May 30, 1996: Probing the mysterious heart of the Crab Nebula, the tattered remains of an exploding star, astronomers have found this object to be even more dynamic than previously understood. These findings are based on a cosmic "movie" assembled from a series of Hubble telescope observations.
The sequence of pictures is giving astronomers a remarkable look at the dynamic relationship between the tiny Crab pulsar — the collapsed core of the exploding star — and the vast nebula of dust and gas that it powers.

Surrounding the pulsar is a complex of sharp knots and wisp-like features.See the rest:
