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).
This quasar's luminosity is, therefore, about 4 trillion (4 × 10 12) times that of the Sun, or about 100 times that of the total light of giant galaxies like the Milky Way. [49] This assumes that the quasar is radiating energy in all directions, but the active galactic nucleus is believed to be radiating preferentially in the direction of its jet.
RX J1131-1231 is the name of the complex, quasar, host galaxy and lensing galaxy, together. 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. Cloverleaf: 4 [3] Brightest known high-redshift source of CO emission [4] QSO B1359+154: 6
Each black circle and red cross on the upper image map is a quasar similar to this one. The Huge Large Quasar Group , ( Huge-LQG , also called U1.27 ) is a possible structure or pseudo-structure of 73 quasars , referred to as a large quasar group , that measures about 4 billion light-years across.
3C 279 (also known as 4C–05.55, NRAO 413, and PKS 1253–05) is an optically violent variable quasar (OVV), which is known in the astronomical community for its variations in the visible, radio and X-ray bands. [2] The quasar was observed to have undergone a period of extreme activity from 1987 until 1991. [3]

In 1993, Thomson et al. suggested that the (outer) jet of the quasar 3C 273 is nearly collinear to the Earth's line-of-sight. Superluminal motion of up to ~9.6c has been observed along the (inner) jet of this quasar. [5] [6] [7] Superluminal motion of up to 6c has been observed in the inner parts of the jet of M87.
