NGC 1999

NGC 1999.

The dark T shaped object was once assumed to be an obscuring dark cloud seen in silhouette against the bright reflection nebula. However now it is believed to be a hole blown through the nebula itself by energetic young stars.

NGC 1999 is in the constellation of Orion, close to M42, its distance is approx. 1500 light years and shines from the light of a variable star on the edge.

In this dramatic scene there is IC 427, reflection nebula (below) and IC 428 (bottom), plus many Herbig-Haro (HH) objects.
