Hurt (SSC) New evidence from NASA’s Spitzer Space Telescope shows that supermassive black holes at the centers of elliptical galaxies keep the galactic “thermostat” so high gas cannot cool, stunting the birth of new stars. For the first time ever, astronomers have detected dust grains mingling with blazing hot gas at temperatures of 10 million degrees Kelvin (about 10 million degrees Celsius, or 17 million degrees Fahrenheit), in an area surrounding the elliptical-shaped galaxy called NGC 5044. Scientists hope this new finding will provide insight into how supermassive
