A Storm of Stars in the Trifid Nebula
A storm of stars is brewing in the Trifid nebula, as seen in this view from NASA’s Wide-field Infrared Survey Explorer, or WISE. The stellar nursery, where baby stars are bursting into being, is the yellow-and-orange object dominating the picture. Yellow bars in the nebula appear to cut a cavity into three sections, hence the name Trifid nebula.
The blue stars scattered around the picture are older, and they lie between Earth and the Trifid nebula. The baby stars in the Trifid will eventually look similar to those foreground stars. The red cloud at upper right is gas heated by a group of very young stars. The Trifid nebula is located 5,400 light-years away in the constellation Sagittarius.
