Latest Galaxies Stories
At the center of the Milky Way lurks a supermassive black hole known as Sagittarius A*, with some four million times the mass of our Sun. More than any single object, it has the greatest impact on the formation, evolution and fate of our galaxy.
A new analysis from scientists at NASA's Jet Propulsion Laboratory (JPL) revealed that supermassive galaxies have stopped cannibalizing their neighbors over the past few billion years.
A supermassive black hole is believed to sit at the center of each large galaxy and a new technique designed to detect the dark abyss's spin could be the key to unraveling a galaxy's history.
New observations have given a group of astronomers the best view yet of how star formation regions can get selfish and gassy.
The European Southern Observatory's Very Large Telescope has helped astronomers catch a supermassive black hole ripping apart a gas cloud for the first time.
Astrophysicists from the Astronomical Observatory of the Faculty of Physics at the University of Warsaw say the next collision of monstrous stars will not occur until billions of years from now.
Astronomers using a telescope attached to a modified Boeing 747SP aircraft have captured new images of a ring of gas and dust seven light-years in diameter surrounding the supermassive black hole at the center of the Milky Way.
Observations of a nearby active galaxy using the Very Large Telescope Interferometer (VLTI) at ESO’s Paranal Observatory in Chile have shown astronomers something they hadn’t expected to see.
Astronomers from several institutions have used decades-worth of collected data to confirm theories about how stellar-mass black holes produce their highest-energy light known as hard X-rays.
Astronomers have discovered an unprecedented number of black holes in the Andromeda Galaxy (M31), one of the Milky Way’s nearest cosmic neighbors, using data from NASA’s Chandra X-ray Observatory.
Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
