NASA's Hubble space telescope has recently helped astronomers stumble upon a very unlikely duo. One of the smallest galaxies ever identified has been discovered to be the home of a super massive black hole.
Experts have been fairly certain for a long time that there are two sizes for black holes, small and incredibly colossal. Now however, researchers claim to have identified medium-sized black holes, a potential phenomenon that has long been shrouded in confusion and doubt.
In the spirit of the 4th of July, scientists are talking about the dazzling light show that's currently happening in the nearby galaxy Messier 106, as seen by NASA's Spitzer Space Telescope, Chandra X-ray Observatory and the Herschel Space Observatory.
Three closely orbiting supermassive black holes have been discovered billions of light years away. Groups like this are theorized to be the source of gravitational waves in the Universe, according to the theory of General Relativity.
Astronomers have been able to identify some unusual activity coming from a black hole not too far away from Earth. This supermassive black hole appears to have started emitting a stream of gas, providing new insight into how black holes act and interact with their surroundings.
New research shows that despite contrary belief, the gravitational fields around black holes might eddy and swirl, adding a bit extra bumpiness.
NASA observations have identified that blazars - the highest-energy type of active galaxy in the universe - can run off of two unusual types of massive black holes that appear to collect gas, only to fire some of it out in jet streams that almost approach the speed of light.
As it turns out, the magnetic fields of supermassive black holes have an unexpected presence, their strength evenly matching the gravitational force produced by the black hole, according to a team of scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, Germany.
NASA's Wide-field Infrared Survey Explorer (WISE) surveyed more than 170,000 supermassive black holes, and their findings have taken a bite out of astronomers' long-held "doughnut" theory.
A new video, released by NASA, shows two super-dense neutron stars destroy each other in a cataclysmic cosmic merger event that eventually creates a black hole.
The newly discovered "hypervelocity star" may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious dark matter surrounding the galaxy, astronomers report.
Scientists at the European Space Agency’s Herschel space observatory announced Tuesday their observations of the black hole located at the center of the Milky Way as it appears to be devouring a feast of molecular gas, according to a press release issued by the organization.
Astronomers from University of California Los Angeles (UCLA) have discovered a star orbiting a black hole in just 11.5 years at the center of the Milky Way galaxy.
