Protostar IRAS 20324+4057 Eroded by UV Radiation from O-Type Stars Image
Visible is a light-year-long knot of gasses and dust resembling a caterpillar, protostar IRAS 20324+4057. The scene is set in the constellation Cygnus, eroded by UV radiation from distant O-type and B-type stars belonging to the Cygnus OB2 association. This photo taken using Hubble’s Advanced Camera for Surveys and other telescopes captures early star formation stages, making it suitable for astronomy research and educational content illustrating stellar evolution.
