Motion in the Crab Nebula
This time-lapse movie of the Crab Nebula, made from NASA Hubble Space Telescope observations, reveals wave-like structures expanding outward from the "heart" of an exploded star. The waves look like ripples in a pond.
The heart is the crushed core of the exploded star, or supernova. Called a neutron star, it has about the same mass as the sun but is squeezed into an ultra-dense sphere that is only a few miles across and 100 billion times stronger than steel. This surviving relic is a tremendous dynamo, spinning 30 times a second. The rapidly spinning neutron star is visible in the image as the bright object just below center. The bright object to the left of the neutron star is a foreground or background star.
The movie is assembled from 10 Hubble exposures taken between September and November 2005 by the Advanced Camera for Surveys.

Changes in the Crab Nebula
This NASA Hubble Space Telescope image reveals how wave-like structures unleashed by the powerful remnant of a dead star move outward over time in the heart of the Crab Nebula. The surviving remnant is the collapsed core of a burned-out star, and is called a neutron star. This...
