A team of astronomers using the W. M. Keck Observatory in Hawaii has discovered that aurorae at visible lengths appear on all four of Jupiter’s major moons, namely Io, Europa, Ganymede, and Callisto. The discovery was made using the High-Resolution Echelle Spectrometer (HIRES) at the Keck Observatory, as well as other high-resolution spectrographs at the Large Binocular Telescope and Apache Point Observatory.
A team of international researchers has made a major discovery about aurora activity on Jupiter. Their study supports the previously controversial idea that Jupiter's polar cap is threaded in part with closed magnetic field lines and proves the lights hold clues…
ESA and NASA space telescopes have revealed that, unlike Earth’s polar lights, the intense auroras seen at Jupiter’s poles unexpectedly behave independently of one another. Auroras have been seen in many places, from planets and moons to stars, brown…
Scientists on NASA's Juno mission have observed massive amounts of energy swirling over Jupiter's polar regions that contribute to the giant planet's powerful auroras – only not in ways the researchers expected. Examining data collected by the…
A previous Picture of the Day published in late 2012 quoted Jonathan Nichols from the University of Leicester:“The main aurora oval on Jupiter we think should dim when the solar wind blows harder, but what we see is that actually gets brighter, which is totally
