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.

IDF admits mistakenly identifying Gaza aid workers as threat – after video of attack showed ambulances were marked

IDF admits mistakenly identifying Gaza aid workers as threat - after video of attack showed ambulances were marked

The IDF has admitted to mistakenly identifying a convoy of aid workers as a threat – following the emergence of a video which proved their ambulances were clearly marked when Israeli troops opened fire on them.

The bodies of 15 aid workers – including eight medics working for the Palestine Red Crescent Society (PRCS) – were found in a “mass grave” after the incident, according to the head of the UN Office for Coordination of Humanitarian Affairs Jonathan Whittall.

The Israeli military originally claimed an investigation found the vehicles did not have any headlights or emergency signals and were therefore targeted as they looked “suspicious”.

But video footage obtained by the PRCS, and verified by Sky News, showed the ambulances and a fire vehicle clearly marked with flashing red lights.

In a briefing from the IDF, they said the ambulances arrived in the Tel Sultan neighbourhood in Rafah shortly after a Hamas police vehicle drove through.

An IDF surveillance aircraft was watching the movement of the ambulances and notified troops on the ground. The IDF said it will not be releasing that footage.

When the ambulances arrived, the soldiers opened fire, thinking the medics were a threat, according to the IDF.

The soldiers were surprised by the convoy stopping on the road and several people getting out quickly and running, the IDF claimed, adding the soldiers were unaware the suspects were in fact unarmed medics.

An Israeli military official would not say how far away troops were when they fired on the vehicles.

The IDF acknowledged that its statement claiming that the ambulances had their lights off was incorrect, and was based on the testimony from the soldiers in the incident.

The newly emerged video footage showed that the ambulances were clearly identifiable and had their lights on, the IDF said.

The IDF added that there will be a re-investigation to look into this discrepancy.

Addressing the fact the aid workers’ bodies were buried in a mass grave, the IDF said in its briefing this is an approved and regular practice to prevent wild dogs and other animals from eating the corpses.

The IDF could not explain why the ambulances were also buried.

The IDF said six of the 15 people killed were linked to Hamas, but revealed no detail to support the claim.

Bodies of aid workers found in Gaza

The newly emerged footage of the incident was discovered on a phone belonging to one of the workers who was killed, PRCS president Dr Younis Al Khatib said.

“His phone was found with his body and he recorded the whole event,” he said. “His last words before being shot, ‘Forgive me, mom. I just wanted to help people. I wanted to save lives’.”

Sky News used an aftermath video and satellite imagery to verify the location and timing of the newly emerged footage of the incident.

It was filmed on 23 March north of Rafah and shows a convoy of marked ambulances and a fire-fighting vehicle travelling south along a road towards the city centre. All the vehicles visible in the convoy have their flashing lights on.

The footage was filmed early in the morning, with a satellite image seen by Sky News taken at 9.48am local time on the same day showing a group of vehicles bunched together off the road.

Volodymyr Zelenskyy takes swipe at US over 'weak' comment on Russian attack - as Ukrainian drones strike factory

Ukrainian President Volodymyr Zelenskyy has hit out at the US over its “weak” response to lethal Russian attacks on his hometown on Friday.

President Zelenskyy posted a lengthy and emotional statement on X about Russia’s strikes on Kryvyi Rih, which killed 19 people.

Meanwhile Ukrainian drones hit an explosives factory in Russia’s Samara region in an overnight strike, a member of Ukraine’s SBU security service told Reuters.

In his post, President Zelenskyy accused the United States of being “afraid” to name-check Russia in its comment on the attack.

“Unfortunately, the reaction of the American Embassy is unpleasantly surprising: such a strong country, such a strong people – and such a weak reaction,” he wrote on X.

“They are even afraid to say the word “Russian” when talking about the missile that killed children.”

America’s ambassador to Ukraine Bridget Brink had written on X: “Horrified that tonight a ballistic missile struck near a playground and restaurant in Kryvyi Rih.

“More than 50 people injured and 16 killed, including 6 children. This is why the war must end.”

Strike on Zelenskyy’s home city

President Zelenskyy went on in his post to say: “Yes, the war must end. But in order to end it, we must not be afraid to call a spade a spade.

“We must not be afraid to put pressure on the only one who continues this war and ignores all the world’s proposals to end it. We must put pressure on Russia, which chooses to kill children instead of a ceasefire.”

Grandmother ‘burned to death in her home’

Oleksandr Vilkul, head of the city’s defense council, said the missile attack, followed by a drone attack, had killed 19 people, including nine children.

“The Iskander-M missile strike with cluster munitions at the children’s playground in the residential area, to make the shrapnel fly further apart, killed 18 people.

“One grandmother was burnt to death in her house after Shahed’s direct hit.”

Russia’s defence ministry said it had struck a military gathering in a restaurant – an assertion rebutted by the Ukrainian military as misinformation.

“The missile hit right on the street – around ordinary houses, a playground, shops, a restaurant,” President Zelenskyy wrote.

Mr Zelenskyy also detailed the child victims of the attack including “Konstantin, who will be 16 forever” and “Arina, who will also be 7 forever”.

The UK’s chief of the defence staff Sir Tony Radakin said he had met the Ukrainian leader on Friday, along with French armed forces leader General Thierry Burkhard.

“Britain and France are coming together & Europe is stepping up in a way that is real & substantial, with 200 planners from 30 nations working to strengthen Ukraine’s long term security,” Sir Tony wrote.

The UK and France have spearheaded a so-called “coalition of the willing” – a group of countries that have pledged to help Ukraine secure if a ceasefire deal is reached with Russia.

Global markets have given Trump a clear no-confidence vote - and his fickleness is making the problem worse

Global financial markets gave a clear vote of no-confidence in President Trump’s economic policy.

The damage it will do is obvious: costs for companies will rise, hitting their earnings.

The consequences will ripple throughout the global economy, with economists now raising their expectations for a recession, not only in the US, but across the world.

Tariffs latest: FTSE 100 suffers biggest daily drop since COVID

Financial investors had been gradually re-calibrating their expectations of Donald Trump over the past few months.

Hopes that his actions may not match his rhetoric were dashed on Wednesday as he imposed sweeping tariffs on the US’ trading partners, ratcheting up protectionism to a level not seen in more than a century.

Markets were always going to respond to that but they are also battling with another problem: the lack of certainty when it comes to Trump.

More on Donald Trump

He is a capricious figure and we can only guess his next move. Will he row back? How far is he willing to negotiate and offer concessions?

These are massive unknowns, which are piled on to uncertainty about how countries will respond.

China has already retaliated and Europe has indicated it will go further.

That will compound the problems for the global economy and undoubtedly send shivers through the markets.

Much is yet to be determined, but if there’s one thing markets hate, it’s uncertainty.
