Vol. 3: An Unfiltered View
Located about 6,500 light years in the distance, the Crab Nebula is the remnant of a massive star that exploded in 1054. Witnessed and documented by Chinese astronomers, the star was observed to be four times brighter than Venus and visible in the daytime sky for 23 days after it was first noticed.
Currently, it has grown to a diameter of about 10 light-years and is continuing to inflate at a rate of over 600 miles/second (1,500 km/s).
The colors in this image match what we would see if our eyes were much more sensitive and provide some insight into the composition of this spectacular stellar corpse. The red and pink filaments are the tattered remains of the star and consist mostly of hydrogen. The blue in the filaments in the outer part of the nebula represents oxygen.
This image was produced under Bortle 5- 6 skies.
