The Trifid Nebula, M20 Located about 5,200 ly away in the direction of Sagittarius, the Trifid Nebula is an unusual combination of star cluster, emission, reflection and dark nebulosity in a complex Milky Way field. It is a star-forming region that has already produced the
bright (multiple) star in the centre and the surrounding cluster of roughly 3100 stars. Deep infra-red images also reveal a number of protostars in the early stages of evolution. |
