This handout photo provided by NASA, taken April 12, 2010 by the Hubble Space Telescope, shows an unusual, ghostly green blob of gas appears to float near a normal-looking spiral galaxy. NASA released Monday the Hubble Space Telescope’s first picture of the mysterious giant glowing green blob of gas called Hanny’s Voorwerp. The blob is the size of our Milky Way galaxy and is 650 million light years away. Each light year is about 6 trillion miles. The blob was discovered in 2007 by Dutch school teacher Hanny van Arkel.
