SGR 1900+14

|- style="vertical-align: top;" | Distance |

SGR 1900+14, is located in the constellation of Aquila about 20,000 light-years away. It is an example of an intensely magnetic star, known as a magnetar, which is thought to arise from a fairly recent supernova explosion; only four are known to exist for certain within our Milky Way Galaxy. Could be a possible super-magnetic quark star.

NASA’s Spitzer Space Telescope detected a mysterious ring around SGR 1900+14 at two narrow infrared frequencies in 2005 and 2007. The 2007 Spitzer image showed no discernable change in the ring after two years. The ring measures seven light-years across. The origin of the ring is currently unknown and is the subject of an article in the May 29, 2008 issue of the journal Nature.
