My Correct Views on Everything

M82 Detail

The ESA’s Hubble website released this detailed view of the centre of Messier 82, a starburst galaxy 12 million light-years away in the constellation Ursa Major. M82 is a very well-known galaxy: I’ve seen it myself through the telescope; it makes a pretty pair with the nearby spiral galaxy Messier 81, interactions with which are triggering the outbreak star formation that is characteristic of a starburst galaxy. This is a view of M82’s core, through hydrogen-beta, sulphur-II and oxygen-III emission filters and in the ultraviolet. See also this Hubble wide-field view from 2006 and this composite view in the visual, infrared and X-ray bands. Image credit: ESA/Hubble and NASA.
