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.

One mom is exposing her secrets for first-time parents. In an interview with Today, mother of three Caroline Chambers opened up about the difficulties she endured with her first-born child. Although it’s very normal for mothers to experience certain symptoms related to postpartum, Chambers’ year of anxiety after delivery felt particularly difficult. “The first year of my child’s life was plagued with so much anxiety and fear,” she said. “Of course, I was obsessed with him and had so many amazing moments of just loving it, but there was also just a lot of fear around the unknown.” Despite the cookbook author’s prior struggles, she was still keen to grow her family. By the time her second child, Callum, was born, she’d gained a new perspective on being a parent. “None of it matters. They’re going to sleep eventually. None of it is actually a pattern. You can’t actually diagnose it. You can’t actually Google your way into better sleep. It just takes time,” she recalled to the outlet. Chambers is a mother to three sons: Mattis, five, Callum, three, and Cashel, one. While feeding schedules and nap times for her son Mattis were overwhelming and stress-inducing, Callum’s care was a “more joyful” experience for her, having already known what works and what doesn’t for newborns. The intuitive mother recognised that both parenthood and being a mother is “terrifying the first time because you don’t know what to expect”. Still, she explained that welcoming more children into her life helped her learn that babies aren’t the “precious little fragile creatures that we think they are.” Chambers took to her Instagram account last April, revealing her tips for raising your first child like your third. First, she suggested taking opportunities to “leave your baby”. Chambers emphasised the importance of taking time for yourself and allowing babysitters to take over for a few hours, so you can either go on a solo date or enjoy time with your partner. “Your husband isn’t the enemy. The baby is the enemy,” Chambers jokingly wrote. For her next tip, she said that “this too shall pass.” According to Chambers, each phase for a baby is fleeting, lasting around “two weeks and it’s on to the next thing”. Chambers also told her followers not to leave the house chores for when your baby asleep. Not only will this feel like you’re being overworked without any breaks, but Chambers pointed out how babies don’t mind watching you vacuum or do the dishes. “Put on your oxygen mask first,” she continued. “You can’t take care of your baby if you can’t take care of yourself. Take a shower. Eat delicious meals with lots of greens and protein. If you feel sad, call your OB and tell her about those feelings... Get a blowout. Go get lunch or dinner by yourself.” Lastly, Chambers urged mothers not to fall victim to the “four Bs of a bedtime routine” and maintained that following the sequence of “bath, boob/bottle, book, bed” isn’t necessary. “As long as the baby is fed and in bed, they will not care how you get them there. Dunked in the bath once a week, they are FINE,” she wrote. Many thankful mothers chimed in, adding their own advice and experience after Chambers encouraged them to do so in her caption. “Love this!!!!! We bathe our baby one to two times a week. MAX. I’d also add: the whole eat, play sleep order is BS! Don’t stress about it. Feed when they need it. Love following you & learning mama,” one mother noted. Another commented: “For the toddler phase: Tell them, ‘I’m going to close my eyes and when I open them, I’ll see… (insert whatever you’re trying to get them to do)”. This ALWAYS works for my kiddo when I need him to put on his clothes, go to the bathroom, etc. It’s magic!” The Independent has reached out to Chambers for a comment.
