NGC 1579    Northern Trifid Nebula

NGC 1579 is a small (around 12 arc-min diameter), bright emission and reflection nebula in the constellation Perseus. It has a physical size of around 3 LY across and is located around 2100 LY away. The nebula is surrounded by dark clouds of obscurring dust. These dark clouds hide the star that actually lights this nebula. The star, designated LkHα 101, is a very young and massive star with very strong Hα emissions. It is the largest of a group of around 35 young stars embedded in the nebulosity and dust of this object. The dark dust in this region give the nebula its common name— the "Northern Trifid Nebula." Dark lanes in front of the bright portion of this nebula appear to divide it up into pieces in a manner reminiscent of M 20, the Trifid Nebula in Sagittarius.
NGC 1579 was discovered by William Herschel in 1788. It also has the designation Sharpless 222.
