Latest Supermassive black hole Stories
It’s very difficult to kick a star out of the galaxy. In fact, the primary mechanism that astronomers have come up with that can give a star the two-million-plus mile-per-hour kick it takes requires a close encounter with the supermassive black hole at the galaxy’s core.
Idan Ginsburg, a graduate student in Dartmouth's Department of Physics and Astronomy, studies some of the fastest moving objects in the cosmos.
Black holes that grow to masses billions of times greater than that of our sun most likely reached those sizes by consuming objects from multiple locations at the same time.
Harvard-Smithsonian Center for Astrophysics researchers have determined that some planets are flying around in space at 30 million miles per hour.
Astronomers have clocked the fastest wind yet ever discovered blowing off a disk around a stellar-mass black hole.
Astronomers, using the Hubble Space Telescope, say they have found a black hole that was once at the core of a now-disintegrated dwarf galaxy.
Astronomers are building a virtual telescope as big as our planet that will capture the first ever picture outlining an enormous black hole within our 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...
