NASA reveals ‘incredible’ findings from asteroid that could explain origins of life on Earth
NASA has revealed its “incredible” findings from a sample that was scooped up from the surface of an asteroid and delivered to Earth by spacecraft.
The sample, ancient black dust and chunks, was collected from the carbon-rich asteroid named Bennu, almost 60 million miles away.
It is the largest ever returned to Earth.
NASA‘s Osiris-Rex spacecraft collected the samples three years ago and then dropped them off sealed in a capsule during a flyby of Earth last month.

Scientists hope it can shed light on the origin of the solar system and of life on Earth.
An Osiris-Rex sample analyst, Daniel Glavin, said during a news conference to reveal the material that the sample was “loaded with organics”.
“This is just incredible material,” he said.
“This stuff is an astrobiologist’s dream, I just can’t wait to get at it.”
The scientists have been investigating whether asteroids like Bennu seeded the Earth with pre-biotic chemicals.
Mr Glavin said: “We’re going to learn so much about the origin of the solar system, the evolution and potentially how even life started here on Earth.”
Dante Lauretta, Osiris-Rex principal investigator, said the different sized stones contained in the sample would provide invaluable information for scientists.
‘Something from space we have never seen in our laboratories’
“Something like that would not make it to the surface of the Earth as a meteorite,” he said.
“So to have something from space that we have never seen in our laboratories, there is nothing more exciting.”
Bennu is considered the most dangerous asteroid in the Solar System – although NASA has estimated its chances of actually hitting Earth in 2182 are remote, at just one in 2,700, or 0.037%.
Lori Glaze, director of the agency’s planetary science division, explained how the latest sample could help protect our planet from a catastrophic impact with a space object.
She said the mission allowed NASA to measure a small force created by the sun’s heat and an asteroid’s rotation – explaining this force was “really important for helping us to predict when a particular asteroid might be dangerous”.

“What we really want to know is if an asteroid is going to cross over Earth’s orbit at the same time that we are in that place, and we want to not be in that place when an asteroid comes by,” she said.
Administrator Bill Nelson – explained the discovery was unprecedented.
“At nearly 5% carbon by weight, carbon being the central element of life, far exceeding our goal of 60g, this is the biggest carbon-rich asteroid sample ever returned to earth,” he said.
Carbon and water molecules are “exactly the kind of material that we wanted to find”, Mr Nelson added.
“They are going to help us determine the origin of elements that could have led to life.”

Sky News Science Correspondent Thomas Moore explains what it all means.
So much material has been brought back from asteroid Bennu that it has spilled out of the collection cannister.
NASA scientists still haven’t got inside – they’ve been carefully sweeping together their “bonus sample” to make sure it’s not wasted.
It’s slowed them down, so they’ve only had time to do a basic analysis of the material in the fortnight or so since the capsule parachuted down to Utah’s western desert last month.
Results so far show that it is rich in carbon, an essential element for the organic molecules that are the building blocks of life.
And stunning high magnification images taken with an electron microscope reveal fibrous clay particles that contain water.
That adds to evidence that asteroids bombarding planet Earth billions of years ago brought water that formed the oceans, and also the seeds of life.
But this is just the start.
They now need to work out exactly what chemicals are in the sample.
Analysis of material brought back from another asteroid called Ryugu by a Japanese spacecraft revealed dozens of organic compounds, including amino acids that form proteins.
There was only a tiny amount of material brought back from Ryugu and scientists haven’t yet been able to detect any of the chemical ingredients for making RNA and DNA, the genetic codes of life on Earth.
But there is much more material brought back from Bennu.
Just over a quarter of the material will be analysed over the next two years by scientists at laboratories around the world, including a team at the Natural History Museum in London.
The rest will be preserved for future analysis, as NASA says, by scientists who haven’t been born yet using techniques that can only be imagined.
That might tell us more about our origins. But perhaps also give clues to how our planet formed.
Bennu is a window into the early days of the solar system, 4.5 billion years ago. It’s likely to have changed very little since it was formed from loose rubble orbiting between Mars and Jupiter.
The planets would have been formed from the same material. But Bennu’s material is pristine, unchanged by the intense heat and pressure involved in making a planet.
You can sense the excitement of the scientists. They’ve had so many questions about our place in the Universe.
And with the Bennu sample they might start getting some answers.

Bodies of two more Israeli hostages handed over by Hamas – but uncertainty over missing remains
The bodies of two more Israeli hostages have been handed over to the Red Cross by Hamas – but uncertainty still hangs over the fate of the missing remains of others.
Under the ceasefire agreement, all remaining 48 hostages, dead and alive, were supposed to be returned by this Monday.
So far, only the 20 living hostages have been returned, as well as seven dead hostages, according to Israel’s count, with two further bodies still being verified.
Just hours after today’s handover, the Israeli military said a tenth body previously turned over was not that of a hostage – and the confusion added to tensions over the fragile truce that has paused the two-year war.
What has Hamas said?
Hamas has previously said recovering the remaining bodies could take time, as not all burial sites are known.
Its armed wing put out a statement on Wednesday, saying it has returned all the bodies it could reasonably recover, but would require special equipment to hand over the remaining ones.
Meanwhile, the Gaza Health Ministry said it received 45 more bodies of Palestinians from Israel, another step in the implementation of the ceasefire agreement.

That brings to 90 the total number of bodies returned to Gaza for burial. The forensics team examining the remains claimed they showed signs of mistreatment.
Trump issues warning
The return of all the hostages is a key pillar of the deal agreed to by Israel and Hamas, heralded by US President Donald Trump as having brought “peace in the Middle East”.
Israel – which has freed around 2,000 Palestinian prisoners and detainees as part of the peace deal – had already threatened to keep the Rafah crossing between Gaza and Egypt closed on Wednesday, and limit aid entering Gaza, due to Hamas not returning all of the dead.
And in an interview with CNN on Wednesday, Mr Trump warned that Israel could resume the war if he feels Hamas is not upholding its end of the agreement.
“Israel will return to those streets as soon as I say the word,” he said.

Analysis: There is a catch to Trump’s Gaza peace deal
Since the October 7 Hamas attacks on Israel in 2023 – in which around 1,200 people were killed and 251 taken hostage – the two sides have been at war.
Nearly 68,000 Palestinians have been killed since Israel’s subsequent offensive, according to the Health Ministry, which is part of the Hamas-run government in Gaza.
The ministry maintains detailed casualty records that are seen as generally reliable by UN agencies and independent experts – though the ministry does not say how many of those killed are combatants.

Similar incident in previous ceasefire
This is not the first time Hamas has returned a wrong body to Israel.
During a previous ceasefire, the group said it handed over the bodies of Shiri Bibas and her two sons, but testing in February 2025 showed that one of the bodies returned was identified as a Palestinian woman. Ms Bibas’ body was returned a day later.
Meanwhile, Hamas spokesperson Hazem Kassem accused Israel of violating the deal with shootings on Tuesday in eastern Gaza City and the southern city of Rafah.

Israel’s defence minister, Israel Katz, said the military is operating along the deployment lines troops withdrew to under the deal, and he warned that anyone approaching the lines will be targeted, as happened on Tuesday with several militants.
Aid trickling in
The World Food Programme said its trucks began arriving in Gaza after the entrance of humanitarian aid was paused for two days due to the exchange on Monday and a Jewish holiday on Tuesday.
The timing of the scaled-up deliveries – which are also part of the ceasefire deal – had been called into question after Israel said on Tuesday that it would cut the number of trucks allowed into Gaza, saying Hamas was too slow to return the hostages’ bodies.

Abeer Etefa, spokesperson for the World Food Programme, lauded the trucks’ passage but said the situation remained unpredictable.
“We’re hopeful that access will improve in the coming days,” she said.
The Egyptian Red Crescent said 400 trucks carrying food, fuel and medical supplies were bound for Gaza on Wednesday.
Fifteen UK charities have launched a fresh appeal for donations to Gaza to address “catastrophic levels of need” in the devastated region.
The charities make up the Disasters Emergency Committee (DEC), which has been raising millions for Gaza – where tens of thousands have been killed over the past two years of war – and the wider Middle East.
After the initial stage of a much-sought ceasefire deal aimed at ending the conflict in Gaza was agreed on by Israel and Hamas, aid has begun to trickle into the devastated region again.
According to the DEC, its charities and local partners have been scaling up their work in the Gaza Strip since the agreement took effect last week.

It said lorries carrying food and other aid began to enter Gaza on Sunday, with the British Red Cross and Plan International UK among those confirming supplies had made it in.
After raising more than £50m since the Middle East Humanitarian Appeal was launched last October, the DEC is renewing calls for donations, saying £10 could provide blankets for two people, while £50 could provide emergency food for five families for one week.

As goods are returning to Gaza’s markets, the DEC said, they are increasing cash assistance to help people buy essentials as they become more affordable.
They’re also distributing clean water, medicine, food, and nutrition support.
On its website, the DEC pointed to how famine was declared in Gaza City in August as it appealed for funds saying: “Your support can save lives.”

Donald Trump has refused to say if the CIA has the authority to assassinate Venezuela’s president, after approving covert operations in the country to tackle alleged drug trafficking.
The classified decision, first revealed by The New York Times, marks a significant escalation in efforts to pressure President Nicolas Maduro‘s regime.
Mr Trump said large amounts of drugs were entering the US from Venezuela, much of it trafficked by sea.
“We are looking at land now, because we’ve got the sea very well under control,” he said.
When asked why the coastguard wasn’t asked to intercept suspected drug trafficking boats, which has been a longstanding US practice, Mr Trump said the approach had been ineffective.
“I think Venezuela is feeling heat,” he said.
He declined to answer whether the CIA has the authority to execute Mr Maduro.
The US has offered a $50m (£37m) reward for information leading to his arrest, accusing him of connections to drug trafficking and criminal organisations – claims he denies.

US targets ‘drug boats’
Mr Trump also alleged Venezuela had sent a significant number of prisoners, including individuals from mental health facilities, into the US, though he did not specify the border through which they reportedly entered.
On Tuesday, he announced America had targeted a small boat suspected of drug trafficking in waters off the Venezuelan coast, resulting in the deaths of six people.
According to the president’s post on social media, all those killed were aboard the vessel.

The incident marked the fifth such fatal strike in the Caribbean, as the Trump administration continues to classify suspected drug traffickers as unlawful combatants to be confronted with military force.
War secretary Pete Hegseth authorised the strike, according to Mr Trump, who released a video of the operation.
The black-and-white footage showed a small boat seemingly stationary on the water. It is struck by a projectile from above and explodes, then drifts while burning for several seconds.
Mr Trump said the “lethal kinetic strike” was in international waters and targeted a boat travelling along a well-known smuggling route.
There has also been a significant increase in US military presence in the southern Caribbean, with at least eight warships, a submarine, and F-35 jets stationed in Puerto Rico.
