Submission + - 'Green' Galaxy Recycles Gas, Supercharges Star Birth (discovery.com)

astroengine writes: In a galaxy, far, far away (6 billion light-years away to be precise), the most efficient star "factory" has been discovered. Called SDSSJ1506+54, this galaxy generates a huge quantity of infrared radiation, the majority being generated by a compact region at its core. NASA's Wide-field Infrared Survey Explorer (WISE) first spotted the galactic oddity and Hubble confirmed the maelstrom of stellar birthing near its core. But the most amazing thing? This galaxy is the "greenest" factory yet discovered — it uses 100 percent of all the available hydrogen to supply the protostars, leaving no waste. “This galaxy is remarkably efficient,” said lead scientist Jim Geach of McGill University in a NASA news release. “It’s converting its gas supply into new stars at the maximum rate thought possible.”
