M42-Orion nebula, plus Running man nebula
This is a large nebula in the constellation Orion. It can be seen with binoculars in the middle of the sword (hanging from the belt). It's about 1400 light years away, one of the nearest star forming regions to earth. A compact group of 4 bright stars called the Trapezium is the primary light source for this nebula. The Trapezium is just visible in this image, in the whitest part of the nebula. The red color is light emitted by ionized hydrogen (H-alpha). The blue color is blue light from massive blue stars, reflected by dust grains.
