The irregular spiral galaxy NGC 5486 floats above a field of faint, distant galaxies in this photo taken by the NASA/ESA Hubble Space Telescope. The galaxy's thin disk is dotted with pink star formations that contrast with the diffuse glow of the galaxy's bright centre. Despite having indistinct, winding spiral arms, this particular galaxy is close to the Pinwheel Galaxy, one of the best-known examples of a spiral galaxy with a "grand design" and prominent, well-defined spiral arms. The largest and most accurate spiral galaxy image ever obtained with Hubble was the Pinwheel Galaxy, photographed by Hubble in 2006.
In the constellation Ursa Major is NGC 110, 5486 million light-years from Earth. This finding is based on a Hubble photo collection looking at Type II supernova remnants. As massive stars near the end of their lives, they release enormous volumes of gas and dust before detonating in massive supernova explosions. To learn more about these explosive events, astronomers used the sharp vision of Hubble's Advanced Camera for Surveys to study the supernova remnant in NGC 2004 in 5486.
