Planetary scientists believe they can now predict the green glow of an aurora in the night sky above Mars, and they have the images to prove it. The first observations of a visible-light aurora from the surface of the Red Planet were made by NASA’s Perseverance Mars rover in 2024. Now, presenting at the Europlanet Science Congress–Division of Planetary Science (EPSC–DPS) joint meeting in Helsinki this week, Dr Elise Wright Knutsen of the University of Oslo will reveal a second snapshot of the aurora by Perseverance and, more importantly, the tools to predict when an aurora will occur on Mars.
A new AI-powered tool has reduced astronomers’ workload by 85% - filtering through thousands of data alerts to identify the few genuine signals caused by supernovae (powerful explosions from dying stars). The findings have been published today (10 Sept) in The Astrophysical Journal.
