Interstellar Comet 3I/ATLAS is almost as old as the universe itself
Join Our Community of Science Lovers!
The latest interstellar visitor to be discovered in our solar system was born somewhere in the universe that was nothing like our home and, according to a new study, a time long before the solar system even formed—in the infancy of the cosmos.
Spotted in 2025, 3I/ATLAS is the third interstellar comet that astronomers have identified flying through our solar system, after 1I/ʻOumuamua and 2I/Borisov. Since then researchers have used the space-based James Webb Space Telescope (JWST) and the ground-based Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to study the gas spouting out from 3I/ATLAS as the sun’s heat has burned up its icy insides. Chemical isotopes contained in the gas reveal details of the comet’s murky history—and a new study published in Nature (after it was posted online as a preprint in March) helps further color in that origin story.
Using carbon isotopes in the comet to estimate its age, the authors believe it may be even more ancient than earlier estimates had suggested—as old as 12 billion years. That’s far older than our own solar system, which is 4.5 billion years old, and just less than two billion years younger than the universe itself.

The study also shows that 3I/ATLAS came from a much colder region of its own solar system than any of the comets we see in our own. The comet contains far more heavy hydrogen—in the form of an isotope called deuterium, which has one neutron and one proton—than any local space rock, a quality that tends to point to colder environs. The finding jibes with other recent research, and astronomers are increasingly speculating that our solar system might be the oddball—and that the comets we’ve been studying for centuries have been unlike most in the universe.
It’s thanks to cutting-edge telescopes like ALMA and JWST that we’ve spotted these first three interstellar objects. And with the Vera C. Rubin Observatory in Chile now beginning a decade-long sky survey, more such discoveries are likely to follow, says Cyrielle Opitom, an astronomer at the University of Edinburgh in Scotland and a co-author of the new study. “We hope they will be as exciting as 3I/ATLAS,” she says. These vagrant rocks could soon tell us far more about what lies at the universe’s outer reaches—and perhaps how weird we really are.

SubscribeBadenoch blasts 'moaning' female Labour MPs over Burnham jobs 'quota'
Kemi Badenoch has told Labour women to earn a job in Andy Burnham's Cabinet instead of demanding they are handed jobs because of their gender.
The Tory leader lashed out today amid reports that female MPs are demanding the de-facto new prime minister introduce a 50:50 gender split 'quota' in his government.
Amid reports that former foreign secretary David Miliband is being lined up to return to the role, possibly with his brother Ed as Chancellor, one female minister also complained that Burnham could not have 'more Milibands than women' in the top posts.
But in a scathing article in the Times today Mrs Badenoch told them to 'stop moaning' and get chosen on merit instead of retreating into 'more of the failed identity politics that is holding back our country'.
'There are many, many reasons why you shouldn't have any Milibands in the cabinet,' she said.
'But complaining that the boys haven't given them the right jobs or that the boys are taking all the jobs, just shows that Labour's women still don't get it.'
The idea of quotas was also attacked by Baroness Jacqui Smith, Labour's Skills Minister.
Asked by Times Radio if Mr Burnham should reserve jobs for women, she said: 'No, I think what Andy Burnham should be doing is building the very best team around him to change this country.'
A letter written by the Women's Parliamentary Labour Party has called on Mr Burnham to ensure a 50:50 split between men and women in government jobs

But Mrs Badenoch told them to pipe down and get chosen on merit instead of retreating into 'more of the failed identity politics that is holding back our country'
A letter written by the Women's Parliamentary Labour Party and seen by the BBC has called on Mr Burnham to ensure a 50:50 split between men and women in government jobs after he succeeds Sir Keir Starmer.
'We are asking you to demonstrate this change from day one and address the toxicity and misogyny within our own party and government,' it said.
Labour has never had a female leader, while the Conservatives have had three, and Mrs Badenoch urged the government to follow its meritocratic example.
'If you run a meritocracy, then you do not have to worry about jobs for the boys,' she wrote.
'Every woman who is a Conservative MP, every woman who has ever won the leadership, has had to fight to get where she is.
'By contrast, Labour women are demanding guarantees from Burnham. But the truth is he doesn't have to give any guarantees.
'If none of Labour's women are prepared to get their hands dirty and challenge him for the leadership, their demands are toothless.'
'In fact, it's quite revealing that the women's parliamentary Labour Party has written to Burnham asking him to commit himself to at least 50 per cent female ministers.
'This has nothing to do with meritocracy. It is yet more of the failed identity politics that is holding back our country.'
Venezuela Fury and Noah Price subsidising their life by livestreaming
Venezuela Fury and her husband Noah Price look to be making their own way in the world by raking it in from their lucrative social media accounts.
The influencer daughter of Tyson and Paris Fury, 16, has become an internet sensation after tying the knot with her husband Noah, 19, earlier this year.
Since getting married and moving in together the couple have been earning thousands of pounds a month, livestreaming their life as newlyweds in their static caravan in the East Riding of Yorkshire.
And fans can't get enough of their regular life updates on TikTok and Kick, which have proved to be very profitable for the pair.
They look to be supporting themselves after Noah denied that he was given £5million by Venezuela's family as a wedding gift.
Despite his wife's huge family wealth, an estimated combined £160 million, Noah recently told his Kick followers that he 'pays for everything' for the couple.
Making light of the claims about Venezuela's millionaire financial status, Noah said: 'I actually pay for everything unfortunately. You'd expect the millionaire to pay for it wouldn't you.'

Venezuela then asked their fans: 'Do you think I am a millionaire?'
Noah joked: 'She isn't a secret millionaire guys', before she broke into song and sang: 'But I live like a millionaire!'
But it seems according to estimated calculations from their social media work, Noah and Venezuela can more than afford to support themselves.
Noah has been livestreaming on platforms such as Kick and TikTok, where viewers can send paid gifts or donations.
He was previously encouraging viewers to send gifts on his honeymoon during livestreams, suggesting this is one revenue stream.
Both Noah and Venezuela have built substantial followings on Instagram and TikTok. They can potentially earn money through sponsored posts, brand collaborations, affiliate links and creator payouts.
Kick allows its creators to take home 95 per cent of the £4.99 subscription cost that fans pay.
Streamers keep 100 per cent of direct tips and donations, minus minor standard payment processing fees.
It is unclear how many subscribers Noah currently has because this information is hidden, but he does have 7,200 followers which is publicly viewable.
An industry insider has suggested Noah is making around £400 per video on TikTok, while Venezuela is likely to make £2,000 due to her following count of 1.3 million.

In one video on their honeymoon, Noah asked his followers if they'd give them some more gifts now that they were married.
In a TikTok live viewed by 20,000 he said: 'Keep liking our videos people, keep sending gifts.'
After saying thank you to several of his followers he joked they should stick around on the livestream and 'watch Venezuela punch me in the mouth'.
The other half of the honeymooning couple said: 'I am, honestly!'
Noah previously confirmed that the pair don't share their finances after they were asked whether they have a shared bank account.
'She earns her money, I earn mine,' said Noah, as Venezuela joked: 'Yeah, what you gonna do about it.'
Noah went on to debunk the rumour that Tyson gave him £5million when he tied the knot with his daughter as he insisted: 'No Tyson did not give me £5million'.
Meanwhile Venezuela is being eyed up by executives for a fly on the wall TV series.

Boasting 1.3 million TikTok followers, Venezuela is already entertaining fans with her honest musings and candid moments, from cooking to kitting out her and Noah's static caravan home.
And following the success of the Netflix series At Home With The Furys, it is no wonder bosses are wanting to draw on the Fury popularity.
A TV insider said: 'The couple are not A-list celebrities but everyone has become obsessed with their love story.
'People are genuinely intrigued by them. Whether it’s the fact they have married so young, Venezuela’s famous family or their gypsy lifestyle, they have the ‘X factor'.
'Several TV executives think a proper fly-on-the-wall series following their lives as newlyweds in the gypsy community would be fascinating,' they told The Sun.
It is thought Netflix would be likely to produce the series due to their already established relationship with the Furys.
Venezuela's representatives told The Daily Mail: 'We have many offers on the table regarding Venezuela which we are discussing.'
