Vivid glowing auroras in Jupiter's atmosphere! Astronomers are using the Hubble Space Telescope to study auroras - stunning light shows in a planet's atmosphere - on the poles of the largest planet in the solar system, Jupiter. This observation program is supported by measurements made by our Juno spacecraft, which arrives at Jupiter on Monday. While Hubble is observing and measuring the auroras on Jupiter, Juno is measuring the properties of the solar wind itself; a perfect collaboration between a telescope and a space probe.
Auroras are created when high-energy particles enter a planet's atmosphere near its magnetic poles and collide with atoms of gas. As well as producing beautiful images, this program aims to determine how various components of Jupiter's auroras respond to different conditions in the solar wind, a stream of charged particles ejected from the sun.
