Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.

Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter.

Astronomers with the Sloan Digital Sky Survey (SDSS) announced that a distant quasar ran out of gas.

Astronomers have used the Hubble Space Telescope's infrared vision to uncover the mysterious early formative years of quasars, the brightest objects in the universe.

NASA's Hubble Space Telescope has photographed a set of wispy, goblin-green objects that are the ephemeral ghosts of quasars that flickered to life and then faded.

Quasars are galaxies with very active supermassive black holes at their centres.

A team of astronomers have observed a distant gravitationally-lensed quasar (i.e., an Active Galactic Nucleus;) with the Subaru Telescope and concluded that the data indeed present a 3-D view of the structure around a quasar.

At the ends of the Universe there are black holes with masses equaling billions of our sun. These giant bodies - quasars - feed on interstellar gas, swallowing large quantities of it non-stop.

Quasars Used for Deep Space Missions

Deep-space missions require precise navigation, in particular when approaching bodies such as Mars, Venus or a comet. How precise?

A Dartmouth-led team of astrophysicists has discovered the extent to which quasars and their black holes can influence their galaxies.

Hubble astronomers have looked at one of the most distant and brightest quasars in the universe and are surprised by what they did not see: the underlying host galaxy of stars feeding the quasar.
