Beautiful image of the Crab Nebula in the constellation Taurus, about 5,000 light-years from Earth.
Roughly 12 light-years in diameter, it is the remnant of a supernova, first observed by Chinese and other astronomers in 1054, that was visible in daylight for 23 days and at night for almost two years.
