Composite image from the Hubble Space Telescope and the Isaac Newton Telescope showing a caterpillar-like protostar (IRAS 20324+4057) at an early stage in its formation. The object lies 4500 light-years away in the constellation Cygnus. This massive trailing cloud of gas is in the process of collapsing under its own gravity to form a star. However,powerful stellar radiation from numerous hot bright stars to the right of the image (known as the Cygnus OB2 association) is eroding the gas cloud,blasting it into its distinctive shape | |
