The Green Bank Telescope sees a Yeti

Date:17 September 2014 Tags:, , , , , ,

This composite radio-optical image shows five new clouds of hydrogen gas discovered using the Green Bank Telescope (GBT). The spiral galaxy M81 and its satellite, M82, are seen in visible light (white), the new hydrogen gas is coloured red, and additional hydrogen gas earlier detected by the Very Large Array is shown in green. The M81 Group of galaxies, some 11,8 million light-years from Earth, are interacting gravitationally with each other, as shown by the gas streaming among them.
