Protostar IRAS 20324+4057 Zoom Sequence
This video begins with a view of the stars in the constellation Cygnus. We zoom into the Cygnus OB2 association region, and then into a Hubble view of protostar IRAS 20234+4057. This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast.
