Astronomers have observed what is currently the oldest known “dead” galaxy, thanks to the James Webb Space Telescope.
The discovery by the University of Cambridge reveals a galaxy that stopped forming stars more than 13 billion years ago, when the universe was barely 700 million years old.
“A galaxy is dead when it no longer forms stars,” the study's co-author Dr Francesco D’Eugenio told The National.
“This is the earliest example known of a dead galaxy millions of years ago, when the universe was very young and cold gas [from which stars are born] was abundant in and around galaxies”.
“It is surprising to see a galaxy that is not forming stars, during an epoch when other galaxies were bursting with star formation.”
The study, detailed in Nature, explored how star formation ceases and the effects on galaxy evolution.
This discovery not only challenges previous models based on the modern universe but also opens new avenues for understanding the early universe's complexities.
The researchers found this celestial anomaly in a tiny fraction of the Goods South Field, highlighting it in a false-colour JWST image.
The galaxy in question appears to have undergone a brief but intense phase of star formation before abruptly going quiet.
“The first few hundred million years of the universe were a very active phase, with lots of gas clouds collapsing to form new stars,” said lead author Tobias Looser, from the Kavli Institute for Cosmology at the University of Cambridge.
Theories abound as to why star formation ceases in galaxies, ranging from the influence of supermassive black holes to the rapid consumption of gas necessary for creating new stars.
“Stoppage of star formation is a crucial stage of galaxy evolution; in addition, understanding when and how galaxies stop forming stars is a crucial step towards understanding how star formation and supermassive black hole accretion work,” Dr D’Eugenio said.
However, this particular galaxy's early and abrupt transition to dormancy is unique, suggesting that models based on more recent periods in the universe's history may need re-evaluation.
“We’re not sure if any of those scenarios can explain what we’ve now seen with Webb,” said co-author Roberto Maiolino, professor of experimental astrophysics at the Kavli Institute for Cosmology.
This ancient galaxy's discovery was made possible by the JWST Advanced Deep Extragalactic Survey (Jades), which revealed that its star-forming period lasted between 30 million and 90 million years before halting suddenly 10 million to 20 million years before its observation by the JWST.
“We simply did not expect to find dead galaxies so early; this means that our theories – which are rooted in observations of the nearby universe – do not quite capture the higher energy of processes in the early Universe,” Dr D’Eugenio said.
Despite its current “dead” status, astronomers do not discount the possibility that the galaxy could have reignited its star-forming engine in the billions of years since it was last observed.
“All the things that enable us to exist – the oxygen and nitrogen in the air we breath, the carbon in our food and fuel, the iron in our tools, the calcium in our bones – all these elements were synthesised in the core of stars,” Dr D'Eugenio said.
“I find it incredibly uniting to think that the matter that makes you and I, once, may have been in the core of the same star. Studying the earliest galaxies is a bit [like] studying our common origins”.
The search is now on for more galaxies from the early universe to better understand the mechanisms behind the cessation of star formation, which could reveal that galaxies might “die” and then spring back to life, adding a new layer of complexity to our cosmic understanding.

Salah in numbers
€39 million: Liverpool agreed a fee, including add-ons, in the region of €39m (nearly Dh176m) to sign Salah from Roma last year. The exchange rate at the time meant that cost the Reds £34.3m - a bargain given his performances since.
13: The 25-year-old player was not a complete stranger to the Premier League when he arrived at Liverpool this summer. However, during his previous stint at Chelsea, he made just 13 Premier League appearances, seven of which were off the bench, and scored only twice.
57: It was in the 57th minute of his Liverpool bow when Salah opened his account for the Reds in the 3-3 draw with Watford back in August. The Egyptian prodded the ball over the line from close range after latching onto Roberto Firmino's attempted lob.
7: Salah's best scoring streak of the season occurred between an FA Cup tie against West Brom on January 27 and a Premier League win over Newcastle on March 3. He scored for seven games running in all competitions and struck twice against Tottenham.
3: This season Salah became the first player in Premier League history to win the player of the month award three times during a term. He was voted as the division's best player in November, February and March.
40: Salah joined Roger Hunt and Ian Rush as the only players in Liverpool's history to have scored 40 times in a single season when he headed home against Bournemouth at Anfield earlier this month.
30: The goal against Bournemouth ensured the Egyptian achieved another milestone in becoming the first African player to score 30 times across one Premier League campaign.
8: As well as his fine form in England, Salah has also scored eight times in the tournament phase of this season's Champions League. Only Real Madrid's Cristiano Ronaldo, with 15 to his credit, has found the net more often in the group stages and knockout rounds of Europe's premier club competition.

Volunteers offer workers a lifeline
Community volunteers have swung into action delivering food packages and toiletries to the men.
When provisions are distributed, the men line up in long queues for packets of rice, flour, sugar, salt, pulses, milk, biscuits, shaving kits, soap and telecom cards.
Volunteers from St Mary’s Catholic Church said some workers came to the church to pray for their families and ask for assistance.
Boxes packed with essential food items were distributed to workers in the Dubai Investments Park and Ras Al Khaimah camps last week. Workers at the Sonapur camp asked for Dh1,600 towards their gas bill.
“Especially in this year of tolerance we consider ourselves privileged to be able to lend a helping hand to our needy brothers in the Actco camp," Father Lennie Connully, parish priest of St Mary’s.
Workers spoke of their helplessness, seeing children’s marriages cancelled because of lack of money going home. Others told of their misery of being unable to return home when a parent died.
“More than daily food, they are worried about not sending money home for their family,” said Kusum Dutta, a volunteer who works with the Indian consulate.
Red flags
- Promises of high, fixed or 'guaranteed' returns.
- Unregulated structured products or complex investments often used to bypass traditional safeguards.
- Lack of clear information, vague language, no access to audited financials.
- Overseas companies targeting investors in other jurisdictions - this can make legal recovery difficult.
- Hard-selling tactics - creating urgency, offering 'exclusive' deals.
