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.

Trump vowed to end Ukraine war in first 24 hours of his presidency – nearly 200 days in, could he be close?
Seven hours is a long time in US politics.
At 10am, Donald Trump accused Russia of posing a threat to America’s national security.
By 5pm, Mr Trump said there was a “good prospect” of him meeting Vladimir Putin “soon”.
There had, he claimed, been “great progress” in talks between his special envoy Steve Witkoff and the Russian president.
It’s difficult to gauge the chances of a meeting between the two leaders without knowing what “great progress” means.
Is Russia “inclined” towards agreeing a ceasefire, as Ukraine’s president now claims?
Is Mr Putin prepared to meet with his Ukrainian foe, Volodymyr Zelenskyy, too?
The very fact that we’re asking those questions suggests something shifted on a day when there was no expectation of a breakthrough.

Zoo kills 12 healthy baboons to ease overcrowding
Listen to The World with Richard Engel and Yalda Hakim every Wednesday
Mr Trump repeatedly vowed to end the war within 24 hours of becoming president.
On day 198 of his presidency, he might, just might, be one step closer to achieving that.
Staff at a zoo in Germany which culled 12 baboons and fed some of their carcasses to the lions say they have received death threats.
Tiergarten Nuremberg euthanised the healthy Guinea baboons at the end of July due to overcrowding in their enclosure.
Some remains were used for research while the rest were fed to the zoo’s carnivores.
Plans to kill the baboons were first announced last year after the population exceeded 40, and protestors gathered outside the zoo to show their outrage.
When the site closed last Tuesday to carry out the cull, several activists were arrested after climbing the fence.
The director of the zoo defended the decision, saying efforts to sterilise and rehome some baboons had failed.
“We love these animals. We want to save a species. But for the sake of the species, we have to kill individuals otherwise we are not able to keep up a population in a restricted area,” Dr Dag Encke told Sky News.

‘The staff are suffering’
He said police are investigating after he and the staff were sent death threats.
“The staff are really suffering, sorting out all these bad words, insults and threats,” Dr Encke said.
“The normal threat is ‘we will kill you, and we’ll feed you to the lions’.
“But what is really disgusting is when they say that’s worse than Dr Mengele from the National Socialists, who was one of the most cruel people in human history.
“That is really insulting all the victims of the Second World War and the Nazi regime.”
Josef Mengele was a Nazi officer who performed deadly experiments on prisoners at the Auschwitz concentration camp during the Second World War.

Zoo animals ‘treated as commodities’
Culling animals and feeding them to predators isn’t unheard of in zoos.
In 2014, Copenhagen Zoo caused controversy by euthanizing an 18-month-old male giraffe called Marius and feeding his body to the lions.
At the time, the zoo said it was due to a duty to avoid inbreeding.
Dr Mark Jones, a vet and head of policy at Born Free Foundation, a charity which campaigns for animals to be kept in the wild, denounced the practice and said thousands of healthy animals are being destroyed by zoos each year.
“It reflects the fact animals in zoos are often treated as commodities that are disposable or replaceable,” he said.

Zoo asks for unwanted pets
Earlier this week, a zoo in Denmark faced a backlash for asking for unwanted pets to be donated to be used as food for its predators.
In a Facebook post, Aalborg Zoo said it could take smaller live animals such as chickens, rabbits and guinea pigs, as well as horses under 147cm. It said the animals would be euthanised by specially trained staff before being fed to carnivores like the European lynx.
While some people supported the scheme, saying they had donated animals in the past, others are outraged.
“The very idea of a zoo offering to take unwanted pets in order to kill them and feed them to their predators will, I think, horrify most right-minded people,” said Dr Jones.

Aalborg Zoo has now closed the post to comments and said in a statement: “For many years at Aalborg Zoo, we have fed our carnivores with smaller livestock.
“When keeping carnivores, it is necessary to provide them with meat, preferably with fur, bones, etc., to give them as natural a diet as possible.
“Therefore, it makes sense to allow animals that need to be euthanised for various reasons to be of use in this way.
“In Denmark, this practice is common, and many of our guests and partners appreciate the opportunity to contribute.”

Trump could meet Putin as early as next week to discuss Ukraine ceasefire – White House official
Donald Trump could meet Vladimir Putin in person as early as next week to discuss a ceasefire in Ukraine, a White House official has said.
They said the meeting would be conditional on the Russian president meeting his Ukrainian counterpart Volodymyr Zelenskyy, Sky News’s US partner network NBC News reported.
It came days before the White House’s deadline for Russia to reach a peace deal with Ukraine or face severe economic penalties, which could also target countries buying its oil.
Asked during a news conference at the White House if the talks would take place, Mr Trump said: “There’s a very good prospect that they will.”
He said it had not been determined where the talks would take place, but added: “We had some very good talks with President Putin today.”
However, he said: “I’ve been disappointed before with this one.”
Asked if Mr Putin made any kind of concession to lead to the development, Mr Trump did not give much away, but added: “We’ve been working on this a long time. There are thousands of young people dying, mostly soldiers, but also, you know, missiles being hit into Kyiv and other places.”
More tariffs ‘could happen’
Mr Trump also said he could announce further tariffs on China similar to the 25% he announced on India over its purchases of Russian oil.
“Could happen,” he said, after saying he expected to announce more secondary sanctions intended to pressure Russia into ending its war with Ukraine.
Earlier, he imposed an additional 25% tariff on Indian goods, on top of a previous 25% tariff, over its continued purchases of Russian oil.
India’s foreign ministry spokesperson said the additional tariffs were “unfair, unjustified and unreasonable”.

It came after Mr Putin held talks with Mr Trump‘s special envoy Steve Witkoff in Moscow, with the meeting lasting around three hours.
In a post on Truth Social, Mr Trump said Mr Witkoff “had a highly productive meeting” with Mr Putin in which “great progress was made”.
He said he had updated America’s European allies, and they will work towards an end to the Russia-Ukraine war “in the days and weeks to come”.

‘The war must end’
Mr Zelenskyy later said he and Mr Trump spoke on the phone after the meeting. He said “European leaders also participated in the conversation” and “we discussed what was said in Moscow”.
He added: “Our common position with our partners is absolutely clear: The war must end. We all need lasting and reliable peace. Russia must end the war that it started.”
Mr Zelenskyy later said: “It seems that Russia is now more inclined to agree to a ceasefire.”
He added that the pressure on Moscow “is working”, without elaborating, and stressed it was important to make sure Russia does not “deceive us or the United States” when it comes to “the details” of a potential agreement.
