Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. EGGs, short for evaporating gaseous globules , are dense regions of mostly molecular hydrogen gas that fragment and gravitationally collapse to form stars . Light from the hottest and brightest of these new stars heats the end of the pillar and causes further evaporation of gas - revealing yet more EGGs and more young stars. This picture was taken by the Wide Field and Planetary Camera on board the Hubble Space Telescope .
