| Astronomy Picture of the Day: 2013 September 5 M1: The Incredible Expanding Crab
The Crab Nebula is on Charles Messier's list of astronomical phenomenas that are not comets. This nebula is known to be a remenant of a supernova, a cloud of debris continually spreading throughout the universe from the explosion of a massive star. The Crab Nebula was first observed around the year 1054. The nebula lies about 6,500 light-years away from the constellation Taurus.
The composure of the nebula and the movement of the explosion caught my attention when I first saw the Crab Nebula. The nebula looks like blue and red veins of a human, which makes me feel more in touch with the vast universe around me.
