Hubble observes energetic lightshow at Saturn's north pole [heic1815]

3 September 2018 - 9:33am

Astronomers using the NASA/ESA Hubble Space Telescope have taken a series of spectacular images featuring the fluttering auroras at the north pole of Saturn. The observations were taken in ultraviolet light and the resulting images provide astronomers with the most comprehensive picture so far of Saturn's northern aurora.

Stars v. Dust in the Carina Nebula
