Amazing Crab Nebula
The Crab Nebula, the result of a supernova noted by Earth-bound chroniclers in 1054 A.D., is filled with mysterious filaments that are 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 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.

Radiographs are able to reveal the interior of the human body by sending rays that can pass through matter toward a photographic plate with a subject in between. Bones absorb the passage of these rays much more effectively than skin muscle and tissue. Therefore only certain rays reach the plate and a kind of negative image is produced when the film is developed. xray of hip femur joint pelvis leg abdomen colored
