Astronomers have used the unique capabilities of NASA's Hubble Space Telescope to peer closer than ever into the throat of an energetic monster black hole powering a quasar. A quasar is a galactic ...

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 ...

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 ...

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 ...

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 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 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 ...
