Astronomers have found a galaxy turning gas into stars with almost 100 percent efficiency, a rare phase of galaxy evolution that is the most extreme yet observed. The findings come from the IRAM Plateau de Bure interferometer in the French Alps, NASA’s Wide-field Infrared Survey Explorer and NASA’s Hubble Space Telescope.
The tiny red spot in this image is one of the most efficient star-making galaxies ever observed, converting gas into stars at the maximum possible rate. The galaxy is shown here in an image from NASA’s Wide- field Infrared Survey Explorer (WISE), which first spotted the rare galaxy in infrared light.
