The Brief

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."

DUARTE, Calif. — Veteran actor T.K. Carter, who appeared in the horror film "The Thing" and "Punky Brewster" on television, has died at the age of 69.

Carter was declared dead Friday evening after deputies responded to a call regarding an unresponsive male in Duarte, California, according to the Los Angeles County Sheriff's Department.

Police did not disclose a cause of death or other details, but said no foul play was suspected.

Thomas Kent "T.K." Carter was born Dec. 18, 1956, in New York City and was raised in Southern California.

He began his career in stand-up comedy and with acting roles. Carter had been acting for years before a breakthrough role as Nauls the cook in John Carpenter's 1982 horror classic, "The Thing." He also had a recurring role in the 1980s sitcom "Punky Brewster."

Other big-screen roles include "Runaway Train" in 1985, "Ski Patrol" in 1990 and "Space Jam" in 1996.

"T.K. Carter was a consummate professional and a genuine soul whose talent transcended genres," his publicist, Tony Freeman, said in a statement. "He brought laughter, truth, and humanity to every role he touched. His legacy will continue to inspire generations of artists and fans alike."

People have been taking to the streets nationwide this weekend to protest the Trump administration's immigration enforcement tactics following the death of Renee Good in Minneapolis, a 37-year-old woman who was shot and killed by a U.S. Immigration and Customs Enforcement (ICE) officer this week.

At least 1,000 events across the U.S. were planned for Saturday and Sunday, according to Indivisible, a progressive grassroots coalition of activists helping coordinate the movement it calls "ICE Out For Good Weekend of Action."

Leah Greenberg, a co-executive director of Indivisible, said people are coming together to "grieve, honor those we've lost, and demand accountability from a system that has operated with impunity for far too long."

"Renee Nicole Good was a wife, a mother of three, and a member of her community. She, and the dozens of other sons, daughters, friends, siblings, parents, and community members who have been killed by ICE, should be alive today," Greenberg said in a statement on Friday. "ICE's violence is not a statistic, it has names, families, and futures attached to it, and we refuse to look away or stay silent."

Large crowds of demonstrators carried signs and shouted "ICE out now!" as protests continued across Minneapolis on Saturday. One of those protestors, Cameron Kritikos, told NPR that he is worried that the presence of more ICE agents in the city could lead to more violence or another death.

"If more ICE officers are deployed to the streets, especially a place here where there's very clear public opposition to the terrorizing of our neighborhoods, I'm nervous that there's going to be more violence," the 31-year grocery store worker said. "I'm nervous that there are going to be more clashes with law enforcement officials, and at the end of the day I think that's not what anyone wants."

The night before, hundreds of city and state police officers responded to a "noise protest" in downtown Minneapolis. An estimated 1,000 people gathered Friday night, according to Minneapolis Police Chief Brian O'Hara, and 29 people were arrested.

People demonstrated outside of hotels where ICE agents were believed to be staying. They chanted, played drums and banged pots. O'Hara said that a group of people split from the main protest and began damaging hotel windows. One police officer was injured from a chunk of ice that was hurled at officers, he added.

Minneapolis Mayor Jacob Frey condemned the acts of violence but praised what he said was the "vast majority" of protesters who remained peaceful, during a morning news conference.

"To anyone who causes property damage or puts others in danger: you will be arrested. We are standing up to Donald Trump's chaos not with our own brand of chaos, but with care and unity," Frey wrote on social media.

Commenting on the protests, Department of Homeland Security (DHS) spokesperson Tricia McLaughlin told NPR in a statement, "the First Amendment protects speech and peaceful assembly — not rioting, assault and destruction," adding, "DHS is taking measures to uphold the rule of law and protect public safety and our officers."

Good was fatally shot the day after DHS launched a large-scale immigration enforcement operation in Minnesota set to deploy 2,000 immigration officers to the state.

In Philadelphia, police estimated about 500 demonstrators "were cooperative and peaceful" at a march that began Saturday morning at City Hall, Philadelphia Police Department spokesperson Tanya Little told NPR in a statement. And no arrests were made.

In Portland, Ore., demonstrators rallied and lined the streets outside of a hospital on Saturday afternoon, where immigration enforcement agents bring detainees who are injured during an arrest, reported Oregon Public Broadcasting.

A man and woman were shot and injured by U.S. Border Patrol agents on Thursday in the city. DHS said the shooting happened during a targeted vehicle stop and identified the driver as Luis David Nino-Moncada, and the passenger as Yorlenys Betzabeth Zambrano-Contreras, both from Venezuela. As was the case in their assertion about Good's fatal shooting, Homeland Security officials claimed the federal agent acted in self-defense after Nino-Moncada and Zambrano-Contreras "weaponized their vehicle."

Bob Weir, the guitarist and songwriter who was a founding member of the popular and massively influential American rock band the Grateful Dead, has died. According to a statement from his family posted on his website and social media pages, Weir died from underlying lung issues after recently beating cancer. He was 78.

A member of the Dead for its first three decades, and a keeper of the flame of the band's legacy for three more, Weir helped to write a new chapter of American popular music that influenced countless other musicians and brought together an enormous and loyal audience. The Grateful Dead's touring, bootlegging and merchandising set an example that helped initiate the jam-band scene. Its concerts created a community that brought together generations of followers.

Known to fans as "Bobby," he was born in San Francisco as Robert Hall Parber, but was given up for adoption and raised by Frederick and Eleanor Weir. In 1964, when he was still a teenager, Weir joined guitarist Jerry Garcia in a folk music band, Mother Mcree's Uptown Jug Band. In May of 1965 Weir and Garcia were joined by bassist Phil Lesh, keyboard player Ron "Pigpen" McKernan and drummer Bill Kreutzmann to form an electric, blues-based rock and roll band that was briefly named The Warlocks. After discovering that there was another band using that name, Jerry Garcia found a phrase that caught his eye in a dictionary and in December of that year they became the Grateful Dead, launching a 30-year run over which time they grew into a cultural institution.

Weir was a singular rhythm guitarist who rarely played solos, choosing instead to create his own particular style of chording and strumming that gracefully supported Garcia's distinctive guitar explorations especially during the extended jams which were the heart of the band's popularity.

Lyrics were largely a product of a communal effort between Weir and Garcia, as well as lyricists John Perry Barlow, Robert Hunter, that often blurred the lines between who wrote what. The opening lines to "Cassidy," which first appeared on Weir's 1972 solo album Ace and was played by the Dead on live recordings including the 1981 double album Reckoning, reflect the combination of metaphor, rhyme and storytelling set to memorable melodies that the band's audiences could memorize, analyze and sing along to:

I have seen where the wolf has slept by the silver stream
I can tell by the mark he left you were in his dream
Ah, child of countless trees
Ah, child of boundless seas
What you are, what you're meant to be
Speaks his name, though you were born to me
Born to me, Cassidy

Weir's emotive singing, on "Cassidy" and other songs like "Sugar Magnolia," "One More Saturday Night" and the band's unofficial theme, "Truckin', " often included whoops and yells, in contrast to Garcia's calm and steady approach. His occasional tendency to forget lyrics was usually greeted by thunderous applause from fans.

After Garcia's death in 1995, at age 53, the surviving members of the band carried on in various forms and arrangements, the longest running of which was Weir's Dead & Company, which also featured Grateful Dead drummers Kreutzmann and Mickey Hart. Weir and the band concluded their "final tour" in July of 2023, but then returned to the stage for two extended residencies at the Sphere in Las Vegas, in 2024 and 2025.

A self-described "compulsive music maker," in 2018 Weir formed yet another band to mine the depths of the Grateful Dead catalog. It was a stripped-down guitar, acoustic bass and drums outfit that he called Bobby Weir & Wolf Bros. Its members included renowned bassist and producer Don Was.In October of 2022, Weir & Wolf Bros worked with a classical music arranger to present yet another iteration of the Dead's catalog, notable for never being played the same way twice, with a group that largely only plays what's written on the paper in front of them, the 80-piece National Symphony Orchestra.

In a 2022 interview with NPR, Weir explained the reason for that collaboration, and in doing so, seemed to offer a possible explanation for why the band's music stayed so popular for so long: "These songs are … living critters and they're visitors from another world — another dimension or whatever you want to call it — that come through the artists to visit this world, have a look around, tell their stories. I don't know exactly how that works, but I do know that it's real."

After Jerry Garcia's death in 1995, Weir kept the legacy of the Grateful Dead alive, touring with bands that came to include generations of musicians influenced by the group. Here, Weir performs with The Dead at Madison Square Garden in New York City in 2009.

Weir's work to shepherd and sustain the Dead's legacy was rewarded by ever younger generations of Deadheads, the band's loyal following, who attended tour after tour, often following the band from city to city as their parents and grandparents did during in the 1960's, '70s, '80s and '90s.

In an interview with Rolling Stone in March 2025, Weir shared his thoughts on his legacy, as well as on death and dying, that had a hint of the Eastern philosophies that were popular when the Grateful Dead emerged from the peace and love hippie movement of San Francisco. "I'll say this: I look forward to dying. I tend to think of death as a reward for a life well-lived," he said.
