Space Image of the Day Gallery (January 2016)

Ultraviolet Scene

Canada-France-Hawaii Telescope/Coelum

Friday, Jan. 29, 2016: Emission nebula IC 4628 lies about 6,000 light years away in the constellation of Scorpius. These types of nebulas arise when a sun-like star at the end of its life spews forth an enormous amount of gas. The remaining star, a white dwarf, emits intense ultra-violet light that causes the gas to glow, with different elements of the gas displaying different colors. Red indicates ionized hydrogen, and near the central star, doubly ionized oxygen glows in green. IC 4628 also goes by the names of the Prawn Nebula and Gum 56. Image released December 2015.
