NASA discovered a remote galaxy shining with the light of more than 300 trillion suns. It is the most luminous galaxy found to date and belongs to a new class of objects recently discovered by the Wide-field Infrared Survey Explorer (WISE) – extremely luminous infrared galaxies.
A newfound galaxy 12.5 billion light-years from Earth is the most luminous one known in the universe, blazing more brightly than 300 trillion suns, a new study reports.
The engine behind the galaxy’s brilliance may be a supermassive black hole, researchers said. Such behemoths lurk at the heart of most, if not all, galaxies; material spiraling down into the black holes’ maws heats up tremendously, emitting huge amounts of light in visible, ultraviolet and X-ray wavelengths.
