Why some galaxies have become barren

Why some galaxies have become barren

Over the last few billion years, a mysterious kind of galactic warming has caused many galaxies to change from a lively place where new stars formed every now and then to a quiet place devoid of fresh young stars.

The jet, found in the system known as B3 0727+409, is at least 300,000 light years.  

Black holes could grow as large as 50 billion Suns: Study

Black holes could grow as large as 50 billion Suns: Study

The only way it could get larger is if a star happened to fall straight in or another black hole merged with it.

Scientists find supermassive black holes in nearest quasar Markarian 231

Scientists find supermassive black holes in nearest quasar Markarian 231

A team of astrophysicists and astronomers, led by Dr Youjun Lu of the National Astronomical Observatories of China, has found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.

Five 'supermassive' black holes discovered

Five 'supermassive' black holes discovered

Five supermassive black holes that were previously hidden by clouds of dust and gas have been discovered by astronomers who suggest that millions of concealed monster black holes exist in the universe.

Pulsing light reveals supermassive black hole merger

Pulsing light reveals supermassive black hole merger

As two galaxies enter the final stages of merging, their supermassive black holes form a “binary” or two black holes that are gravitationally bound to one another. Now, astronomers from University of Maryland have found direct evidence of a pulsing quasar which may substantiate the existence of black hole binaries.

How stars, galaxies formed in early Universe

A new study has provided a deeper insight into how stars and massive galaxies formed in the infancy of our Universe.

How supermassive black holes interact with host galaxies

Astronomers have discovered strange and unexpected behavior around the supermassive black hole at the heart of the galaxy NGC 5548.

Active supermassive black holes discovered in merging galaxies

A team of astronomers have found at least one supermassive black holes almost always becomes active and luminous by accreting a large amount of material in luminous, gas-rich, merging galaxies.

How supermassive black holes are formed

Over billions of years, small black holes can slowly grow supermassive by taking on mass from their surroundings and also by merging with other black holes.

How supermassive black holes grow when galaxies collide

Experts have claimed that the notion black holes become supermassive by merging with other black holes is much more complex than previously believed.

NASA`s NuSTAR spacecraft detects 10 supermassive black holes

NASA`s new black-hole-hunter spacecraft - NuSTAR - has detected its first 10 supermassive black holes, lying at the hearts of distant galaxies between 0.3 and 11.4 billion light-years from Earth.

`Supermassive` black holes may be bigger than thought

Some of the biggest black holes in the universe may actually be even bigger than previously thought, a study that uses data from NASA’s Chandra X-ray Observatory has suggested.

NASA’s WISE telescope discovers millions of supermassive black holes

NASA’s Wide-field Infrared Survey Explorer (WISE) mission has uncovered millions of new supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies.

Cosmic climate change in early universe `may have stunted black holes`

The early universe, which was warmed by the greediest of black holes, could have stunted the growth of the rest, a new study has revealed.

Black holes `eat binary star partners` to grow

There are two ways to grow a supermassive black hole: with gas clouds and with stars.

`Life may be possible in supermassive black holes`

Supermassive black holes are known to be absolutely uninhabitable and the most destructive force in space.
