The quasar's host galaxy is also lensed into a Chwolson ring about the lensing galaxy. The four images of the quasar are embedded in the ring image.

3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2] The derived distance to this object is 749 megaparsecs (2.4 billion light-years).
Artist's impression of QSO J0439+1634. Note the prominent blue hue. QSO J0439+1634, [4] often referred to by just its coordinates, J0439+1634 or J043947.08+163415.7, [1] is a superluminous quasar, and was, until 20 February 2024, (when it was superseded by QSO J0529-4351) considered the brightest quasar in the early universe with a redshift of z = 6.51.
The unusually bright quasar is located 13 billion light-years away and experts say the discovery could unlock clues about our universe’s early beginnings. The brightest celestial object in the ...
Sloan Digital Sky Survey image of quasar 3C 273, illustrating the object's star-like appearance. The quasar's jet can be seen extending downward and to the right from the quasar. Hubble images of quasar 3C 273. At right, a coronagraph is used to block the quasar's light, making it easier to detect the surrounding host galaxy.
Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. The black hole ...
This suggests the quasar is currently undergoing an intense wave of star formations thus increasing its luminosity. [3] A radio jet has also been found on the side of quasar according to a study published in 2023. [5] CCD image of the Cloverleaf quasar taken in March 1988 by the ESO/MPI 2.2m telescope. The four separated images are part of the ...
APM 08279+5255 was initially identified as a quasar in 1998 during an Automatic Plate Measuring Facility (APM) survey to find carbon stars in the galactic halo.The combination of its high redshift (z=3.87) and brightness (particularly in the infrared) made it the most luminous object yet seen in the universe.
