Astrophysicists call for international cooperation on ambitious probe, amid growing interest in the mysterious planet

European space scientists have been urged to join forces with Nasa to ensure the success of one of the most ambitious space missions planned for launch this century.

Joining a robot spaceflight to the mysterious planet Uranus would offer “the opportunity to participate in a groundbreaking, flagship-class mission”, astrophysicists have said.

Labour leader says it was ‘most efficient form of transport’ from Wales and party has offset the carbon

Keir Starmer has admitted he used a private jet to travel to a campaign rally in Scotland where he promised to create “tens of thousands” of clean energy jobs with a new publicly owned energy company in the country.

Responding to media questions after speaking to activists in Greenock, Inverclyde, Starmer said: “We did use a private jet because we did need to get very quickly to Scotland from Wales yesterday and it was the most efficient form of transport in the middle of a very busy general election campaign.”

Mercury, Mars, Jupiter, Saturn, Neptune and Uranus will be visible but viewers may need some equipment to see them clearly

Stargazers are in with a chance of a celestial treat on Monday with six planets appearing in alignment.

Mercury, Mars, Jupiter, Saturn, Neptune and Uranus will take part in the parade – which occurs when planets gather on the same side of the sun.

It's been 300 years since Galileo and Isaac Newton started fiddling around with lenses and parabolic mirrors to get a better look at the heavens. But if you look at many of the best amateur telescopes today, you'd be forgiven for thinking they haven't progressed much since.

Though components have certainly improved, the basic combination of mirrors and lenses is more or less the same. Even the most advanced "smart" mounts that hold them rely on technology that hasn't progressed in 30 years.

Compared to the radical reinvention that even the humble telephone has received, it's sad that telescope tech has largely been left behind. But that is finally changing. Companies like Unistellar and Vaonis are pioneering a new generation of scopes that throw classic astronomy norms and concepts out the window in favor of a seamless setup and remarkable image quality.

British soldiers stationed in Kenya have been accused of rights violations and offences including murder

Kenya has launched public hearings into allegations of human rights violations and abuses of power by British troops based in the former colony.

The British Army Training Unit Kenya (Batuk) is an economic lifeline for many in the central town of Nanyuki, where it maintains a permanent base, but soldiers stationed there have also been accused of committing offences including murder.

UK founder, accused of inflating sales and misleading regulators, takes stand and says he wasn’t fully responsible for firm’s decisions

The British entrepreneur Mike Lynch took the stand on Thursday in a San Francisco federal courthouse as a key witness in his own criminal fraud trial, defending his role at Autonomy, the tech firm he co-founded and then sold.

The trial continued as planned Thursday despite the defense team moving for a mistrial over alleged improper questioning of a witness by the prosecution. Lynch’s defense team called the questioning, which indirectly referenced the tech titan’s extradition, “egregious” and ‘’highly improper” in a filing.

Wandering worlds are seen deep inside Orion nebula, a giant cloud of dust and gas 1,500 light years away

Astronomers have spotted dozens of rogue planets floating free from their stars after turning the Euclid space telescope to look at a distant region of the Milky Way.

The wandering worlds were seen deep inside the Orion nebula, a giant cloud of dust and gas 1,500 light years away, and described in the first scientific results announced by Euclid mission researchers.

Joe Biden and Donald Trump agree on tariffs against China. The world has lost its biggest cheerleader for globalisation

The biggest shift in American politics has nothing to do with Stormy Daniels or Michael Cohen, Fox News or golf courses. Indeed, its author is not Donald J Trump. Yet the implications stretch far beyond this year’s presidential elections, and affect countries across the world. The era of free trade is dying, and the man bringing down the guillotine represents the party that in the past three decades has been evangelically pro-globalisation: the Democrats.

Last week, Joe Biden imposed tariffs on a range of Chinese-made goods. Electric cars produced in China will now be hit with import tax of 100%, chips and solar cells 50% and lithium-ion batteries 25%. These and other tariffs on goods worth an estimated $18bn a year amount to a rounding error in the giant US economy. And in an election year, Mr Biden, who hails from Scranton, Pennsylvania, is fretting about support not only in his home state but across the country’s industrial heartland, gutted by decades of free trade.

Trump’s Truth Social account reposted a video about a second term showing a fake newspaper that referred to a ‘unified reich’

• Sign up for the Stakes: a free newsletter on the 2024 US presidential election

Welcome back to the Stakes, our weekly US politics newsletter. I cover democracy issues, and I’m filling in for Adam Gabbatt this week as Donald Trump flirted with a third term in office (yes, that’s illegal) and posted a video promising a “unified reich” (yes, that’s Nazi-adjacent language). Weird how these anti-democratic “gaffes” keep happening! We’ll get into why that might be, after a look at what else is happening in US politics.

Trump rests, but doesn’t get any rest

On the 20th day of the hush-money trial in New York, Trump declined to take the stand and the defense rested. Trump had falsely claimed he wasn’t allowed to take the stand: he was, and he chose not to. Outside the courtroom, he said although the defense would rest quickly, he himself would not be resting. “I don’t rest. I’d like to rest sometimes, but I don’t get to rest.”

Biden’s Israel problem

The international criminal court’s prosecutor applied for arrest warrants for leaders of Israel and Hamas, and Joe Biden is not pleased. He called the warrant application “outrageous” and said: “We will always stand with Israel against threats to its security.” His strong backing of Israel comes as the progressive left continues to pressure him to end US support for the Israel-Gaza war.

That’s not the way the flag goes

An upside-down US flag – a symbol of those who believed the 2020 election was stolen – flew outside the home of the supreme court justice Samuel Alito’s home shortly after the January 6 insurrection in 2021. Alito blamed his wife, saying she did it as part of a dispute with a neighbor, but many observers saw it as the latest example of the politicization of the high court.

The new Harris poll, conducted for the Guardian is troubling, not only because it shows Americans are still pessimistic about the economy but also because – with election day just five and a half months away – so many Americans believe the economy is bad when in fact it’s damn good.

In the Harris poll, 55% think the economy is shrinking and 56% believe the US is in a recession. In fact, the economy is growing.

Exclusive Harris poll for the Guardian shows 55% believe economy is shrinking, in troubling sign for president’s re-election bid

• Do you know how US economy is actually doing? Try our interactive quiz

Nearly three in five Americans wrongly believe the US is in an economic recession, and the majority blame the Biden administration, according to a Harris poll conducted exclusively for the Guardian. The survey found persistent pessimism about the economy as election day draws closer.

The poll highlighted many misconceptions people have about the economy, including:

55% believe the economy is shrinking, and 56% think the US is experiencing a recession, though the broadest measure of the economy, gross domestic product (GDP), has been growing.

49% believe the S&P 500 stock market index is down for the year, though the index went up about 24% in 2023 and is up more than 12% this year.

49% believe that unemployment is at a 50-year high, though the unemployment rate has been under 4%, a near 50-year low.

• Exclusive: majority of Americans wrongly believe US is in recession – and most blame Biden

The United States is less than six months away from sending either Joe Biden or Donald Trump back to the White House.

For many voters mulling this decision, the economy is front of mind. But how it’s doing, and how it’s feeling, are not one and the same.

When you look at the northern sky, you can follow the arm of the Big Dipper as it arcs around toward the bright star called Arcturus. Roughly in the middle of that arc, you'll find the Northern Crown constellation, which looks a bit like a smiley face. Sometime between now and September, if you look to the left-hand side of the Northern Crown, what will look like a new star will shine for five days or so.

This star system is called T. Coronae Borealis, also known as the Blaze Star, and most of the time, it is way too dim to be visible to the naked eye. But once roughly every 80 years, a violent thermonuclear explosion makes it over 10,000 times brighter. The last time it happened was in 1946, so now it’s our turn to see it.

Neighborhood litterbug

“The T. Coronae Borealis is a binary system. It is actually two stars,” said Gerard Van Belle, the director of science at Lowell Observatory in Flagstaff, Arizona. One of these stars is a white dwarf, an old star that has already been through its fusion-powered lifecycle. “It’s gone from being a main sequence star to being a giant star. And in the case of giant stars, what happens is their outer parts eventually get kind of pushed into outer space. What’s left behind is a leftover core of the star—that’s called a white dwarf,” Van Belle explained.

Comments come as Commission president hints EU could impose tariffs on Chinese electric vehicles

• Business live – latest updates

Janet Yellen, the US treasury secretary, has urged the EU to intervene urgently to dampen the growing export levels of Chinese cut-price green technology including solar panels and wind turbines, pushing European leaders to move to a full-scale trade war.

At the same time she urged German bank executives on Tuesday to step up efforts to comply with sanctions against Russia and shut down efforts to circumvent them to avoid potential penalties themselves that could see the US cut them off from dollar access.

The travel photography site Capture the Atlas has published the seventh edition of its Milky Way photographer of the year collection. The Milky Way season ranges from February to October in the northern hemisphere and from January to November in the southern hemisphere. The best time to see and photograph the Milky Way is usually between May and June, when hours of visibility are at their maximum on both hemispheres – away from light-polluted areas such as cities, and preferably at higher elevation

Employers in UK, one of 15 countries studied, willing to pay 14% wage premium for jobs requiring AI skills

The sectors of the global economy most heavily exposed to artificial intelligence (AI) are witnessing a marked productivity increase and command a significant wage premium, according to a report.

Boosting hopes that AI might help lift the global economy out of a 15-year, low-growth trough, a PwC study found productivity growth was almost five times as rapid in parts of the economy where AI penetration was highest than in less exposed sectors.

PM gives statement following report that found ‘subtle, pervasive and chilling’ cover-up by NHS and government

GB News has described the Ofcom ruling against it today (see 10.51am and 11.01am) as an “alarming development” that should “terrify” anyone who believes in a free media. Here is its response to the judgment in full.

Ofcom’s finding against GB News today is an alarming development in its attempt to silence us by standing in the way of a forum that allows the public to question politicians directly.

The regulator’s threat to punish a news organisation with sanctions for enabling people to challenge their own prime minister strikes at the heart of democracy at a time when it could not be more vital.

In considering whether the programme was duly impartial, we took into account a range of factors, such as: the audience’s questions to the prime minister; the prime minister’s responses; the presenter’s contribution; and whether due impartiality was preserved through clearly linked and timely programmes. Our investigation found, in summary, that:

-while some of the audience’s questions provided some challenge to, and criticism of, the government’s policies and performance, audience members were not able to challenge the prime minister’s responses and the presenter did not do this to any meaningful extent;

Given the very high compliance risks this programme presented, we found GB News’s approach to compliance to be wholly insufficient, and consider it could have, and should have, taken additional steps to mitigate these risks.

We found that an appropriately wide range of significant viewpoints were not presented and given due weight in the People’s Forum: The Prime Minister, nor was due impartiality preserved through clearly linked and timely programmes. As a result, we consider that the prime minister had a mostly uncontested platform to promote the policies and performance of his government in a period preceding a UK general election.

An asteroid that has been wandering through space for billions of years is going to have been bombarded by everything from rocks to radiation. Billions of years of traveling through interplanetary space increases the odds of colliding with something in the vast emptiness, and at least one of those impacts had enough force to leave the asteroid Ryugu forever changed.

When the Japanese Space Agency’s Hayabusa2 spacecraft touched down on Ryugu, it collected samples from the surface that revealed that particles of magnetite (which is usually magnetic) in the asteroid’s regolith are devoid of magnetism. A team of researchers from Hokkaido University and several other institutions in Japan are now offering an explanation for how this material lost most of its magnetic properties. Their analysis showed that it was caused by at least one high-velocity micrometeoroid collision that broke the magnetite’s chemical structure down so that it was no longer magnetic.

“We surmised that pseudo-magnetite was created [as] the result of space weathering by micrometeoroid impact,” the researchers, led by Hokkaido University professor Yuki Kimura, said in a study recently published in Nature Communications.

Protectionism in the form of tariffs is justified but the focus will be on whether Beijing retaliates

The global economy is fragmenting and a new era of protectionism has dawned. Dreams by free marketeers of a frictionless world in which goods and services moved seamlessly from country to country are dead.

That was the clear message from Joe Biden’s decision last week to target China with a range of new, much higher tariffs on electric vehicles and a range of other products crucial to sectors seen by the White House as vital to the future health of the US economy and to national security.

As a slew of Republicans went to the hush-money trial to show their fealty to their boss, the president tried to rise above it

Donald Trump last week turned his New York fraud trial into a political circus and a platform for his election campaign while Joe Biden struggled to persuade voters that they’re wrong about the economy.

Trump engineered a parade of leading Republicans to demonstrate their allegiance outside the courthouse in downtown Manhattan even as his trial laid bare the swamp that is the former US president’s professional and personal life.

Fossil-fuel dependent country hopes to provide bridge between wealthy global north and poor south at November gathering

Oil is inescapable in Baku, the capital of Azerbaijan. The smell of it greets the visitor on arrival and from the shores of the Caspian Sea on which the city is built the tankers are eternally visible. Flares from refineries near the centre light up the night sky, and you do not have to travel far to see fields of “nodding donkeys”, small piston pump oil wells about 6 metres (20ft) tall, that look almost festive in their bright red and green livery.

It will be an interesting setting for the gathering of the 29th UN climate conference of the parties, which will take place at the Olympic Stadium in November.

Galaxies pass gas—in the case of galaxy NGC 4383, so much so that its gas outflow is 20,000 light-years across and more massive than 50 million Suns.

Yet even an outflow of this immensity was difficult to detect until now. Observing what these outflows are made of and how they are structured demands high-resolution instruments that can only see gas from galaxies that are relatively close, so information on them has been limited. Which is unfortunate, since gaseous outflows ejected from galaxies can tell us more about their star formation cycles.

The MAUVE (MUSE and ALMA Unveiling the Virgo Environment) program is now changing things. MAUVE’s mission is to understand how the outflows of galaxies in the Virgo cluster affect star formation. NGC 4383 stood out to astronomer Adam Watts, of the University of Australia and the International Centre for Radio Astronomy Research (ICRAR), and his team because its outflow is so enormous.
