Experts with the European Space Agency (ESA) say that the their Herschel Space Observatory has recently been used to demonstrate that the most active supermassive black holes at the cores of galaxies tend to impair stellar formation within the structures they occupy.
This discovery may highlight an interaction and f... |

A collaboration of astronomers from the University of Utah and the Harvard-Smithsonian Center for Astrophysics (CfA) found in a new study that supermassive black holes can grow by disrupting the gravitational interactions between two stars in a binary system, and then consuming one of them.
Over the years, experts h... |

Astronomers announce the discovery of cosmic gas clouds formed around supermassive black holes. These formations are not falling through the event horizon, as many expected, but rather are produced by the matter that should be consumed.
The reason this is interesting is that some of the matter that was supposed to ... |

Using data from a number of telescopes, experts were recently able to snap a new view of the galaxy cluster Abell 2052. The formation is of interest because the massive gas clouds it contains display a sloshing-like motion, similar to how a liquid wobbles inside a glass when moved.
Investigators used visible-light ... |

A quick look at the large-scale distribution patterns of matter in the Universe will reveal the existence of what astronomers plastically refer to as the cosmic web.
It is made up of thick tendrils of gas that come together at node, and apparently this is where supermassive black holes prefer to develop.
This act... |

A recent study has demonstrated that massive galaxies, structures larger even than the Milky Way is now, existed very early on in the history of the Universe, perhaps as little as 1.5 to 2 billion years after the Big Bang. According to the research, these galaxies may have been 5 to 10 times more massive than our own... |
