Intense radiation from a quasar in one of these galaxies alters the gas properties in the other galaxy and dampens its ability to form new stars, according...
The newly-discovered radio jet spans an astonishing 215,000 light-years, and is associated with J1601+3102, an extremely radio-loud quasar that existed...
Astronomers using the Dark Energy Spectroscopic Instrument (DESI), a state-of-the-art instrument mounted on NSF’s Nicholas U. Mayall 4-m telescope at...
Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Subaru Telescope, astronomers have discovered a pair of merging gas-rich galaxies...
A quasar called RX J1131-1231 resides approximately 6 billion light-years away in the constellation of Crater.
This Webb image shows the RX J1131-1231...
Astronomers have discovered a pair of merging quasars seen only 900 million years after the Big Bang. Not only is this the most distant pair of merging...
To study dark energy’s effects over the past 11 billion years, the Dark Energy Spectroscopic Instrument (DESI) has created the largest 3D map of our...
The new map, dubbed Quaia, includes around 1,295,502 quasars from across the visible Universe and could help astronomers better understand the properties...
The black hole in the newly-discovered quasar SMSS J052915.80-435152.0 (hereafter called J0529-4351) accretes around one solar mass per day onto an existing...
Markarian 817 is a Seyfert 1 galaxy located 430 million light-years away in the constellation of Draco. Also known as Mrk 817 or QSO J1436+5847, it hosts...
Observations of quasars reveal that many supermassive black holes were in place less than 700 million years after the Big Bang. However, the origin of...
Galaxies are strung along filaments in the vast cosmic web, which also contains enormous voids. Using the NASA/ESA/CSA James Webb Space Telescope, astronomers...
A fundamental consequence of the relativistic picture of expanding space is cosmological time dilation, where events in the distant Universe appear to...
Only a few hundred million years after the Big Bang, the infant Universe was brimming with opaque hydrogen gas that trapped light at some wavelengths from...
Using the NASA/ESA Hubble Space Telescope and other space and ground-based observatories, astronomers have discovered SDSS J0749+2255, a closely bound...
Astronomers using the NASA/ESA Hubble Space Telescope have taken a beautiful picture of the luminous spiral galaxy Z 229-15, which is found in the constellation...
3C 297 is located about 9.2 billion light-years away in the constellation of Virgo and contains a quasar, a supermassive black hole pulling in gas at the...
