Scientists have linked supernovae to the heating of the Milky Way's outer gas layer, revealing a cosmic dance of creation and destruction that shapes our galactic environment. Scientists may have unco ...

Quasars are awe-inspiring – among the brightest objects in the Universe, behind gamma-ray bursts and supernovae. Unlike other ...

Looking at a distant galaxy means looking back in time.

Astronomers used a coronograph, an instrument on the Hubble Space Telescope, to blot out the blindingly bright light of the quasar so they could study its surroundings. Credit: NASA / ESA Black ...

For the first time, a new study confirms that circumgalactic medium (CGM) doesn’t just contain “hot gases enriched in oxygen” ...

NASA's Hubble Space Telescope has unveiled the closest-ever look at a monster black hole devouring its cosmic surroundings. This supermassive black hole, at the heart of a quasar known as 3C 273 ...

In simple terms, the quasar is very, very bright. Hubble’s Space Telescope Imaging Spectrograph (STIS) can work as a coronograph, and is used to block light from central sources. Astronomers ...

Quasar is short for "quasi-stellar radio source" — bright, star-like objects that emit radio waves and are powered by actively feeding supermassive black holes. The first quasars were identified ...
