clever, it is not supported by scientific evidence.

    "I think in science, if you already have a model that's simpler than that, you should stick to it—unless you have extraordinary evidence to do otherwise."

    Moreno also cautions people against quickly jumping on this supposition that the universe is twice as old as previously thought. If it were true, scientists would be able to prove it through the direct observation of stars and galaxies that are older than 13.8 billion years old—the current accepted age of the universe.

    No such evidence has been found.

    Pausing to take in ancient, galactic wisdom

    NASA receives more data from the James Webb Space Telescope everyday—and with additional data comes possibilities for new solutions.

    But for Moreno, pausing for reflective moments about the conclusions we make based on observations are also important.

    So too, are lessons from these galaxies, which Moreno notes alternately go through periods of brightening and dimming. "I think that's something we need to learn from them—that it's important to just have times where we're really excited to discover things. But there are times where we need to quiet down, take a break and really think through things clearly and slowly."

  • Here's a roundup of the fires in SoCal
    Several buildings are seen next to a cove on a rugged island.
    A fire on Santa Rosa Island has been burning since May 15, 2015. The island is seen here in 1997.

    Topline:

    Several fires are burning across Southern California, with some destroying structures, threatening homes and charring pristine landscapes.

    Where are the fires? A large fire is burning on Santa Rosa Island in Channel Islands National Park. A fire in Simi Valley has destroyed one home and led to multiple evacuation alerts. Two fires are in Riverside County, and a small fire is in the San Gabriel Mountains.

    The forecast: Warm weather and Santa Ana wind conditions have hampered firefighting efforts and are expected to continue through Wednesday this week.

    Several fires are burning across Southern California, with some destroying structures, threatening homes and charring pristine landscapes.

    Warm weather and Santa Ana wind conditions have hampered firefighting efforts and are expected to continue through Wednesday this week. The National Weather Service forecasts cooler weather and "May gray" through the weekend.

    Here's a roundup of some of the fires burning now.

    (All dates refer to today, Tuesday, May 19, unless otherwise noted)

    Santa Rosa Island Fire (Santa Barbara County)

    The fire is burning in Channel Island National Park territory. Firefighters traveled by boat with their equipment to get to the island, according to news reports. The island is home to rare and endangered plants and animals.

    Sandy Fire (Ventura County)

    CalFire reported about 2:40 p.m. Tuesday that lessening winds allowed "firefighters to take full advantage of improved weather to strengthen containment lines and continue aggressive suppression efforts. Crews remain actively engaged both on the ground and in the air to gain additional containment and keep the fire within its current perimeter."

    The fire started Monday in the southern part of Simi Valley. It eventually spread eastward toward L.A. County communities in the San Fernando Valley, but overnight conditions were favorable to firefighters, CalFire said. Several communities were under evacuation orders and warnings, and schools in the area were closed.

    Bain Fire (Riverside County)

    The fire was first reported around noon Tuesday, according to CalFire, near Jurupa Valley (east of the 15 Freeway and south of the 60). CBS News Los Angeles reported that four people have been injured.

    Verona Fire (Riverside County)

    Burro Fire (Angeles National Forest)

    The fire started Monday in a mountainous area north of the San Gabriel Reservoir.

  • Ethics Commission to serve as corruption watchdog
    A woman with reddish hair, glasses and light-tone skin speaks on screen as her name (Lindsey P. Horvath) and agenda item appears in the lower thirds.
    Supervisor Lindsey Horvath sponsored the motion to create an L.A. County Ethics Commission.

    Topline:

    Citing a desire to prevent corruption within county government, the Board of Supervisors on Tuesday established Los Angeles County’s first ethics commission.

    The backstory: In 2024, voters approved Measure G, which called for the creation of an Ethics Commission and Office of Ethics Compliance. The measure came amid a series of corruption cases at L.A. City Hall but calls for reform spilled over into the county government.

    The details: The motion by Supervisor Lindsey Horvath and approved by the board Tuesday directs county departments to begin establishing the operational, staffing and legal infrastructure necessary to launch the commission in this year. It also directs staff to prepare a charter amendment for voter consideration on the November ballot to enshrine the commission in the charter.

    Composition: Supervisors voted for a plan that calls for a seven-member commission. One member would initially be appointed by the Governance Reform Task Force then by the county executive position to be created in 2029.

    Four members would be appointed by the chair of the Board of Supervisors, county assessor, district attorney and sheriff. The final two members would be selected through an application process administered by the Registrar of Voters.

    Opposition: Supervisor Janice Hahn supported the overall motion but opposed the composition of the commission, saying too many members were to be appointed by elected officials — the same people the panel would be charged with watchdogging.

    History: The county has had its own campaign, lobbying and ethics laws on the books for years, but they were enforced by ethics officers in various departments. The proposal calls for a 54-member ethics office now to enforce them and the commission to impose fines.

  • CA community colleges crack down on fake students

    Topline:

    After a spike in fraudulent applications to California’s community colleges, school officials say they are getting better at detecting and preventing fraud, though it still happens.

    Why it matters: Between January and March 2025, scammers stole nearly $5.6 million in federal student aid and over $900,000 in state aid. By comparison, this spring colleges have reported losing just under $1.5 million in federal student aid and about $330,000 in state aid to fraudsters. Last spring was “really the peak,” Hadsell said. He said he anticipates the end-of-year total in 2026 to be “significantly lower” than last year.

    The backstory: Last spring, CalMatters reported that colleges were seeing unprecedented reports of fraud, with scammers stealing millions more dollars of student aid than in any previous period, according to reports submitted by colleges to California’s Community Colleges Chancellor’s Office.

    California’s community colleges have been battling fraudulent students for years, trying to prevent scammers from stealing financial aid money.

    Recent data shows the colleges’ efforts finally may be working.

    Last spring, CalMatters reported that colleges were seeing unprecedented reports of fraud, with scammers stealing millions more dollars of student aid than in any previous period, according to reports submitted by colleges to California’s Community Colleges Chancellor’s Office.

    Now fewer scammers are bypassing colleges’ vetting systems, according to monthly reports, and school administrators say they’re better, though still not perfect, at detecting and preventing fraud.

    After CalMatters reported on the rise in fraud last year, Republican U.S. Congress members called for a federal investigation, a Democratic state legislator launched a state audit and later, California’s Community Colleges Chancellor’s Office approved a new ID verification policy for students. Colleges now are more vigilant about policing fraud, said Jory Hadsell, an executive in technology initiatives for the chancellor’s office, who pointed to better filtering practices and new software to detect fraud.

    Between January and March 2025, scammers stole nearly $5.6 million in federal student aid and over $900,000 in state aid. By comparison, this spring colleges have reported losing just under $1.5 million in federal student aid and about $330,000 in state aid to fraudsters.

    Last spring was “really the peak,” Hadsell said. He said he anticipates the end-of-year total in 2026 to be “significantly lower” than last year.

    Even in the worst months, such as last spring, the money distributed to scammers is less than 1% of the total financial aid distributed to community college students in California. Students use the money to help pay for tuition, books and the cost of daily living expenses, such as rent, transportation and food.

    But any fraud, however small, is unacceptable, said Chris Ferguson, executive vice chancellor of finance and strategic initiatives. “The ultimate goal for our system is zero.”

    Some anti-fraud policies have been slow to take effect. The California Community Colleges Board of Governors voted nearly a year ago to require ID verification for all students, but only about 50% of college students are doing it as of this month. Hadsell said the delays arose in part because of complications verifying information of students under 18 years old, who represent a growing demographic for the community colleges. He said ID verification, which is currently optional, will become mandatory on July 1.

    The board also voted to “explore” the option of charging students an application fee of no more than $10, but with the rates of fraud declining and other solutions that seem to work, the chancellor’s office is no longer pursuing that option, Ferguson said.

    After blaming California officials, the U.S. Department of Education, which shares responsibility for administering federal aid and detecting fraud, said it would implement a “screening process” for applicants. It was supposed to take effect last fall but didn’t launch until last month, according to press releases from the department and statements from the California Student Aid Commission. CalMatters reached out to the U.S. Education Department five times over the last 12 months, seeking clarification, but the department has refused to respond to questions about delays with the screening process.

    When more than a third of college applicants are fake

    After classes suddenly moved online during the COVID-19 pandemic, the California Community Colleges Chancellor’s Office saw an increase in financial aid fraud on their application portal, CCCApply, which is used by nearly every student as the first step in applying to community college.

    In 2021, the chancellor’s office suspected roughly 20% of applicants were fraudulent.

    The estimate was higher in January 2024, around 25%. Last spring, it was 34%, though some schools saw much higher rates.

    After they apply through CCCApply, students get filtered locally at their college of choice. In the Los Rios Community College District, which represents Sacramento, college officials suspected 64% of local applications from January to March 2025 were fraudulent. And that was after the state already vetted them through its portal, said Gabe Ross, a spokesperson for the district. The San Diego and Los Angeles community college districts also reported spikes in the number of fraudulent applications around the same time.

    CalMatters reached out to the five largest community college districts for an interview. The Rancho Santiago Community College District, which includes parts of Orange County, did not provide sufficient data to draw conclusions about trends in fraud. The State Center Community College District, which represents schools in Fresno and Madera counties, did not respond to CalMatters’ questions.

    Monthly data reports to the chancellor’s office show that once detected, most scammers who applied to community colleges were then caught and kicked out before they could apply for financial aid, but some succeeded.

    This year, both Sacramento and San Diego community colleges say they’re seeing fewer attempts at fraud and are getting better at stopping those who try. The San Diego Community College District is now manually screening for fraudulent applications twice a week and is finalizing a contract with a company to help improve its detection software.

    CCCApply has improved its filtering process, which helped reduce fraud attempts at Sacramento area colleges, said Ross. “When we talked about such a complex dynamic challenge, it's always hard to identify what's the one thing that sort of moved the needle. The truth is that we needed support from the feds, we needed support from the (chancellor’s) office, and we needed to invest in tools locally.”

    This spring, he said the district flagged about 12% of college applications as suspect.

    Using AI to detect AI 

    Measuring fraud is, by definition, imprecise. If a scammer is truly successful, colleges have no way to identify that fraud.

    For a long time, administrators assumed bots enrolling in online classes were responsible for most fraudulent attempts. Yet teachers, students and financial aid administrators say some of the scams are more sophisticated now and are coming from real people impersonating students. Many fraudulent applications to Los Angeles’ community colleges have real names, dates of birth, and addresses that are likely “leaked or stolen,” said Nicole Albo-Lopez, the deputy chancellor of the Los Angeles Community College District.

    In San Diego, Victor DeVore, dean of student services, said the college district only requires ID verification for students flagged as fraudulent. At that point they must prove their identity, either in person or through Zoom. Once, a potentially fraudulent student appeared on Zoom and presented a valid-looking ID that matched their face, but DeVore’s team noticed that the student’s IP address was odd. “One minute they’re logging in from Nairobi, the next minute they'll be logging in from Virginia,” he said, adding that the use of AI, virtual private networks (VPNs) or other technology has made fraud harder to detect.

    Students’ personal data is supposed to be private, but school districts and education technology companies are frequently hacked. Last week, Canvas — one of the go-to learning platforms for California’s community colleges, University of California and California State University campuses — went offline temporarily due to a major hack. Its parent company, Instructure, said last week that it reached an agreement with the hackers to relinquish students’ data.

    The state has turned to AI to fight fraud. Last summer, the state chancellor’s office negotiated a multimillion dollar contract with N2N Services Inc., enabling any college in the state to access the company’s software at a discounted rate. The software uses AI to detect potentially fraudulent applicants. Colleges are not required to use it, and so far, only about two-thirds do. Some districts, such as the Los Angeles Community College District, use a different fraud detection software, known as Socure.

    Colleges and the state chancellor’s office continue to face political pressure and scrutiny of their approach to fraud. Last month, the U.S. Education Department said it had prevented more than $171 million in fraud in California after implementing a new policy regarding ID verification. Hadsell, with the state chancellor’s office, said the federal policy had no impact on California’s colleges. “They issued some interim guidance last year that basically said you should at least have a Zoom call with students and have them show an ID when you're approving their aid. And those were things that were already happening. It was not, you know, some new thing at least for most of our colleges.”

    Kiran Kodithala, the CEO of N2N, which collects its own data on fraud at community colleges, said the education department’s claim makes no sense.

    “I don’t see how $171 million in fraud in California can occur,” he said. “There’s no basis for those numbers. We’re not seeing anything remotely close.” Kodithala estimates that N2N has prevented over $34 million in fraud since last summer, though his platform is not yet in use by all of California's 116 community colleges.

    Collecting more precise data may take months or years. U.S. Representative Young Kim, who represents parts of Orange, Riverside and San Bernardino counties, launched the effort for a federal investigation last spring, but her office could not provide any updates or confirm that an investigation was in fact underway. At the state level, the Legislature last year approved conducting an audit of how California’s community colleges handled fraud but the findings won’t be released until this summer.

  • LA County lifts rent-gouging ban 16 months later
    Flames from a large fire burn a residential building at night.
    The long-standing countywide prohibition on rent gouging will expire May 29.

    Topline:

    Landlords in Los Angeles County will soon be allowed to raise rents by more than 10% from their baseline before the January 2025 fires.

    The vote: A vote by the county’s Board of Supervisors that could have extended a ban on post-fire price gouging for another month failed on Tuesday. Supervisors Lindsey Horvath and Hilda Solis voted in favor, but Supervisors Kathryn Barger, Janice Hahn and Holly Mitchell abstained.

    The details: As a result, the long-standing countywide prohibition on rent gouging will expire on May 29. The milestone comes more than 16 months after the L.A. fires destroyed thousands of homes and plunged families into a hectic rental market.

    Landlords in Los Angeles County will soon be allowed to raise rents by more than 10% from their baseline before the January 2025 fires.

    A vote by the county’s Board of Supervisors that could have extended a ban on post-fire price gouging for another month failed on Tuesday. Supervisors Lindsey Horvath and Hilda Solis voted in favor, but Supervisors Kathryn Barger, Janice Hahn and Holly Mitchell abstained.

    As a result, the long-standing countywide prohibition on rent gouging will expire May 29. The milestone comes more than 16 months after the L.A. County fires destroyed thousands of homes and plunged families into a hectic rental market.

    Arguments for and against keeping post-fire rent limits

    In her motion to keep the rules in place through June 27, Horvath argued the ban should be preserved because about two-thirds of fire survivors are still in temporary housing.

    Horvath wrote that many families “have run out of financial displacement coverage from their insurance companies, which reinforces the need to continue price gouging restrictions, to protect these homeowners from drastic price increases.”

    In a statement Tuesday afternoon, Horvath said she was "deeply disappointed" that most of her colleagues abstained from the vote.

    "We continue hearing from residents who are struggling to recover financially and stay housed as they rebuild," she said.

    Landlord groups have been pushing county leaders for months to end the rent gouging ban. During public comment in Tuesday’s meeting, Jesus Rojas with the Apartment Association of Greater Los Angeles said the rules have long outlived the post-fire emergency.

    “They are wrongfully being used to harm thousands of rental housing providers throughout the entire county,” Rojas said. “This must stop, and it must stop now.”

    How the rules have worked so far 

    In March, the county ended post-fire price gouging restrictions on hotels, because survey data found that few displaced families were still staying in temporary motel rooms. Horvath argued the rent-gouging ban should be continued until the Department of Consumer and Business Affairs could deliver further data on resident displacement and the rental market.

    The rules have banned landlords from raising rents by more than 10% from advertised pre-fire levels. They also prohibited rents exceeding 200% of fair market value, as established by the U.S. Department of Housing and Urban Development, on previously unlisted properties.

    Tenant advocates found thousands of likely violations

    Following the 2025 Palisades and Eaton Fires, prosecutors filed a handful of misdemeanor charges against landlords and real estate agents accused of violating the price gouging rules.

    In the days after the fires, LAist spoke with one agent who encouraged her client to raise the rent on a Bel Air home nearly 86% from a previous 2024 listing.

    The agent, Fiora Aston with Compass, said at the time, “I've never seen anything like this. People are desperate. There’s so many families without a house.”

    The listing was later taken down. But tenant advocates with a group called The Rent Brigade started compiling data on other listings that appeared to violate price-gouging laws. By January 2026, the group reported finding 18,360 listings featuring likely violations.
