An Infrared View of the Trifid Nebula


The Trifid Nebula, aka M20, is easy to find with a small telescope. It’s a well known object in the nebula rich constellation Sagittarius. Visible light pictures show the nebula divided into three parts by dark, obscuring dust lanes, but this infrared image reveals filaments of luminous gas and newborn stars. This false-color view was taken by the Spitzer Space Telescope. The Trifid is about 30 light-years across and around 5,500 light-years away.
