Real Quasar

Astronomers have achieved an extraordinary milestone by capturing the closest and most detailed image of one of the universe's brightest objectsquasar 3C 273. Located 2.5 billion light-years away, this cosmic beacon is one of the closest quasars to Earth and an essential window into the mysteries of our universe. What Are Quasars and Why Do

The quotquasar windsquot are propelling hundreds of solar masses of material outward into the galaxy disk each year. This affects the entire galaxy as the material snowplows into surrounding gas and dust. NASA, ESA and J. Olmsted STScI The closest quasars to Earth are hundreds of millions of light-years away. Because of how much time it takes light

The term quasar was first used in an article by astrophysicist Hong-Yee Chiu in May 1964, in Physics Today, to describe certain astronomically puzzling objects 12. So far, the clumsily long name quotquasi-stellar radio sourcesquot is used to describe these objects. Because the nature of these objects is entirely unknown, it is hard to prepare a short, appropriate nomenclature for them so that

To give some idea of the luminosity of a quasar, scientists at the Mullard Space Science Laboratory at University College London describe how the nearest quasar, 3C 272, has a luminosity of 2.5 x

A newly discovered quasar is a real record-breaker. Not only is it the brightest quasar ever seen, but it's also the brightest astronomical object in general ever seen. It's also powered by the

This image from Hubble's Wide Field and Planetary Camera 2 WFPC2 is likely the best of ancient and brilliant quasar 3C 273, which resides in a giant elliptical galaxy in the constellation of Virgo The Virgin. Its light has taken some 2.5 billion years to reach us. Despite this great distance, it is still one of the closest quasars to our home. It was the first quasar ever to be

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 B1359154 6

Illustration of simulated Webb images of quasar and galaxy surrounding quasar. Researchers will take images of each target with Webb's Near-Infrared Camera NIRCam, like the simulated image shown at left. Next, they will remove the quasar's light to reveal the galaxy and its stars, simulated at right.

It was the first quasar ever to be identified, and was discovered in the early 1960s by astronomer Allan Sandage. The term quasar is an abbreviation of the phrase quotquasi-stellar radio source,quot as they appear to be star-like on the sky. In fact, quasars are the intensely powerful centers of distant, active galaxies, powered by a huge disc of

Using the European Southern Observatory's ESO Very Large Telescope VLT, astronomers have characterised a bright quasar, finding it to be not only the brightest of its kind, but also the most luminous object ever observed. Quasars are the bright cores of distant galaxies and they are powered by supermassive black holes. The black hole in this record-breaking quasar is growing in mass by
