Using several ground- and space-based telescopes, astronauts were recently able to capture the most impressive view ever of the supermassive black hole that powers up the galaxy Centaurus A.
Also known as NGC 5128, the prominent space structure is located in the constellation of Centaurus. Estimates on the distanc... |

Supermassive black holes are mostly found in galactic nuclei, ejecting matter in the form of particle jets at relativistic speeds during the 'feeding' process. According to theory, these particle jets are accelerated to these speeds by tightly-twisted magnetic fields generated in the close proximity of the ... |

It is a well known fact that black holes can spin with extreme speeds, yet new observations conducted with NASA's Chandra X-ray Space Telescope reveal that supermassive black holes could even reach rotation speeds close to the upper limits allowed in the space-time fabric. Not only that, but physicists also pro... |

The newly discovered pre-main sequence young star HH211, located in the Perseus constellation at a distance of about 1,000 light years from Earth, represents the first solid evidence that stars dispose of angular momentum not only by emitting large gas jets from its poles and shedding part of its upper layers, but a... |
