Astronomers Discover 19 New Quasars Using DESI Legacy Surveys Data
Using data from the DESI Legacy Surveys photometry catalog, 19 new quasars were identified, including strongly-lensed, dual, and projected types. Observations were carried out on October 15–16, 2023, at California's Palomar Observatory using the P200/DBSP instrument. Among the findings are two lensed quasars, J0746+1344 and J2121-0826, which exhi...

Hubble Captures Closest View of Quasar 3C 273, Revealing Mysterious Structures
The Hubble Space Telescope has provided an unprecedented view of quasar 3C 273, one of the brightest objects in the universe, unveiling mysterious features near its core. These include an L-shaped structure and blobs, likely smaller galaxies feeding the quasar’s black hole. The discovery also highlights a massive jet spanning 300,000 light-years ...

Hubble Offers Closest Look at Quasar 3C 273, Reveal Hidden Structures
NASA’s Hubble Space Telescope has captured unprecedented views of quasar 3C 273, located 2.5 billion light-years away. Using the STIS coronagraph, researchers uncovered unusual structures around the black hole, including an extragalactic jet and a mysterious L-shaped filament. The findings hint at galaxy interactions fuelling the quasar’s activ...

James Webb Space Telescope Finds First Evidence of Einstein Zig-Zag Phenomenon In a Distant Quasar
Data from the James Webb Space Telescope has revealed the first-ever Einstein zig-zag, where light from quasar J1721+8842 bends through two distinct warped space-time regions. Six mirrored images of the quasar and a faint Einstein ring confirm this rare lensing effect. Scientists believe this discovery could help resolve critical issues in cosmolog...

James Webb Space Telescope Spots Massive Black Hole With Half the Mass of Its Surrounding Galaxy
A groundbreaking discovery has been made with the identification of a remarkably massive black hole in the quasar ULAS J1120+0641. This black hole, with a mass of 1.4 billion solar masses, constitutes nearly half of the total mass of its host galaxy. Observations were made using the James Webb Space Telescope, which provided unprecedented detail in...

JWST Spots Isolated Supermassive Black Hole-Powered Quasars in the Early Universe
A team using the James Webb Space Telescope has discovered supermassive black hole-powered quasars in unexpectedly isolated environments. These lonely quasars, some of the earliest in the universe, present a mystery as they lack the dense surroundings that current theories suggest are needed for black hole growth. This discovery is pushing scientis...
