Video: V838 Monocerotis Dissolve Sequence of Epochs

Running Time: 24 seconds

A dissolve sequence of eight images taken by Hubble's Advanced Camera for Surveys shows a CAT-scan-like probe of the three-dimensional structure of the shells of dust surrounding the aging star V838 Monocerotis. The sequence reveals dramatic changes in the way a brilliant flash of light from the star is reflecting off surrounding dusty cloud structures. The effect, called a light echo, has been unveiling never-before-seen dust patterns ever since the star suddenly brightened for several weeks in early 2002.
