Resting on the tail of the Great Bear in the constellation of\u00a0Ursa Major, lies NGC 5585, a\u00a0spiral galaxy\u00a0that is more than it appears.<\/p>\n

The many stars, and dust and gas clouds that make up NGC 5585, shown here in this Hubble image, contribute only a small fraction of the total mass of the galaxy. As in many galaxies, this discrepancy can be explained by the abundant yet seemingly invisible presence of\u00a0dark matter.<\/p>\n

The stellar disc of the galaxy extends over 35 000\u00a0light-years\u00a0across. When compared with galaxies of a similar shape and size, NGC 5585 stands out by having a notably different composition: Contributing to the total mass of the galaxy, it contains a far higher proportion of dark matter.<\/p>\n

Hotspots of star formation can be seen along the galaxy\u2019s faint spiral arms. These regions shine a brilliant blue, contrasting strikingly against the ever-black background of space.<\/p>\n
