Latest Supermassive black hole Stories
Astronomers have located one of the most powerful black holes ever discovered – a gravity-intense region of space that is located nearly four billion light years from Earth and has prevented trillions of stars from forming.
A pair of dazzling images from NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) highlights the observatory's impressive imaging capabilities for objects both near and far.
The Hubble Space Telescope has revealed a new image of the galaxy Messier 83, which has hosted a large number of supernova explosions and is believed to have a double nucleus at its core.
A new study based on data from NASA’s Spitzer Space telescope has revealed new details about so-called urban galaxies that exist in large clusters.
Our understanding of how some black holes consume matter might be changed by new observations of a black hole powering an energetic X-ray source in a galaxy some 22 million light years away.
NASA's Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today.
The NASA/ESA Hubble Space Telescope has captured the best ever image of the globular cluster Messier 15, a gathering of very old stars that orbits the center of the Milky Way.
A team of NASA scientists have found an 'ultra-compact dwarf galaxy' that may be the densest galaxy ever discovered.
A worldwide network of radio telescopes has allowed astronomers to find strong evidence that a powerful jet of material is blowing massive amounts of gas out of the host galaxy.
Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...
Black Hole -- Black holes are objects so dense that not even light can escape their gravity. They are believed to form from the gravitational collapse of astronomical objects containing two or more solar masses. Astronomical observations suggest that the center of most galaxies, including our own Milky Way, contain supermassive black holes containing millions to billions of solar masses. Black holes are predictions of Einstein's theory of general relativity. In particular, they occur...
