 On April 22, 2010, during the celebration of the 20th anniversary of the Hubble Space Telecope, NASA released the image above, describing it as "a pillar of gas and dust three light-years tall being eaten away by the brilliant light from nearby bright stars."   This cosmic pinnacle lies within the Carina Nebula, located 7,500 light-years away.  Not far at all, considering that the Milky Way Galaxy measures 100,000 light years in diameter.
