The James Webb Space Telescope has spotted the earliest known black hole in the universe, and astronomers think even earlier ones could have swarmed the young cosmos.

The James Webb Space Telescope (JWST), whose powerful cameras allow it to peer back in time to the earliest stages of the universe, discovered the supermassive black hole, which has a mass of 10 million times that of the sun, at the center of a baby galaxy 570 million years after the universe began.

The cosmic monster could be just one of countless black holes that gorged themselves to ever-larger sizes during the cosmic dawn — the period starting about 100 million years after the Big Bang when the young universe glowed for a billion years. Astronomers aren’t sure why there were so many of these black holes or how they got so big. The researchers who found the latest black hole published their findings March 15 on the preprint server arXiv (opens in new tab) , but the research has not been peer-reviewed yet.

“This is the first one that we’re finding at this redshift [point in time after the Big Bang], but there should be many of them,” lead study author Rebecca Larson (opens in new tab) , an astrophysicist at the University of Texas at Austin, told Live Science. “We do expect that this black hole didn’t just form [recently], so there should be more that are younger and existed earlier on in the universe. We’re just starting to be able to study this time in cosmic history this way with the JWST, and I’m excited for us to find more of them.”

Black holes are born from the collapse of giant stars and grow by ceaselessly gorging on gas, dust, stars and other black holes. For some of the gluttonous space-time ruptures, friction causes the material spiraling into their maws to heat up, and they emit light that can be detected by telescopes — turning them into so-called active galactic nuclei (AGN). The most extreme AGN are quasars, supermassive black holes that are billions of times heavier than the sun and shed their gaseous cocoons with light blasts trillions of times more luminous than the brightest stars.

Because light travels at a fixed speed through the vacuum of space, the deeper that scientists look into the universe, the more remote light they intercept and the further back in time they see. To spot the black hole, the astronomers scanned the sky with two infrared cameras — the JWST’s Mid-Infrared Instrument (MIRI) and Near Infrared Camera — and used the cameras’ built-in spectrographs to break down the light into its component frequencies. 

By deconstructing these faint glimmers sent from the universe’s earliest years, they found an unexpected spike among the frequencies contained within the light — a key sign that the hot material around a black hole was beaming out faint traces of radiation across the universe.

How black holes formed so suddenly across our young comos remains a mystery. Astronomers are still on the hunt for even younger, hypothesized “primordial” black holes,  which came into being very soon after — or, according to some theories, even before — the Big Bang. But so far, they remain elusive. RELATED STORIES— James Webb Telescope spots galaxies from the dawn of time that are so massive they ‘shouldn’t exist’

—What’s the biggest black hole in the universe?

There are two leading theories for how so many black holes grew so quickly after the Big Bang: that they are the remains of giant stars that formed far faster than the ones we know today, or that billowing clouds of incredibly dense gas collapsed suddenly to form the all-consuming singularities in space-time.

“The direct collapse method would have to start with a larger amount of matter in the galaxy directly collapsing into a black hole,” Larson said. “It’s less likely but it would take less time, and there hasn’t been that much time at the point we observed it.”

More likely, it is a so-called Population III Star — a category of hypothesized stars that were the first to ever exist in the universe and were made of just hydrogen and helium — that exploded and left behind a black hole around 200 million years after the Big Bang and “then accreted a lot of material pretty quickly and occasionally at a faster-than-stable rate,” to swell up to the size that researchers observed, Larson explained.

The researchers will now begin working alongside the team that built MIRI to scan for an even stronger signature of the light from the distant galaxy. Those emissions could contain further clues about how the mysterious black hole formed at the galaxy’s center.

Hard-throwing rookie Misiorowski going to ASG

Hard-throwing rookie Misiorowski going to ASG

Hard-throwing rookie Jacob Misiorowski is a National League All-Star replacement, giving the Milwaukee Brewers right-hander a chance to break Paul Skenes‘ record for the fewest big league appearances before playing in the Midsummer Classic.

Misiorowski was named Friday night to replace Chicago Cubs lefty Matthew Boyd, who will be unavailable for the All-Star Game on Tuesday night in Atlanta because he is scheduled to start Saturday at the New York Yankees.

The 23-year-old Misiorowski has made just five starts for the Brewers, going 4-1 with a 2.81 ERA while averaging 99.3 mph on his fastball, with 89 pitches that have reached 100 mph.

If he pitches at Truist Park, Misiorowski will make it consecutive years for a player to set the mark for fewest big league games before an All-Star showing.

Skenes, the Pittsburgh Pirates right-hander getting ready for his second All-Star appearance, had made 11 starts in the majors when he was chosen as the NL starter for last year’s All-Star Game at Texas. He pitched a scoreless inning.

“I’m speechless,” said a teary-eyed Misiorowski, who said he was given the news a few minutes before the Brewers’ 8-3 victory over Washington. “It’s awesome. It’s very unexpected and it’s an honor.”

Misiorowski is the 30th first-time All-Star and 16th replacement this year. There are now 80 total All-Stars.

“He’s impressive. He’s got some of the best stuff in the game right now, even though he’s a young pitcher,” said Yankees slugger Aaron Judge, who is a starting AL outfielder for his seventh All-Star nod. “He’s going to be a special pitcher in this game for a long time so I think he deserved it and it’s going be pretty cool for him and his family.”

Carlos Rodón, Carlos Estévez and Casey Mize were named replacement pitchers on the AL roster.

The New York Yankees‘ Rodón, an All-Star for the third time in five seasons, will replace teammate Max Fried for Tuesday’s game in Atlanta. Fried will be unavailable because he is scheduled to start Saturday against the Chicago Cubs.

In his final start before the All-Star game, Rodón allowed four hits and struck out eight in eight innings in an 11-0 victory over the Cubs.

“This one’s a little special for me,” said Rodón, an All-Star in 2021 and ’22 who was 3-8 in his first season with the Yankees two years ago before rebounding. “I wasn’t good when I first got here, and I just wanted to prove that I wasn’t to going to give up and just put my best foot forward and try to win as many games as I can.”

The Kansas City Royals‘ Estévez replaces Texas’ Jacob deGrom, who is scheduled to start at Houston on Saturday night. Estévez was a 2023 All-Star when he was with the Los Angeles Angels.

Mize takes the spot held by Boston‘s Garrett Crochet, who is scheduled to start Saturday against Tampa Bay. Mize gives the Tigers six All-Stars, most of any team and tied for the franchise record.

Royals third baseman Maikel Garcia will replace Tampa Bay‘s Brandon Lowe, who went on the injured list with left oblique tightness. The additions of Estévez and Garcia give the Royals four All-Stars, matching their 2024 total.

The Seattle Mariners announced center fielder Julio Rodríguez will not participate, and he was replaced by teammate Randy Arozarena. Rodríguez had been voted onto the AL roster via the players’ ballot. The Mariners, who have five All-Stars, said Rodríguez will use the break to “recuperate, rest and prepare for the second half.”

Arozarena is an All-Star for the second time. He started in left field for the AL two years ago, when he was with Tampa Bay. Arozarena was the runner-up to Vladimir Guerrero Jr. in the 2023 Home Run Derby.

Rays right-hander Drew Rasmussen, a first-time All-Star, is replacing Angels left-hander Yusei Kikuchi, who is scheduled to start Saturday night at Arizona. Rasmussen is 7-5 with a 2.82 ERA in 18 starts.

San Diego added a third NL All-Star reliever in lefty Adrián Morejón, who replaces Philadelphia starter Zack Wheeler. The Phillies’ right-hander is scheduled to start at San Diego on Saturday night. Morejón entered the weekend with a 1.71 ERA in 45 appearances.

M's Raleigh hits 2 more HRs, brings total to 38

DETROIT — Cal Raleigh hit his 37th and 38th home runs in Seattle‘s 12-3 victory over Detroit on Friday night to move within one of Barry Bonds’ 2001 major league record for homers before the All-Star break.

Raleigh hit a solo homer off former teammate Tyler Holton in the eighth to tie the American League record of 37 before the All-Star break set by Reggie Jackson in 1969 and matched by Chris Davis in 2013.

“[Holton] and I are really good friends, and I’ve caught a lot of his pitches,” said Raleigh, who was in the lineup as the designated hitter instead of at catcher. “I don’t think that helped much, but I’m sure he’s not very happy with me.”

Raleigh hit a grand slam off Brant Hurter in the ninth.

“I didn’t even know it was a record until just now,” Raleigh said. “I don’t have words for it, I guess. I’m just very grateful and thankful.”

It was Raleigh’s eighth multihomer game this season, tying Jackson (also in 1969) for the most such games before the All-Star break in MLB history, according to ESPN Research. He also tied Ken Griffey Jr. for the most multihomer games in Mariners franchise history.

Seattle has two games left in Detroit before the break.

“Cal Raleigh … this is just unbelievable,” Mariners manager Dan Wilson said. “He’s already set the AL record and now he’s only one short of Barry. There are two games, so who knows?”

Raleigh hit 10 homers in March and April, 12 in May, 11 in June and has five in July.

“This is a very boring comment, but baseball is all about consistency,” Wilson said. “This hasn’t been one hot streak, he’s doing this month after month. That says everything.”
