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. The engine behind the galaxy's brilliance may be a supermassive black hole, researchers said.

Researchers using the Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured new images of a ring of gas and dust seven light-years in diameter surrounding the supermassive black hole at the center of the Milky Way, and of a neighboring cluster of extremely luminous young stars embedded in dust cocoons.
Largest water reservoir discovered in black hole. The reservoir holds as much as 140 trillion oceans, or more than 4,000 times more than exists in the entire Milky Way. It exists as vapour spread across hundreds of light years. While water has been found across much of the universe previously, this is interesting because of the fact this reservoir is 12 billion light years away, meaning that this water existed when the universe was only 1.6 billion years old.
