Astronomers have used the unique capabilities of NASA's Hubble Space Telescope to peer closer than ever into the throat of an energetic monster black hole powering a quasar. A quasar is a galactic ...

This image, taken with the Atacama Large Millimeter/submillimeter Array (ALMA), shows the molecular gas content of two galaxies involved in a cosmic collision. The one on the right hosts a quasar –– a ...

Using the Spektr-RG (SRG) space observatory, astronomers from the Russian Academy of Sciences have inspected a radio-loud quasar known as SRGA J2306+1556, which is extremely luminous in the X-ray band ...

A Hubble Space Telescope image of the core of quasar 3C 273. A coronagraph on Hubble blocks out the glare coming from the supermassive black hole at the heart of the quasar. This allows astronomers to ...

The Hubble Space Telescope captures the closest look yet at the host galaxy of a quasar. Credit: NASA / ESA / Bin Ren / Joseph DePasquale The Hubble Space Telescope captured some weird, unidentified ...

Quasars acting as strong gravitational lenses are among the rarest finds in astronomy. Out of nearly 300,000 quasars cataloged in the Sloan Digital Sky Survey, only twelve candidates were identified, ...

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...

Compelling evidence that the structure of matter surrounding supermassive black holes has changed over cosmic time has been uncovered by an international team of astronomers. If true, the research led ...
