Notes:
|
The Crab nebula is a cloud of gas ejected by a star that exploded(supernova) on July 4, 1054. It was observed and recorded by Chinese astronomers. It was 4 times the brightness of Venus (mag -6) and visible during daylight for 23 days and at night for 653. The gas is expanding at a rate of 1,800 km/sec |
| It contains also contains a Pulsar (dense neutron star), which emmits a strong radio source as it rotates at 30 times per second. It has 100,000 times the energy of our sun and it is so dense that it contains our suns entire mass in just 30 kilometers of it's surface. | |
