The Hubble Space Telescope is celebrating its 36th anniversary in space this week with a glimpse into the heart of a major star-forming region, presented in prismatic color.
The Trifid Nebula (also known as Messier 20) is one of the most famous objects in the night sky, attracting amateur astronomers to its location in the constellation of Sagittarius the Archer, set against myriad stars of the Milky Way. Hubble's new view of the Trifid is somewhat different from what skywatchers can see from Earth: the space telescope's 2.4-meter (8-foot) mirror is able to see much closer and in far more detail than any telescope on the ground is capable of achieving.
