NGC 6514 / M20 Trifid Nebula

NGC 6523 / M8 Lagoon Nebula

Sagittarius

                                                                                                     

 

The Trifid Nebula was named by John Herschel over 200 years ago 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 to each other to be seen in this image.  To one side of the emission nebula, a faint blue reflection nebula can be seen.  This wide field view shows both the Trifid and the large Lagoon Nebula.  Both nebulae are parts of the same cloud of gas harboring star formation about 5,200 light years away.  West is down in this image.
