Hello! Astronomy Picture of the Day - September 6th, 2020
Today's video is about M1: The Crab Nebula from Hubble
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 the original supernova and a higher speed than expected from a free explosion
The featured image, taken by the Hubble Space Telescope, is presentedi in three colors chosen for scientific interest
The Crab Nebula spans about 10 light-years
In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town
The Crab Pulsar rotates about 30 times each second
