‘Like Salt Sprinkled on Black Velvet’ Hubble Captures Dwarf Galaxy UGC 5497

The NASA/ESA Hubble Space Telescope has captured this view of the dwarf  galaxy UGC 5497, which looks a bit like salt sprinkled on black velvet in this image.

The object is a compact blue dwarf galaxy that is infused with newly formed clusters of stars. The bright, blue stars that arise in these clusters help to give the galaxy an overall bluish appearance that lasts for several million years until these fast-burning stars explode as supernovae.

UGC 5497 is considered part of the M 81 group of galaxies, which is located about 12 million light-years away in the constellation Ursa Major (The Great Bear). UGC 5497 turned up in a ground-based telescope survey back in 2008 looking for new dwarf galaxy candidates associated with Messier 81.

goal of the mission is to help scientists zoom in on solar activity such as

sunspots, solar flares and coronal mass ejections, thus improving forcasts of

solar storms.
