Scientists have spotted an infrared aurora on Uranus that could help us find alien life. On Earth, aurorae are best known in the form of the northern lights, when bright light streaks across the sky. Uranus also has its own aurora – though it is not visible in the same way, because of the different atmosphere on that planet. Researchers have known about ultraviolet aurorae on Uranus since 1986. But now scientists have confirmed there are infrared aurorae on the distant planet, too. Scientists hope that the findings could help explain the magnetic fields of other planets in our solar system. And it could help us find out whether distant planets support alien life. Aurorae happen when charged particles arrive at a planet and hit its atmosphere, brought down through its magnetic field lines. To better understand those on Uranus, researchers analysed the light from the planet and watched for a specific charged particle that changes brightness depending on how how it is and how dense the atmosphere is, so that it can be used as a thermometer. The researchers found that the density of that particle significantly increased, which suggests they are being ionised by an infrared aurorae, they say. Scientists hope that will inform our understanding of other, similar planets, as well as which worlds might be suitable for alien life. “The temperature of all the gas giant planets, including Uranus, are hundreds of degrees Kelvin/Celsius above what models predict if only warmed by the sun, leaving us with the big question of how these planets are so much hotter than expected? One theory suggests the energetic aurora is the cause of this, which generates and pushes heat from the aurora down towards the magnetic equator,” said Emma Thomas from the University of Leicester, who was lead author on the new study. “A majority of exoplanets discovered so far fall in the sub-Neptune category, and hence are physically similar to Neptune and Uranus in size. This may also mean similar magnetic and atmospheric characteristics too. By analysing Uranus’s aurora which directly connects to both the planet’s magnetic field and atmosphere, we can make predictions about the atmospheres and magnetic fields of these worlds and hence their suitability for life. “This paper is the culmination of 30 years of auroral study at Uranus, which has finally revealed the infrared aurora and begun a new age of aurora investigations at the planet. Our results will go on to broaden our knowledge of ice giant auroras and strengthen our understanding of planetary magnetic fields in our solar system, at exoplanets and even our own planet.” The findings might also help explain a mysterious phenomenon on Earth known as geomagnetic reversal, where the north and south pole switch around. Scientists still know very little about that rare phenomenon, and how it might affect things such as satellites and communications. That process happens every day on Uranus, however. Researchers hope they can use its aurorae to get better data on the nature of that reversal – and what might happen if Earth has one, too. The findings are described in a new paper, ‘Detection of the infrared aurora at Uranus with Keck-NIRSPEC’, published in Nature Astronomy.

Nottingham Forest will have designs on picking up all three points against struggling Brighton when the teams clash at the City Ground this afternoon. Steve Cooper wants his Forest side to close out matches with clinical performances when they’ve been on top as he looks to continue to distance his team from the bottom three. Forest slipped to defeat last time out against West Ham, thanks to a late goal from Tomas Soucek, and will want to rectify that today. After a wonderful start for Brighton where they won five of their first six games, Roberto de Zerbi’s men have not triumphed in the league since September. Four draws from their last five games is a frustrating return for the Seagulls who have their sights set on Europe. Follow the latest action from the Premier League below.

Manchester City start their Champions League title defence at home to Red Star Belgrade. Pep Guardiola’s side could not have got their domestic season off to a better start, they have won all of their first five matches and are already top of the league with a two-point gap to Tottenham, Liverpool and Arsenal. Last season, the trophy they most coveted - the Champions League - which had evaded them was finally in their grasp as they held it aloft for the first time following a 1-0 win over Inter Milan. They became only the second English club to win the treble last season, and it remains to be seen if anyone can stop them repeating the feat this campaign, and they could even surpass it with the addition of the Fifa Club World Cup. Here’s everything you need to know ahead of tonight’s Champions League clash. Plus you can get all the latest football betting sites offers here. When is Man City v Red Star Belgrade? The match kicks off at 8pm BST on Tuesday 19 September at the Etihad Stadium in Manchester. Where can I watch it? Man City v Red Star Belgrade will be broadcast live on TNT Sports 2 and TNT Sports Ultimate. it will be streamed live on the Discovery+ app and desktop website for subscribers. What is the team news? Guardiola said after his side’s win at West Ham at the weekend that he would be forced to make changes to his line-up in the upcoming weeks to protect players, something which could come as soon as Tuesday. City are due to play four matches in just 11 days, a tough ask for any team, especially considering that comes off the back of an international break that saw many members of the team travel as far as South America. They will continue to be without the injured Kevin De Bruyne, while the match could also come too soon for John Stones, Jack Grealish and Mateo Kovacic. Predicted lineup Man City XI: Ederson, Walker, Akanji, Ake, Rodri, Bernardo Silva, Foden, Alvarez, Doku, Haaland Odds Man City 1/25 Draw 12/1 Red Star Belgrade 35/1 Prediction Red Star can be difficult opponents in the Champions League, but usually only at their home ground and they are likely to struggle to impose themselves against City. They will try to utilise a vocal travelling support, but will be unable to stop the home side.

Linda Evangelista has described her relationship with ex-husband Gerald Marie as a “MeToo marriage”, in the first episode of Kirsty Young’s new podcast. On Young Again, the BBC broadcaster interviews a number of famous figures about what they would tell their younger selves if given the opportunity. Evangelista reflected on her 40-year career as one of the first international supermodels, her upbringing, and her regret at not speaking about her abusive marriage sooner. The 58-year-old was married to Marie, the former head of the European division of Elite Models, from 1987 until 1993. “Did I have #MeToo moments? Absolutely. I was in a #MeToo marriage. Absolutely,” she told Young. “I kept quiet for many many years. And The Guardian did a story on all the models. Only when speaking to the journalist did I find this out. And to think that I was married to him when all this was happening, is crazy. “And there’s a side of me that thinks that if I would have spoken up and said something about what was happening to me, that maybe they would have come forward at that time. And the statute of limitations wouldn’t have run out.” In 2020, seven women accused Marie of rape and sexual misconduct, which he denied. The investigation was closed without charges last month. In a recent Apple TV+ documentary, The Super Models, Evangelista described the marriage as “an abusive relationship” and claimed Marie knew not to touch her face because that was “the money-maker”. In a statement, the 73-year-old denied the abuse allegations, and said he “has never committed the slightest act of violence”. The Super Models profiled modelling stars Naomi Campbell, Evangelista, Christy Turlington and Cindy Crawford, exploring their careers as the most sought-after models in the fashion industry during the late Eighties and Nineties. Campbell, Evangelista, Turlington and Crawford, now in their fifties and with children of their own, offer a snapshot into their early careers. Each episode – “The Look,” “The Fame,” “The Power” and “The Legacy” – features archival footage from their heyday and intimate interviews with each model. The first three episodes of Young Again, the new podcast from Young, are available now on BBC Sounds. Future episodes will be broadcast weekly on BBC Radio 4 at 11am from 3 October.
