According to the latest findings, though black holes attract everything to their core, including light and radiation, they have an upper limit as far as their maximum mass goes. Yale astronomy and physics professor Priyamvada Natarajan believes that the largest black hole can't be more than 10 billion times the ... |

The Coma Cluster, or Abell 1656, is a spherical galactic cluster about 20 million light years across located at about 300 million light years towards the north pole of the Milky Way, meaning it is relatively easy to view from Earth since the dust and gas plane of the galaxy doesn't interfere. The cluster contain... |

Case Western Reserve University researchers using new charge coupled device instrumentation are now able to view deeper and wider in the night sky than previously thought possible. CCDs are highly sensitive light sensors similar to those used by today's digital cameras. The new device was designed and installed ... |

ESA's Very Large Telescope surprised what seems to be a group of three large galaxies engaged into gravitational interactions with each other. The system lies 106 million light years away, in the direction of the Piscis Austrinus constellation, and is formed of NGC 7173, NGC 7174 and NGC 7176. Two of the galaxie... |

It is a well known fact that galaxies can form new stars as they move through the space to join other galaxies in dense galaxy clusters which are pulled together by the powerful gravitational forces. Nevertheless, most of them tend to follow the gas filaments of dark matter that stretch between the galaxies. As they ... |

Astronomers were shocked to find that a known galaxy cluster has recently started emitting high amounts of X-ray and gamma ray light. Originally, they thought that such emissions could originate in the massive amounts of inert gas lying in intergalactic space, however ESA's Integral X-ray observatory has proven... |

Galaxy clusters are the biggest structures observed in the visible universe and while most of the times they are easy to spot and classify, apparently, some can evade detection by hiding behind other such huge clusters. This was the case of the galaxy cluster Abell 3128 that, when observed in the X-ray light spectrum... |
