Astronomers using the Hubble Space Telescope and other observatories have discovered a pair of gravitationally-bound quasars inside two merging galaxies. Quasars are active and luminous types of ...

NASA’s Hubble Space Telescope is “seeing double.” Peering back 10 billion years into the universe’s past, Hubble astronomers found a pair of quasars that are so close to each other they look like a ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. That means studying 3C 273 has been like staring into the headlights of an oncoming car for ...

Astronomers have used the Hubble Space Telescope’s infrared vision to uncover the mysterious early formative years of quasars, the brightest objects in the universe. Hubble’s sharp images unveil ...

Credit: NASA /ESA / Kristina Nyland, et al. Quasars are among the most extreme objects in the cosmos, shining so brightly that the US Navy uses them as navigational beacons. US Naval Academy student ...

This artist’s concept shows the brilliant glare of two quasars residing in the cores of two galaxies that are in the chaotic process of merging. The gravitational tug-of-war between the two galaxies ...

A two-panel image of quasar 3C 273, taken by different Hubble instruments. The top panel is a WFPC2 image of 3C 273. It looks like a bright white car headlight. There's a linear orange-white ...

In a recent study published in Nature, a team of researchers have used a combination of NASA’s Hubble Space Telescope and ground-based observations to examine a pair of gravitationally bound quasars ...

The Hubble Space Telescope captures the closest look yet at the host galaxy of a quasar. Credit: NASA / ESA / Bin Ren / Joseph DePasquale The Hubble Space Telescope captured some weird, unidentified ...

The early universe was a rambunctious place where galaxies often bumped into each other and even merged together. Using NASA's Hubble Space Telescope and other space and ground-based observatories, ...

A Hubble Space Telescope image of the core of quasar 3C 273. A coronagraph on Hubble blocks out the glare coming from the supermassive black hole at the heart of the quasar. This allows astronomers to ...
