NASA's Webb telescope captures mesmerizing images of Jupiter's auroras

The James Webb Space Telescope, NASA’s successor to the Hubble Space Telescope, has captured new images of the auroras at Jupiter’s north pole. These massive auroras, caused by charged particles crashing into Jupiter’s atmosphere, are hundreds of times brighter than our own Aurora Borealis, and, for the first time, we can now see them in greater detail thanks to these new images. Auroras on Earth are caused by solar storms, which occur when charged particles from the Sun collide with our upper atmosphere. This energizes the gases in the atmosphere, which gives them that distinctive colored glow that we know as the Northern (or Southern) Lights. Among the coolest things we’ve gleaned from the telescope’s observations is that particles from solar storms are not the only source for Jupiter’s auroras. The giant planet’s strong magnetic field is also pulling in charged particles from its surroundings, which includes particles thrown into the atmosphere from volcanic eruptions on Io, a moo ...
