X-rays offer a unique insight into the astronomical world. Invisible to the naked eye, most commonly they are thought of as the semi-dangerous source of medical scans. However, X-ray observatories, like the
Chandra X-ray Observatory are capable of seeing astronomical features that no other telescope can. Recently scientists found some of those X-rays coming from a relatively unexpected source –
Uranus.
While the data might have been found only recently, it was actually collected almost 2 decades ago in 2002, and then again in 2017. Despite the age of the data, scientists have a decent theory on what might be causing most of the observed
X-rays.
