Lagoon and Trifid, Once More
July 25nd, 2017
In the heart of the Milky Way lies the Lagoon and Trifid, Messier 8 and 20. The Lagoon (right) is a large area of pink hydrogen emission, visible with the naked eye on summer nights and easily observable with binoculars. The Trifid, named for it’s lobed appearance, consists of a pink hydrogen area, criss-crossed by dark dust and surrounded by blue gas reflecting the young stars in the area. Messier 21 is the young open cluster on the left.
