Due to the special gravitational lens effect where light is bent as it passes heavy objects, such as galaxy clusters, a group of physics students at the Niels Bohr Institute observed a quasar whose ...

'This does not look right': Scientists accidentally measure ultrahot ring around black hole using rare 'double zoom' technique
For the first time, astronomers have directly measured a solar-system-size corona around a distant supermassive black hole, ...
For the first time, astronomers have seen the image of a distant quasar split into multiple images by the effects of a cloud of ionized gas in our own Milky Way Galaxy. Such events were predicted as ...
Jan. 23 (UPI) --The Hubble constant is the rate at which the universe is expanding. Through the decades, astronomers have developed more reliable ways to estimate the value of the Hubble constant, but ...
Quasars are the bright centers of young galaxies powered by supermassive black holes. Most quasars are very distant and faint, making them difficult to observe. One quasar, 0957+561, is ...
The most unique feature in a new image taken with the NASA/ESA Hubble Space Telescope is a group of five quasar images produced by a process called gravitational lensing, in which the gravitational ...
Using the ESO 3.6-m telescope at La Silla (Chile), an international team of astronomers 1 has discovered a complex cosmic mirage in the southern constellation Crater (The Cup). This "gravitational ...
With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic “lens” and split into four similar images.

Hubble Telescope sees 'weird things' in closest-ever look at a quasar from monster black hole
The Hubble Space Telescope has peered deeper than ever before into the heart of the supermassive black hole-powered quasar 3C, 273 spotting "weird" structures.
Four of the newfound quadruply imaged quasars are shown here: From top left and moving clockwise, the objects are: GraL J1537-3010 or "Wolf's Paw;" GraL J0659+1629 or "Gemini's Crossbow;" GraL ...
The Cloverleaf quasar, a 17th-magnitude object, exhibits quadruply lensed images due to gravitational lensing by an intervening galaxy. X-ray observations reveal brightness discrepancies among the ...
