M20 Trifid Nebula

Sagittarius

                                                                                                   

 

The Trifid Nebula was named over 200 years ago by John Herschel to describe its tri-lobed appearance.  A bright young triple star at the center of the Trifid excites and illuminates the surrounding hydrogen clouds.  The three components of the triple star are too close too each other to distinguish in this image.  Above the emission nebula a fainter blue reflection nebula is seen.  The star forming Trifid Nebula is 5,200 light years away.
