Astronomers have detected one of the longest, brightest and most energetic cosmic objects ever observed — and they’ve named it “Scary Barbie,” in part due to its terrifying power.

The remote object, an astonishingly bright flash of light that has lasted for more than two years, was discovered lurking inside an enormous data set gathered by computer-guided telescopes.

After finding the brightly burning patch of sky in the data and cross-referencing it with observations made by other telescopes, the astronomers realized they had stumbled across one of the most powerful cosmic explosions ever witnessed. They reported their findings April 17 on the preprint server arXiv (opens in new tab) , and their paper has been accepted for publication in The Astrophysical Journal Letters.

“It’s absurd. If you take a typical supernova and multiply it a thousand times, we’re still not at how bright this is — and supernovas are among the most luminous objects in the sky,” co-author Danny Milisavljevic (opens in new tab) , an assistant professor of physics and astronomy at Purdue University, said in a statement (opens in new tab) . “This is the most energetic phenomenon I have ever encountered.”

Scary Barbie was born from the final death throes of a star being torn to shreds by a supermassive black hole.

Black holes feed upon unfortunate stars that cross their paths, using tidal forces exerted by their immense gravitational pulls. As the star is reeled ever closer to the black hole’s maw, the gravity affecting the regions of the star closer to the black hole is far stronger than that acting on the star’s farside. This disparity “spaghettifies” the star into a long, noodle-like string that gets tightly wound around the black hole layer by layer — like spaghetti around a fork. 

This noodle of hot plasma then quickly accelerates around the black hole and spins out into an enormous jet of energy and matter, which produces a distinctive bright beam of light — known as a transient event — that optical, X-ray and radio-wave telescopes can detect.

Because Scary Barbie’s light came from a remote region of the sky — traveling around 7.7 billion years across the expanding fabric of space-time — astronomers didn’t spot the event directly. Instead, by developing a machine-learning system called Recommender Engine For Intelligent Transient Tracking, the researchers combed through data from many observations before finding the extremely bright light source. By using the Lick Observatory in California and the Keck Observatory in Hawaii, the researchers were better able to characterize the light as coming from a transient event. related stories—1st image of our galaxy’s ‘black hole heart’ unveiled

But Scary Barbie — a nickname made by appending its randomly assigned alphanumeric name, ZTF20abrbeie, with a reference to its frightening power — is weird even among other rare and extreme astronomical events. It is much brighter than any other transient event the astronomers could compare it to, and, while transient events usually last only weeks or months, Scary Barbie has already burned incandescently for more than two years, with no indication it will sputter out.

The astronomers said further observations of Scary Barbie, possibly using the Hubble Space Telescope and the James Webb Space Telescope, could enable them to snap some high-resolution images of the incredibly rare cosmic outburst.

“There are few things in the universe that can be so powerful, reactions that can be this long-lived,” Milisavljevic said. “Discoveries like this really open our eyes to the fact that we are still uncovering mysteries and exploring wonders in the universe — things no one has ever seen before.”

Doctor who supplied ketamine to late Friends star Matthew Perry jailed

A doctor who pleaded guilty to illegally supplying ketamine to Matthew Perry in the weeks before the star’s death has been jailed for two-and-a-half years.

Salvador Plasencia, who operated an urgent-care clinic outside Los Angeles, is the first of five people to be sentenced in connection with the death of the Friends actor. Perry was found drowned in the hot tub at his home after taking ketamine in October 2023.

“You and others helped Mr Perry on the road to such an ending by continuing to feed his ketamine addiction,” Judge Sherilyn Peace Garnett told Plasencia as she handed down the sentence. “You exploited Mr Perry’s addiction for your own profit.”

During the hearing, Plasencia broke into tears as he spoke about the day he would have to tell his now two-year-old son “about the time I didn’t protect another mother’s son”. Apologising directly to Perry’s family, he said: “I should have protected him.”

The doctor’s mother cried loudly in the courtroom as he was led out in handcuffs.

Ahead of the sentencing, Perry’s mother Suzanne Perry and stepfather Keith Morrison described those involved in supplying ketamine to the star illegally as “jackals”, and said they believed Plasencia to be “among the most culpable of all“.

The actor had been taking ketamine legally as a treatment for depression, but started seeking more of the drug and taking it unsupervised in the weeks before his death, acquiring it illegally from different sources.

Plasencia, 44, did not supply the dose that killed the actor, but had been distributing the surgical anesthetic to him in the weeks beforehand.

He initially denied the charges against him but changed his plea earlier this year, admitting four counts of distribution. He could have faced up to 40 years in prison had he been convicted at trial.

Doctor ‘fed on vulnerability’

Court documents showed details of a text message Plasencia sent to another doctor, who is also due to be sentenced, saying: “I wonder how much this moron will pay.”

“Rather than do what was best for Mr Perry – someone who had struggled with addiction for most of his life – [Plasencia] sought to exploit Perry’s medical vulnerability for profit,” the prosecution said in its sentencing memo.

Known as “Dr P”, Plasencia was introduced to Perry by one of his own patients on 30 September 2023, prosecutors said. This patient said the actor was a “high profile person” who was willing to pay “cash and lots of thousands” for ketamine treatment, and the doctor was “motivated by the promise of a payday”.

Plasencia’s lawyers admitted his behaviour was “reckless” and said it was “the biggest mistake” of his life.

“Remorse cannot begin to capture the pain, regret and shame that Mr Plasencia feels for the tragedy that unfolded and that he failed to prevent,” they said.

Star’s family share emotional statements

During the hearing, Perry’s mother Suzanne addressed the court to talk about everything he had overcome in his life.

“I used to think he couldn’t die,” she said, supported by her husband.

“You called him a ‘moron’,” she said to Plasencia. “There is nothing moronic about that man.”

In victim impact statements submitted to court, she and her husband said Plasencia’s actions were not the result of “one very bad decision” or done “in the heat of passion”, and nor was he a “bad to the bone” drug dealer.

They added: “No one alive and in touch with the world at all could have been unaware of Matthew’s struggles. But this doctor conspired to break his most important vows, repeatedly, sneaked through the night to meet his victim in secret. For what, a few thousand dollars? So he could feed on the vulnerability of our son.”

“The world mourns my brother,” Perry’s half-sister Madeleine Morrison said. “He was everyone’s favourite friend.”

Perry’s father John and stepmother Debbie had called for a lengthy sentence, and said Plasencia’s actions had “devastated” their family.

“How long did you possibly see supplying Matthew countless doses without his death to eventually follow?” they asked. “Did you care? Did you think?”

As well as the prison sentence, Judge Sherilyn Peace Garnett handed down two years of probation to Plasencia.

The other four people charged in connection with Perry’s death have also accepted plea deals and are due to be sentenced over the next few months.

They are: dealer Jasveen Sangha, also known as “the Ketamine Queen”, Perry’s assistant Kenneth Iwamasa, another doctor, Mark Chavez, and Erik Fleming, an associate of the actor.

Perry had struggled with addiction for years, dating back to his time on Friends, when he became one of the biggest stars of his generation playing Chandler Bing.

He starred alongside Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc and David Schwimmer for 10 seasons, from 1994 to 2004, and appeared in the reunion show in 2021.

All the news, flips and top moments from the early signing day

College football’s early signing period started Wednesday and runs until Friday. Class of 2026 high school recruits who signed have locked into the college of their choice for at least the next year.

The drama started early when Vanderbilt flipped five-star QB Jared Curtis from Georgia on Tuesday night. Defensive end Jordan Carter (No. 57 overall) was the highest-ranked uncommitted recruit. He chose Tennessee over Auburn and Georgia Tech on Wednesday. Virginia Tech was a big mover of the day, adding 11 players who were formerly in James Franklin’s class at Penn State. USC added to its top-ranked class by flipping Kayden Dixon-Wyatt from Ohio State. Texas has the most five-star signings of any team, headlined by QB Dia Bell.

If a prospect doesn’t sign a national letter of intent by Friday, the next national signing day for this cycle begins Feb. 4.

We tracked all the news, analysis and more throughout Wednesday.

Early signing day 2026 takeaways: Five-star hauls, winners and CFP hopes

College football’s early signing period opened Wednesday with much of the 2026 recruiting class committed. That added some extra drama for those teams chasing last-minute additions and flips.

Coaching changes weighed heavily on the end of this cycle with Virginia Tech adding eight commitments since James Franklin’s hiring. Auburn and Arkansas each saw movement in their classes following their coach hirings Sunday.

Here’s a look at the winners, the programs that missed out Wednesday and the questions that still loom over the 2026 cycle after more than 12 months of recruiting played out in the span of 12 hours:

Jump to: Texas’ haul | Carousel impact
CFP boost | Who has overachieved | Impact QBs

Texas’ five-star haul is impressive

A few teams landed multiple five-star prospects, but none has more than the Longhorns. The class fills needs but also has extremely talented players at impact positions.

On defense, linebacker Tyler Atkinson (No. 17 overall) has a combination of skills and production that can’t be ignored. He recorded 550 tackles in his prep career and had three double-digit sack seasons. He’s a versatile and explosive defender whether he’s rushing off the edge or in coverage. He is joined by defensive end Richard Wesley, No. 8 overall. After the Longhorns leaned some on the transfer portal this past offseason to retool their defensive line, Wesley will be a key player who projects to be versatile within their front, with the strength and heavy hands to set the edge and the ability to slide inside and expose mismatches with his quickness.

Offensively, QB Dia Bell, the sixth overall prospect, might be the most well-rounded, having been a multiyear starter and consistently playing at a high level of competition. While he is not a true dual threat, he can create second chances and be effective when asked to run. As a passer, his basketball background has helped develop his pocket movement and he has good touch on his deep ball. In running back Derrek Cooper, Texas has its future replacement for Quintrevion Wisner. Cooper’s initial impact could be limited but he brings similar attributes, with the ability to be a 1,000-yard rushing threat and rank among UT’s most productive pass catchers. Again, Texas has set itself up to replace a productive player with a prospect with arguably even greater impact ability. — Craig Haubert


Coaching changes hurt Auburn, Penn State and Oklahoma State

Traditionally, in-season firings tend to be the first domino to a class implosion. Such moves didn’t burn Florida and LSU on the 2026 recruiting trail. But amid a historic coaching carousel, the recruiting classes at Auburn, Penn State and Oklahoma State were among those that felt the fullest force of their school’s respective coaching changes in recent months.

Auburn’s latest class held firm in the weeks after the Tigers fired Hugh Freeze on Nov. 2. In fact, four of the program’s five decommitments since then occurred only after Auburn hired Alex Golesh from South Florida on Sunday. But the departures themselves were significant. Four-star safety Bralan Womack (No. 39 overall), the Tigers’ top-ranked 2026 commit, and quarterback Peyton Falzone (No. 225) each pulled their pledges on Monday. And while signatures from four-star wide receiver Jase Mathews (No. 258 overall) and a trio of ESPN 300 linebackers still give Auburn a foundation of 2026 talent, the Tigers’ incoming class lacks starpower.

Defensive tackle Danny Beale (No. 108 overall) and running back Kaydin Jones (No. 25 RB) marked Oklahoma State’s star additions in a surprisingly strong start to the 2026 cycle. Both left the Cowboys’ class between Mike Gundy’s September departure and the arrival of North Texas coach Eric Morris on Nov. 25. Following another series of decommittments over the past week-and-a-half, Morris is set to begin his rebuild in Stillwater with a thin class of early signees.

The fall recruiting misfortunes of Auburn and Oklahoma State, however, look tame next to the developments that have unfolded around Penn State’s 2026 class since mid-October.

As of Wednesday morning, only two commits remained in a Nittany Lions class that ranked 17th nationally when the school fired coach James Franklin on Oct. 12. Among the high-profile departures from Penn State since then: offensive tackle Kevin Brown (No. 78), wide receiver Davion Brown (No. 109), running back Messiah Mickens (No. 141) and longtime quarterback pledge Troy Huhn (No. 198). To add insult to injury, 10 of the Nittany Lions’ 21 total decommitments ultimately landed with Franklin at Virginia Tech, all signing with a surging Hokies 2026 Wednesday while Penn State’s coaching job still sits vacant in early December. — Eli Lederman


Which teams improved their CFP chances?

USC Trojans

35 commitments

ESPN 300 commits: 18, two five-stars

USC is getting close and just lost a game at Oregon that would have likely thrust it into the CFP in 2025. The class is loaded top to bottom, even including juco prospects. To take the next step, though, the Trojans must continue to beef up the trenches. They pulled four-star defensive tackle Jaimeon Winfield out of Texas, landed in-state defensive end Simote Katoanga and traveled to Utah to snag offensive lineman Esun Tafa. To further bolster the offensive line, the Trojans landed Keenyi Pepe out of IMG Academy. He has great size at 6-foot-7 and 320 pounds but is light on his feet as well as physical and can become a standout tackle. Five-star cornerback Elbert Hill headlines the skill-position players. Hill possesses elite speed, having been measured at over 22 mph in game play.

Michigan Wolverines

25 commitments

ESPN 300 commits: 12, one five-star

Michigan has quietly put together a very successful season, winning five games in a row prior to a loss to Ohio State despite multiple offensive injuries at running back and a true freshman QB in Bryce Underwood. This class features six players who rank in the top 10 at their respective position. Michigan bolstered its backfield by landing No. 2 running back Savion Hiter, a runner with a nice blend of size (6 feet, 200 pounds), power and speed who can also catch the ball out of the backfield. After losing two defensive linemen in the first round of the NFL draft, Michigan added several to this class, including four-stars Titan Davis, McHale Blade and Tariq Boney. Michigan has also received a commitment from five-star Carter Meadows, a rangy edge defender who can affect the QB. — Tom Luginbill


Which teams have overachieved?

Houston Cougars

18 commitments: one five-star, 17 three-stars

Coach Willie Fritz has made huge strides in his second season at Houston and recruiting has picked up as a result.

The class has been headlined for several months by five-star quarterback Keisean Henderson, the No. 1 dual-threat QB in the country. Henderson could become a program-defining prospect that thrusts the Cougars into Big 12 championship contenders for years to come. Henderson has also been a loyal commitment throughout the process despite obvious overtures by other bigger programs to flip him. He’s dynamic as a runner and a gamer as a passer.

UH’s class also features the sixth-ranked tight end in the country in Jaivion Martin. The 250-pounder is a well-rounded blocker and receiver who can play as an inline in the run game. He also competes in track and field. The Cougars have also nabbed a top-25 athlete in Paris Melvin, who could project at cornerback or wide receiver and is a dangerous return man who ran a 10.86 100m in the spring of 2025. One of the more underrated running back prospects in the class is John Hebert, a Ryan Switzer-type scatback/utility weapon. He ran a 4.54 40-yard laser timed in the spring and has posted a max speed of 21.3 mph.

This class is full of high-end three-star prospects, and perhaps no coach in the country has a better track record of developing prospects than Fritz.

SMU Mustangs

21 commitments: six four-stars

SMU is now running with the big dogs not only on the field, but in recruiting circles as well. The Mustangs have added several offensive linemen, no bigger than Sam Utu, an ESPN 300 player with tackle athleticism and guard power. The Mustangs also picked up Evan Goodwin, a massive presence at 6-7 and 320 pounds, Evan Goodwin, a massive presence at 6-7 and 320 pounds, and in-state guard Drew Evers, a thickly built and strong blocker who can latch on and control defenders. Rhett Lashley knows the trenches are what’s going to elevate the program.

Capitalizing on the rich talent base in Texas, SMU has added several in-state prospects, including SC Next 300 back Christian Rhodes. Rhodes, an explosive runner who has been recorded hitting better than 21 mph max speed in game play, also brings a physical running style at 6-1, 200 pounds. High three-star Aljour Miles II, a lengthy receiver who has good quickness and body control, is another nice in-state addition. Another receiving target with big-play potential, Jakai Anderson, was pulled out of Louisiana. Not quite as big a target, he brings a good blend of speed and elusiveness and could also be productive in the return game.

On defense, defensive end Hudson Woods shows some savvy as a pass rusher, with active hands and good bend. Linebacker Kenneth Goodwin out of California is a versatile, physical defender who can rush the passer.

Auburn Tigers

12 commitments: six ESPN 300 prospects, eight total four-stars

Despite the firing of coach Hugh Freeze and some late defectors, this class still has major talent upgrades committed, particularly on defense. The class is not large, but it is stacked with overall top-end talent. There are four players ranked within the top 11 players in the country at their respective position and two within the top three.

Adam Balogoun-Ali is the country’s No. 1 inside linebacker and also happens to have significant growth upside with his lengthy frame. He can play inside and on the outside as an edge rusher and excels in space due to his speed and agility. The Tigers also have a commitment from the No. 3 inside linebacker in the class, Shadarius Toodle. Toodle is just a step behind Balogoun-Ali in terms of overall speed and is a downhill gap plugger in the middle of the field.

New head coach Alex Golesh has a good foundation to head into the dead period with and attack the transfer portal in January for more additions. — Luginbill


These 2026 QBs could start early

Jake Fette, Arizona State Sun Devils: Assuming Sam Leavitt goes in the portal, Fette, the No. 4-ranked dual threat, brings a lot of great traits to the Sun Devils offense. He’s super athletic and mobile, with the field vision to keep his eyes downfield while on the move. Fette is very similar to Leavitt in stressing defenses with his arms and legs. Fette also has good touch and anticipation on short to midrange throws. Coach Kenny Dillingham will challenge defenses schematically with a lot of shifts, motions and backfield action that will maximize Fette’s dynamic skill set in and outside the pocket.

Oscar Rios, Arizona Wildcats: Rios is the Wildcats’ highest-rated pocket passer signee in the ESPN 300 era. How immediate the impact depends on whether Noah Fifita returns for the 2026 season. If Fifita chooses to return, Rios could redshirt as a true freshman and be the favorite to become the starter in 2027. Rios’ quick release and great arm strength should lead to big numbers under coordinator Seth Doege in Tucson. — Billy Tucker
