NASA’s Swift satellite has secured a new high-resolution ultraviolet image of the Milky Way’s sister Andromeda galaxy, exposing some 20,000 ultraviolet sources such as hot young stars and star clusters. Compare the image above with the visible light image below.

At 2.5 million light years distant from our own galaxy, Andromeda is more than 220,000 light years across. For more details on this image and its implications see this item at the NASA/Goddard Space Flight Center website or this summary at Science Daily.
