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.
The COP29 climate talks have reached a last ditch deal on cash for developing countries, pulling the summit back from the brink of collapse after a group of countries stormed out of a negotiating room earlier.
The slew of deals finally signed off in the small hours of Sunday morning in Azerbaijan includes one that proved hardest of all – one about money.
Eventually the more than 190 countries in Baku agreed a target for richer polluting countries such as the UK, EU and Japan to drum up $300bn a year by 2035 to help poorer nations both curb and adapt to climate change.
It is a far cry from the $1.3trn experts say is needed, and from the $500bn that vulnerable countries like Uganda had said they would be willing to accept.
But in the end they were forced to, knowing they could not afford to live without it, nor wait until next year to try again, when a Donald Trump presidency would make things even harder.
Bolivia’s lead negotiator Diego Pacheco called it an “insult”, while the Marshall Islands’ Tina Stege said it was “not nearly enough, but it’s a start”.
UN climate chief Simon Stiell said: “This new finance goal is an insurance policy for humanity, amid worsening climate impacts hitting every country.
“No country got everything they wanted, and we leave Baku with a mountain of work still to do. So this is no time for victory laps.”
The funding deal was clinched more than 24 hours into overtime, and against what felt like all the odds.
The talks were rocked from the start by the incoming presidency of climate denier Mr Trump, the moment Argentina’s team were recalled back to Buenos Aires by their right-wing president and a controversial letter that sent shockwaves through the United Nations.

The fraught two weeks of negotiations pitted the anger of developing countries who are footing the bill for more dangerous weather that they did little to cause, against the tight public finances of rich countries.
A relieved Juan Carlos Monterrey Gomez, climate envoy for Panama, said there is “light at the end of the tunnel”.
Just hours ago, the talks almost fell apart as furious vulnerable nations stormed out of negotiations in frustration over that elusive funding goal.
They were also angry with oil and gas producing countries, who stood accused of trying to dilute aspects of the deal on cutting fossil fuels.

The UN talks work on consensus, meaning everyone has to agree for a deal to fly.
A row over how to follow up on last year’s pledge to “transition away from fossil fuels” was left unresolved and punted into next year, following objections from Chile and Switzerland for being too weak.
A draft deal simply “reaffirmed” the commitment but did not dial up the pressure in the way the UK, EU, island states and many others here wanted.
Saudi Arabia fought the hardest against any step forward on cutting fossil fuels, the primary cause of climate change that is intensifying floods, drought and fires around the world.
Governments did manage to strike a deal on carbon markets at COP29, which has been 10 years in the making and will allow countries to trade emissions cuts.

The UK’s energy secretary, Ed Miliband, said the deal is “not everything we or others wanted”, but described it as a “step forward”.
“It’s a deal that will drive forward the clean energy transition, which is essential for jobs and growth in Britain and for protecting us all against the worsening climate crisis,” he added.
“Today’s agreement sends the signal that the clean energy transition is unstoppable.
“It is the biggest economic opportunity of the 21st century and through our championing of it we can help crowd in private investment.”

“We have faced geopolitical headwinds and made every effort to be an honest broker for all sides.”
At least 20 people have been killed and 66 injured in Israeli strikes on central Beirut, Lebanese authorities have said.
Lebanon‘s health ministry said the death toll could rise as emergency workers dig through the rubble looking for survivors. DNA tests are being used to identify the victims, the ministry added.
The attack destroyed an eight-storey residential building and badly damaged several others around it in the Basta neighbourhood at 4am (2am UK time) on Saturday.

The Israeli military did not warn residents to evacuate before the attack and has not commented on the casualties.
At least four bombs were dropped in the attack – the fourth targeting the city centre this week.
A separate drone strike in the southern port city of Tyre this morning killed two people and injured three, according to the state-run National News Agency.
The victims were Palestinian refugees from the nearby al Rashidieh camp who were out fishing, according to Mohammed Bikai, spokesperson for the Fatah Palestinian faction in the Tyre area.
Israel’s military warned residents today in parts of Beirut’s southern suburbs that they were near Hezbollah facilities, which the army would target in the near future. The warning, posted on X, told people to evacuate at least 500 metres away.
The army said that over the past day it had conducted intelligence-based strikes on Hezbollah targets in Dahiyeh, in Beirut’s southern suburbs, where Hezbollah has a strong presence. It said it hit several command centres and weapons storage facilities.

Israel has killed several Hezbollah leaders in air strikes on the capital’s southern suburbs.
Heavy fighting between Israel and Hezbollah is ongoing in southern Lebanon, as Israeli forces push deeper into the country since launching a major offensive in September.
According to the Lebanese health ministry, at least 3,670 people have been killed in Israeli attacks there, with more than 15,400 wounded.
It has displaced about 1.2 million people – a quarter of Lebanon’s population – while Israel says about 90 soldiers and nearly 50 civilians have been killed in northern Israel.

Meanwhile, six people, including three children and two women, were killed in the southern Gazan city of Khan Younis.
Some 44,176 Palestinians have been killed since the start of Israel’s military campaign in Gaza, according to the Gaza health ministry.
The ministry does not distinguish between civilians and combatants in its count, but it has said that more than half of the fatalities are women and children.
The war began when Hamas-led militants stormed into southern Israel on 7 October 2023, killing some 1,200 people and taking another 250 hostage.
US envoy Amos Hochstein was in the region this week to try to end more than 13 months of fighting between Israel and Hezbollah, ignited last October by the war in Gaza.
Mr Hochstein indicated progress had been made after meetings in Beirut on Tuesday and Wednesday, before going to meet Israeli Prime Minister Benjamin Netanyahu and defence minister Israel Katz.
