The active galaxies and the feeding supermassive black hole-powered quasars are seen as they were when the universe was less than one billion years old. When you purchase through links on our site, we ...
A pair of quasars that existed when the universe was only 3 billion years old has been spotted by the Hubble Space Telescope.
A team of astrophysicists say quasars, some of the most brilliant phenomena in the universe, are likely caused by collisions between galaxies. Quasars are a type of active galactic nuclei; they lurk ...
April 5 (UPI) --Astronomers have discovered a pair of quasars indicating the merging of a pair of galaxies, according to a report published Wednesday in the journal Nature. These high-energy quasars ...
In a recent study published in Nature, a team of researchers have used a combination of NASA’s Hubble Space Telescope and ground-based observations to examine a pair of gravitationally bound quasars ...
Supermassive black holes lurk at the centers of massive galaxies, including our own Milky Way. Puzzlingly, supermassive black ...
recent survey conducted by a research team headed by Dr. Mark Lacy, an astronomer at the Space Infrared Telescope Facility Science Center in Pasadena. The team will display its report on June 3 at the ...
Astronomers using the Hubble Space Telescope and other observatories have discovered a pair of gravitationally-bound quasars inside two merging galaxies. Quasars are active and luminous types of ...
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. The glowing structures have looping, ...
The hearts of some galaxies glow so brightly that they are given a special name: Quasars. Powered by supermassive black holes at the center of these galaxies, these regions give off tremendous amounts ...
Twinkling like cosmic lighthouses on a shore 13 billion light-years from Earth, quasars are some of the oldest, brightest relics of the early universe that astronomers can detect today. Short for ...
