Cosmic Pillar in Eagle NebulaThis NASA/ESA Hubble Space Telescope image features a towering structure of billowing gas in the Eagle Nebula (Messier 16). The pillar rises 9.5 light-years tall and is 7,000 light-years away from Earth. Spiral galaxy Messier 77, also called the Squid Galaxy, sits 45 million light-years away in the constellation Cetus (The Whale). CREDIT: ESA/Hubble & NASA, A. Nota, P. Massey, E. Sabbi, C. Murray, M.
