Stunning Images of Saturn’s Auroras
via Slash Gear
Striking new images from the Hubble Space Telescope have revealed the vast auroras fluttering atop its North Pole, the best shots ever captured of the glowing halo. The new images are in fact an amalgamation of seven months of capture by Hubble, and are already giving astronomers the opportunity for new insights into the light shows.
Hubble captured the images in ultraviolet light through seven months in 2017, using its Space Telescope Imaging Spectrograph. That combines a camera with a spectrograph, allowing a single instrument to record everything across the spectrum from near-infrared through to ultraviolet. It’s already been used to record groundbreaking images of black holes in distant galaxies.
