New observations with the Subaru Telescope, a Japanese 8-m telescope on Mauna Kea, Hawaii, show that aurorae at Jupiter’s poles are heating the atmosphere...
From the ground, the dance of the northern lights, or aurora borealis, can look peaceful. But those shimmering sheets of colored lights are the product...
Viewing Saturn’s northern polar region for a period of seven months, the NASA/ESA Hubble Space telescope snapped a series of stunning images of auroras...
