APOD 4.7

A Beautiful Trifid
2011 May 13

This is in space.  The fact that this beauty exists in space is interesting enough.  This is a Trifid Nebula. It is also known as M20.  It lies about 5000 light years from Earth in the nebula scattered constellation Sagittarius which lies at the center of our galaxy.  This picture represents three different kinds of nebulas (reflection, dark, and emission nebulae) all centered in this M object which is where it gets its name: Trifid.  It is about 40 light years across.
