Description

Trifid Nebula

The Trifid Nebula, also known as M20, is a star-forming region in the plane of our own galaxy. Its name comes from the Latin word "trifid," meaning "divided into three lobes," as dark, obscuring dust lanes appear to divide it into three parts. These dark nebulae are identified as Barnard 82.

The entire Trifid Nebula is about the size of the full moon on our night sky, spans 40 light-years across, is approximately 300,000 years old, and lies about 5,000 light-years away from Earth in the nebula-rich constellation Sagittarius.
