A very huge black hole was removed from the center of the galaxy by powerful gravitational waves.
Scientists have measured an object located around a black hole 5 billion light-years from Earth.
Apparently a distant and quiet quasar SDSS J1011+5442 has run out of gas.
Using the ALMA space telescope, researchers found that the most luminous galaxy in the universe is experiencing violent turbulence and it is eating away itself.
Two supermassive black holes may be about to smash together in the constellation Virgo.
Researchers have made an unusual discovery. They've found two supermassive black holes in Markarian 231, which is the nearest quasar to Earth.
Scientists have made a huge step forward for physics. Scientists have produced the best ever constraint of the gravitational constant measured outside of our solar system.
Astronomers have discovered a giant, swirling disk of gas that represents a galaxy being born. The forming galaxy is actively being fed cool primordial gas that traces back to the Big Bang.
NASA has taken a closer look at the "teenage years" of quasars. Using the Hubble Space Telescope, astronomers have uncovered the early formative years of the brightest objects in the universe.
Using the Hubble Space Telescope's infrared vision, astronomers have unveiled some of the previously hidden origins of quasars, the brightest objects in the universe.
Scientists have discovered a set of wispy, green objects that are the ghosts of quasars that flickered to life and then faded away.
Astronomers have spotted an unusual alignment spread across our universe. They've discovered 93 quasars that have formed huge groupings spread over billions of light-years at a time when the universe was at a third of its current age.
