The planet Uranus and its five biggest moons may not be the dead sterile worlds that scientists have long thought. Instead, they may have oceans, and the moons may even be capable of supporting life, scientists say. Much of what we know about them was gathered by Nasa’s Voyager 2 spacecraft which visited nearly 40 years ago. But a new analysis shows that Voyager's visit coincided with a powerful solar storm, which led to a misleading idea of what the Uranian system is really like. Uranus is a beautiful, icy ringed world in the outer reaches of our solar system. It is among the coldest of all the planets. It is also tilted on its side compared to all the other worlds – as if it had been knocked over – making it arguably the weirdest. We got our first close-up look at it in 1986, when Voyager 2 flew past and sent back sensational pictures of the planet and its five major moons. But what amazed scientists even more was the data Voyager 2 sent back indicating that the Uranian system was even weirder than they thought. The measurements from the spacecraft’s instruments indicated that the planets and moons were inactive, unlike the other moons in the outer solar system. They also showed that Uranus’s protective magnetic field was strangely distorted. It was squashed and pushed away from the Sun. A planet’s magnetic field traps any gases and other material coming off the planet and its moons. These might be from oceans or geological activity. Voyager 2 found none, suggesting that Uranus and its five largest moons were sterile and inactive. This came as an enormous surprise because it was unlike the solar system’s other planets and their moons. But the new analysis has solved the decades-long mystery. It shows that Voyager 2 flew past on a bad day. The new research shows that just as Voyager 2 flew past Uranus, the Sun was raging, creating a powerful solar wind that might have blown the material away and temporarily distorted the magnetic field. So, for 40 years we have had an incorrect view of what Uranus and its five largest moons are normally like, according to Dr William Dunn of University College London. “These results suggest that the Uranian system could be much more exciting than previously thought. There could be moons there that could have the conditions that are necessary for life, they might have oceans below the surface that could be teeming with fish!”. Linda Spilker was a young scientist working on the Voyager programme when the Uranus data came in. She is now still serving as the project scientist for the Voyager missions. She said that she was delighted to hear about the new results, which have beenpublished in the Journal Nature Astronomy. “The results are fascinating, and I am really excited to see that there is potential for life in the Uranian system,” she told BBC News. “I’m also so pleased that so much is being done with the Voyager data. It’s amazing that scientists are looking back at the data we collected in 1986 and finding new results and new discoveries”. Dr Affelia Wibisono of the Dublin Institute for Advanced Studies, who is independent of the research team, described the results as “very exciting”. “It shows how important it is to look back at old data, because sometimes, hiding behind them is something new to be discovered, which can help us design the next generation of space exploration missions”. Which is exactly what Nasa is doing, partly as a result of the new research. It has been nearly 40 years since Voyager 2 last flew past the icy world and its moons. Nasa has plans to launch a new mission, the Uranus Orbiter and Probe, to go back for a closer look in 10 years’ time. According to Nasa’s Dr Jamie Jasinski, whose idea it was to re-examine the Voyager 2 data, the mission will need to take his results into account when designing its instruments and planning the scientific survey. “Some of the instruments for the future spacecraft are very much being designed with ideas from what we learned from Voyager 2 when it flew past the system when it was experiencing an abnormal event. So we need to rethink how exactly we are going to design the instruments on the new mission so that we can best capture the science we need to make discoveries”. Nasa’s Uranus probe is expected to arrive by 2045, which is when scientists hope to find out whether these far-flung icy moons, once thought of as being dead worlds, might have the possibility of being home to life.

TruthLens AI Summary
Recent research has challenged the long-held belief that the moons of Uranus are lifeless and inactive. A new analysis indicates that the data collected by NASA's Voyager 2 spacecraft, which flew by Uranus nearly 40 years ago, may have been skewed due to a powerful solar storm occurring at the time of the flyby. This storm likely distorted the magnetic field and obscured any signs of geological activity or subsurface oceans that could support life. The findings suggest that the Uranian system could be more dynamic and interesting than previously thought, potentially harboring moons with conditions suitable for life, including the presence of subsurface oceans. Dr. William Dunn from University College London has emphasized that the new insights reveal a previously misunderstood environment around Uranus and its moons, opening up the possibility that these celestial bodies might be far more lively than the Voyager 2 data indicated.
The implications of this research extend beyond merely revising our understanding of Uranus. Linda Spilker, a scientist involved with the Voyager program, expressed excitement over the potential for discovering life in the Uranian system, highlighting the importance of revisiting and reanalyzing old data to uncover new findings. Such revelations are also influencing NASA's future exploration plans, including the proposed Uranus Orbiter and Probe mission, set to launch in the next decade. Dr. Jamie Jasinski from NASA noted that the upcoming mission will incorporate the insights gained from the Voyager 2 analysis to better design instruments for capturing crucial scientific data. With the probe expected to arrive by 2045, scientists are hopeful that this new mission will provide definitive answers about the moons of Uranus and their potential to support life, transforming our understanding of these distant, icy worlds.
