The Crab Nebula is cataloged as M1, the first on Charles Messier’s famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, an expanding cloud of debri...
2023年1月15日 M1: The Crab Nebula from Hubble Image Credit: NASA, ESA, Hubble, J. Hester, A. Loll (ASU) Explanation: This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. The filaments are not only tremendously complex, but appear to have less mass than expelled in th...
2022年8月21日 The Spinning Pulsar of the Crab Nebula Image Credit: NASA: X-ray: Chandra (CXC), Optical: Hubble (STScI), Infrared: Spitzer (JPL-Caltech) Explanation: At the core of the Crab Nebula lies a city-sized, magnetized neutron star spinning 30 times a second.

2021年10月22日 A Comet and a Crab Image Credit & Copyright: Jose Mtanous Explanation: This pretty field of view spans over 2 degrees or 4 full moons on the sky, filled with stars toward the constellation Taurus, the Bull. Above and right of center in the frame you can spot the faint fuzzy reddish appearance of Messier 1 (M1), also known as the Crab Nebula....
2021年02月09日 Flashes of the Crab Pulsar Video Credit & Copyright: Martin Fiedler Explanation: It somehow survived an explosion that would surely have destroyed our Sun. Now it is spins 30 times a second and is famous for the its rapid flashes. It is the Crab Pulsar, the rotating neutron star remnant of the supernova that created the Crab Nebula. A carefu...
