Three Chandra Views of Cassiopeia A
QuickTime
MPEG
This sequence shows three different sets Chandra observations of
Cassiopeia A. The first image is Chandra's "First Light" image, which
was released in August 1999 as the observatory's first major science
image. This 5,000-second-long observation then dissolves into another
image created from Chandra that contained data from 50,000 seconds of
X-ray data released in 2002. Finally, the new one-million-second
observation of Cassiopeia A is seen, revealing spectacular new detail
and complexity to the supernova remnant.

Supernova Remnant Animation

When a massive star explodes, it creates a shell of hot gas that glows
brightly in X-rays. This animation shows this process and depicts the
stellar debris that Chandra is able to observe, revealing the dynamics
of the explosion. In the case of Cassiopeia A, astronomers believe this
star originally exploded approximately 320 years ago.
