Astronomers have found that renegade objects from alien star systems could be captured by Earth’s gravity and linger in orbit around our planet for potentially millions of years. However, most of these objects would likely be too small to detect with current telescopes, according to a new study published May 17 on the preprint server arXiv.

“Objects entering the solar system from the interstellar space outside of it can be trapped into bound orbits around the sun as a result of a close passage to Jupiter,” co-author Avi Loeb, a professor of physics at Harvard University, told Live Science in an email. “We investigate the possibility that some of them are captured and become Near-Earth Objects (NEOs).”

These “interstellar interlopers,” as the team calls them, would take the form of icy rocks jettisoned from their home star systems before taking up residence in ours. However, Loeb and his colleagues do not rule out the possibility that objects crafted by intelligent aliens could end up in our solar system as well.  Intruders in our solar system

Interstellar visitors have been of great interest to astronomers since 2017, when the first “intruder” space rock — a cigar-shaped object called ‘Oumuamua — was discovered in our cosmic backyard.

‘Oumuamua’s 1,300-foot-long (400 meters), highly elongated shape makes it around 10 times as long as it is wide, setting it apart from any known asteroids or comets native to our solar system. After observing the javelin-like space rock further, scientists concluded that it had been wandering our galaxy, unassociated with any star system, for hundreds of millions of years before its chance encounter with the solar system.

A renewed search for interstellar objects soon turned up a second object, the rogue comet Borisov — an Eiffel Tower-size ball of ice and dust from outside the solar system discovered in 2019.

Neither ‘Oumuamua nor Borisov is bound to the sun, meaning both objects will eventually exit the solar system as capriciously as they entered it, with the cigar-shaped object already fleeing beyond the orbit of Neptune. In their new paper, the study authors investigated whether other interstellar bodies could be caught by the gravity of the sun, or even the planets, and thus be forced to remain in the solar system.

Previous attempts to study this idea have focused on capture by the sun and Jupiter system. For the new study, the researchers set about investigating if Earth could also capture interstellar visitors and hold on to them as NEOs. 

Using numerical simulations, the team found that it is possible for Earth to periodically capture interstellar objects in its orbit. However, the effect is small compared with that of Jupiter, which is roughly a thousand times more efficient at catching interstellar objects than Earth is. 

Additionally, the researchers found that any objects caught by Earth’s gravity would be unstable and would survive around our planet for a shorter time than currently known NEOs do. Eventually, these objects would be disturbed by interactions with the other planets or the sun and would be hurled from the solar system just as they were once tossed from their planetary system of origin. related stories– 8 possible alien ‘technosignatures’ detected by AI in new study

Loeb explained that while the team doesn’t theorize that there are currently interstellar objects orbiting Earth, astronomers should continue to check for this possibility. And the forthcoming Vera C. Rubin Observatory, set to open its eye to the universe in August 2024, should help in this quest.

“Using computer simulations, we find that a few captured objects [roughly] the size of a football field would be detectable by the Rubin Observatory that will survey the Southern sky every four days with a 3.2 billion pixel camera,” Loeb said.

Studying interstellar objects around Earth could reveal new insights about the formation of distant star systems. However, Loeb added, there may be a small possibility that this interloper investigation could reveal something even more extraordinary. 

“Interstellar objects originate from outside the solar system and could potentially be technological in origin, similar to the five interstellar probes that humanity has launched, Voyager 1 and 2, Pioneer 10 and 11, and New Horizons,” Loeb said. (Of these five, only Voyager 1 and 2 have already left the solar system.) “If [the objects] are artificial in origin … they can tell us about extraterrestrial technological civilizations.”

‘They’re the ones who wronged us’: Freed Palestinian prisoner Zakaria Zubeidi rebukes UK and US over ‘harm they’ve caused’

'They're the ones who wronged us': Freed Palestinian prisoner Zakaria Zubeidi rebukes UK and US over 'harm they've caused'

One of the most high-profile prisoners to be released by Israel has told Sky News that the world has ignored Palestinians and says Britain is one of the countries he blames for taking away his freedom.

Zakaria Zubeidi was imprisoned in 2019 after being found guilty by an Israeli military court of involvement in terrorism.

He was released as part of the ceasefire agreement and welcomed back to the West Bank by crowds of well-wishers, including the man who was prime minister less than a year ago.

Analysis: Zubeidi an ‘extremist’ to Israel but inspiration to Palestine

In his first interview with a European broadcaster, Zubeidi told Sky News he still believes in “a resistance that will lead us to freedom” but claimed that Israeli occupation of the West Bank was wholly down to the international community.

“My life is worthless without freedom,” he said, speaking in Ramallah. “Freedom has no price. But the world that has denied me my freedom – particularly Britain, France, and the United States – must return what they have taken from me and my children.

“They are the ones who need to reconsider their mistakes, not me.

“They are the ones who have wronged us, and they should think about rectifying the harm they have caused to me and my children.”

Zubeidi, whose mother, brother and son have all died as a result of Israeli military action, has admitted involvement in a 2002 bombing that killed six people.

However, he has also been acclaimed by many in the West Bank as a symbol of the resistance.

He was famously part of a group of prisoners who briefly escaped their Israeli jail after using kitchen utensils to dig a tunnel.

“My message to the Palestinian people is to prioritise their safety and well-being because the assault being carried out against them is immense. I have no message for the occupation [Israel],” he said.

“My message is to the world – the same world that granted the occupation the right to live on my land – to grant me my freedom.”

In common with many other released prisoners, he claimed to have been beaten while behind bars, saying: “The situation in Israeli prisons is extremely harsh. We’ve witnessed it all: severe beatings, attack dogs, relentless insults. Every form of abuse imaginable has been inflicted on the bodies of our prisoners.”

While many in Israel will consider Zubeidi to be a dangerous, murderous extremist, he is considered a totemic figure in the West Bank, and a natural leader in Jenin, where he grew up in a refugee camp.

After being released, Israeli authorities banned him from returning to Jenin.

Instead, he has remained in Ramallah, where a long line of people came to a school building to shake his hand and hug him.

Among them, former prime minister Mohammad Shtayyeh, who resigned less than a year ago.

He embraced Zubeidi and told Sky News the release of prisoners could be a catalyst for an enduring peace deal.

“We would like to see all prisoners released and we would like to see all hostages going home,” said Mr Shtayyeh.

He continued: “It’s a historic moment for everybody. It’s time for this bloodshed to stop. And I think it is a moment of truth for everybody.

“In Gaza, 60,000 people have been killed, more than 120,000 have been injured. And of course, there have been so many casualties in Israel, too.

“We know that. And this time Palestinians are desperate for peace. We want a genuine peace process that does really bring peace and justice for everybody.”

More than 47,000 Palestinians have been killed in Israel’s offensive, according to Hamas-run authorities in Gaza, which does not distinguish between civilians and combatants.

The offensive followed Hamas’s attack on Israel on 7 October 2023, when it took 250 people hostage and killed around 1,200 others.

‘We’ll play some more soon’: Emails believed to be from Prince Andrew to Epstein after he claimed to cut contact revealed

'We'll play some more soon': Emails believed to be from Prince Andrew to Epstein after he claimed to cut contact revealed

The Duke of York told Jeffrey Epstein they would “play some more soon!” two months after he claimed he cut contact with the convicted paedophile.

The emails were disclosed in a filing by the Financial Conduct Authority (FCA), who are defending an appeal by former Barclays boss, Jes Staley.

Staley is challenging a decision to ban him from the industry for misleading regulators on his ties to Epstein, one of the most severe measures the FCA can impose.

The court documents show an exchange of messages between Epstein and “a member of the British Royal Family” – believed to be Prince Andrew. It suggests the duke and Epstein – who killed himself in jail in 2019 – were in contact for longer than he has previously admitted.

Barclays has frozen millions of pounds in bonus share awards made to their former boss mid an investigation into his relationship with disgraced financier and convicted sex offender Jeffrey Epstein. The banking giant's annual report revealed it has suspended all of Mr Staley's unvested long-term bonus share awards pending the regulatory probe. Issue date: Wednesday February 23, 2022.

In 2008, Epstein pleaded guilty to soliciting prostitution from a minor and was sentenced to 18 months in prison. After his release, Epstein and the duke were photographed walking together in New York’s Central Park, in December 2010.

The prince has claimed this was the last contact he had with Epstein.

In a 2019 interview with Newsnight, Andrew said he visited Epstein in person to tell him they could no longer be friends, believing it was the “honourable” thing to do.

More on Prince Andrew

Yet emails between the pair, which were handed to a court in London, show they kept exchanging messages until at least 27 February 2011.

On this date, Andrew emailed Epstein: “Keep in close touch and we’ll play some more soon!!!!”

The disgraced duke has come under fire for his relationship with the paedophile financier. In 2022, he settled a multi-million pound claim with Virginia Giuffre, who said she was trafficked by Epstein and forced to have sex with the royal.

Andrew stepped down from royal duties and public life and had claimed he never met Ms Giuffre. He agreed to settle the claim without admitting liability.

He has previously strenuously denied all allegations against him.

Newsnight interview ‘ill-advised’ – aide

Other court documents released on Friday revealed one of the prince’s senior aides admitted in a letter to an alleged Chinese spy that the duke’s Newsnight interview with Emily Maitlis was “hugely ill-advised and unsuccessful”.

Dominic Hampshire wrote to Yang Tengbo on Buckingham Palace notepaper in March 2020.

In the letter, he said they “have dealt with the aftermath of a hugely ill-advised and unsuccessful television interview”.

Mr Hampshire praised Mr Yang, writing that “in what originally seemed like a lost cause, you have somehow managed to not only salvage but maintain and then incredibly, enhance the reputation of my principal [Prince Andrew] in China.

“Under your guidance, we found a way to get the relevant people unnoticed in and out of the house in Windsor; we orchestrated a very powerful verbal message of support to China at a Chinese New Year’s dinner and between the three of us, we have written, amended and then always agreed a number of letters at the highest level possible.”

Mr Yang said in a statement on Friday the spying allegations against him are “entirely unfounded”.

The Jes Staley emails

Emails showed Epstein inviting Andrew to meet Staley on 27 February, saying: “jes staley will be in London on next tue afternoon, if you have time [sic].”

Andrew replied: “Jes is coming on 1st March or next week?”

The pair then engaged in a discussion about press articles, before the duke told Epstein they would “play some more soon”.

Sky News has contacted Prince Andrew for a comment.

The prince still making uncomfortable headlines for his family

Just when you thought Prince Andrew couldn’t fall any further, another twist emerges in his shameful association with Jeffrey Epstein.

He’d claimed the last time he had contact with the convicted paedophile was in December 2010, when the pair were infamously photographed together in Central Park.

The Duke of York insisted he thought he was being “honourable” when choosing to stay with Epstein and personally tell him they could no longer be friends.

But this email suggests the pair stayed in touch beyond this date. We don’t know for how long, but it leaves Prince Andrew once more facing difficult and damaging questions about his relationship with Jeffrey Epstein.

And yet again, Andrew’s judgement is under considerable scrutiny.

Last year had ended badly for the disgraced Duke after his association with an alleged Chinese spy was exposed. He had to keep clear of the Royal Family’s traditional Christmas day gathering at Sandringham.

The Duke of York has always denied witnessing or suspecting any of Epstein’s behaviour.

But their friendship cost him his reputation.

He now leads a reclusive life in Windsor, stripped of responsibility and royal roles. Yet still making uncomfortable headlines for the rest of his family.

This is New Jersey’s largest high-rise residential rooftop solar array

This is New Jersey's largest high-rise residential rooftop solar array

New York-based real estate developer LeFrak has installed the largest rooftop solar array on a high-rise multifamily residential building in New Jersey.

The Beach, a 336-unit waterfront rental tower in Jersey City’s Newport neighborhood, now hosts a 180kW, 450-panel rooftop solar system that will offset 13% of the building’s carbon emissions, equivalent to removing 37 gas-powered cars from the road annually. Sunkeeper Solar, a Brooklyn-based solar energy company, installed the nearly $1 million system.

The new rooftop solar offsets energy produced by electrical systems used in The Beach’s common area spaces, including those that power elevators and lighting, as well as cooling and ventilation in the high-rise building’s lobby and amenities. The Beach’s roof design and the building’s orientation optimize the amount of solar power generated by the system.

“Solar makes sense on multi-family buildings, and especially because Jersey City is vulnerable to the impacts of climate change, projects like this should become the bar for new development. Going solar saves consumers money, reduces air pollution, and creates a more resilient energy grid – solar is a double green amenity,” said Doug O’Malley, director of Environment New Jersey. 

Last year, LeFrak partnered with EV-sharing platform Envoy to offer Newport residents exclusive car-sharing benefits and access to a fleet of on-site electric vehicles, representing Envoy’s first expansion into New Jersey.
