Nasa’s Maven probe has analysed a new phenomenon in
the Martian atmosphere — an ultraviolet glow like the aurora
borealis on Earth.
Between 18 and 23 December 2014, the spacecraft observed an
auroral glow in the planet’s northern hemisphere. Aurorae have been
recorded on the planet before by Europe’s Mars Express
probe, but the aurora has never been spotted so deep in the
atmosphere.
