In case you thought Jupiter couldn’t get any cooler, a paper in the Journal of Geophysical Research has laid out evidence that solar storms are causing Jupiter’s auroras (think the Northern Lights, the Southern Lights, or that scene from Brother Bear) to brighten by almost eight times their usual brilliance.
The interaction was spotted by NASA’s Chandra X-ray Observatory, a telescope orbiting above the Earth to look for X-ray emissions in that big, old universe of ours.
Since Jupiter’s auroras are actually X-ray auroras, they can’t be spotted by the typical telescope (or by the human eye, if any of you were hoping to plan future vacations there). Chandra was able to observe key changes in Jupiter’s X-ray auroras when a particularly wicked solar storm, or coronal mass ejection (CME), hit Jupiter.
