Hubble captures vivid image of aurora on Jupiter
The Hubble Space Telescope has captured an image from Jupiter’s north pole that could give the Giant Red Spot a challenge as the planet’s most spectacular feature.
Using the Hubble's ultraviolet sensing equipment, researchers have captured an aurora bigger than all of Earth.
The image was released by the European Space Agency on Thursday and is actually a composite of two shots. The first is an optical shot taken by Hubble in spring 2014 and the second comes from its ultraviolet sensors and was taken this year.
Attention is focused on Jupiter this week as the solar-powered Juno spacecraft is on the final leg of a five-year, 1.8 billion-mile voyage to the biggest planet in the solar system.
As Juno approaches Jupiter late Monday, it will fire its main rocket engine to slow down and slip into orbit around the planet.
