APM 08279-5255 is a massive black hole (quasar) that contains about 140 trillion times the amount in all of Earth’s oceans ...

A team of researchers from EPFL have found a way to use the phenomenon of strong gravitational lensing to determine with precision – about 3 times more precise than any other technique – the mass of a ...

For roughly half a century, astrophysicists have treated the behavior of matter around supermassive black holes as a solved ...

Space monsters that are all mouth lurk in the depths of every galaxy, but where did supermassive black holes emerge from, other than the particle accelerator in The Black Hole? NASA’s Hubble Space ...

The first-ever sighting of starlight from a galaxy hosting one of the most distant quasars known has revealed an astronomical oddity. Quasars — blazingly bright galactic cores — owe their brilliance ...

Which came first: supermassive black holes, or the galaxies that orbit them? Recent observations of a distant quasar with no apparent host galaxy and a nearby companion galaxy suggest that it is ...

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. The ...

A space telescope has spotted astrange, distant galaxycluster with a cosmic heart that is surprisingly cold. NASA's Chandra X-ray Observatorysnapped an image of thecluster, which is about 8 billion ...

Astronomers have discovered a new class of “cold quasars” that could change our perception of how galaxies mature. The discovery was announced June 12 at the annual meeting of the American ...
