Hubble Space Telescope Evaporating Gaseous Globules (EGGs) in the Eagle Nebula, Emerging from Pillars of Molecular Hydrogen Gas and Dust 1995
These giant pillars are light years in length and are so dense that interior gas contracts gravitationally to form stars. At each pillars’ end, the intense radiation of bright young stars causes low density material to boil away, leaving stellar nurseries of dense EGGs exposed. The Eagle Nebula, associated with the open star cluster M16, lies about 7000 light years from earth.
“…From our home on the Earth, we look out into the distances and strive to imagine the sort of world into which we are born… . But with increasing distance our knowledge fades, and fades rapidly, until at the last dim horizon we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be suppressed.” Edwin Hubble, last paragraph of his last published scientific paper, ‘The Law of Red Shifts (George Darwin Lecture),’ Monthly Notices of the Royal Astronomical Society, 1953
