Cosmic caterpillar is a mixture of interstellar gas and dust that extends to a light year in length. It has been captured by the Hubble telescope and resembles a caterpillar on its way to a feast. The celestial object has been observed at the Cygnus constellation, 4500 light years away. The head of the object is a protostar but the presence of 65 O-type stars, which tend to scatter the matter accumulated by the Cosmic caterpillar has scientists doubting if the caterpillar will mature into a star
