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.

Scientists have been forced to change their understanding of the inside of Mars after a major new breakthrough. Research looking at seismic waves that were generated when Mars was hit by a meteorite impact suggests that it has a previously unknown layer in its deep interior. Those waves were picked up by Nasa’s InSight lander, which was sent to Mars to better understand its seismic activity. The waves that the lander picked up can be used to get a picture of the anatomy of the planet, by watching how they travel around. The new data indicates the presence of a hitherto unknown layer of molten rock surrounding a liquid metallic core - the planet’s innermost component - that is smaller and denser than previously estimated, researchers said on Wednesday. Waves generated by quakes - including those caused by meteorite impacts - vary in speed and shape when journeying through different material inside a planet. Data from InSight’s seismometer instrument has enabled the planet’s internal structure to come into focus. The meteorite impact that occurred in a Martian highland region called Tempe Terra on Sept. 18, 2021, triggered a magnitude 4.2 quake and left a crater about 425 feet (130 meters) wide. It occurred on the opposite side of Mars from InSight’s location in a plains region called Elysium Planitia. “The importance of the far side impact was to produce seismic waves that traversed the deep interior of the planet, including the core. Previously, we had not observed any seismic waves that had transited the core. We had only seen reflections from the top of the core,” said planetary scientist Amir Khan of ETH Zurich in Switzerland, lead author of one of two scientific papers on the new findings published in the journal Nature. The behavior of the waves indicated that previous assessments of the Martian interior were missing something - the presence of a molten silicate layer about 90 miles (150 km) thick surrounding the core. This molten region sits at the bottom of the interior portion of the planet called the mantle. The researchers also recalculated the size of the core, finding that it has a diameter of about 2,080 miles (3,350 km), with a volume about 30% smaller than previously thought. The researchers said the mantle - a rocky layer sandwiched between the planet’s outermost crust and core - extends about 1,055 miles (1,700 km) below the surface. Unlike Mars, Earth has no molten layer around its core. One of the two studies published on Wednesday indicates this layer is fully molten, with the other indicating that most of it is fully molten, with the top portion partially molten. “The molten and partially molten layer is essentially composed of silicates (rock-forming minerals) that are enriched in iron and in radioactive heat-producing elements compared to the overlying solid mantle,” said Henri Samuel, a planetary scientist with the French national research organization CNRS working at Institut de Physique du Globe de Paris and lead author of the second study. The Martian core is made up mostly of iron and nickel, but also has some lighter elements such as sulfur, oxygen, carbon and hydrogen. The researchers concluded that these lighter elements make up about 9-15% of the core‘s composition by weight, lower than previously estimated. “This amount of light elements is not unlike that of the Earth’s core, which is estimated to be around 10%,” Khan said. Mars, the fourth planet from the sun, has a diameter of about 4,220 miles (6,791 km), compared to Earth’s diameter of about 7,926 miles (12,755 km). Earth is almost seven times larger in total volume. NASA retired InSight in 2022 after four years of operations. “We have learned a lot about Mars by studying the unique seismic record provided by the InSight mission,” Samuel said. “Planets are rich and complex systems because they are a place where many different types of processes coexist and act on various spatial and temporal scales, and Mars is no exception.” Additional reporting by Reuters Read More ‘Crystals brought back by Apollo astronauts indicate true age of the Moon’ Researchers reveal source of largest ever Mars quake Scientists investigate after huge shaking seen across Mars Scientists see huge explosion in space – and it could explain life Massive space explosion observed creating elements needed for life Tim Peake: Possibility of all-UK space mission a ‘very exciting development’
