The brightest stars in the Hyades cluster form a V shape that marks the head of the celestial bull. The cluster lies along the same line of sight as Aldebaran, the brightest star in Taurus, but the bright giant is not a member of the cluster and lies much closer to Earth.

Trifid Nebula – Messier 20

  • by

The Trifid Nebula, also known as Messier 20 (M20), is a large star-forming region located in the southern constellation Sagittarius.

The nebula’s name means “divided into three lobes,” and refers to the object consisting of three types of nebulae and an open star cluster. The open cluster is surrounded by an emission nebula, a reflection nebula, and a dark nebula within the emission nebula that gives M20 the trifurcated appearance for which it is known.

The dark nebula was catalogued by Edward Barnard and has the designation Barnard 85 (B85). The Trifid Nebula has the designation NGC 6514 in the New General Catalogue.
