Latest Galaxies Stories
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.
Black holes are known to either come in masses of only about 10 times that of our sun, or the equivalent in mass of up to 10 billion suns. However, NuSTAR could be finally finding a middle ground.
Many supermassive black holes emit a jet of high-energy particles as a byproduct of engulfing large quantities of mass and energy, and NASA researchers have just discovered that the supermassive black hole at the center of the Milky Way is no different.
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.
Astronomers have long wondered exactly what the enigmatic jets given off by black holes are made of. Now, an international team of scientists, writing in the journal Nature, has apparently solved the mystery and discovered the composition of those high-speed beams of matter.
Astronomers have discover a new black hole candidate sitting inside a globular cluster known as M62.
Black holes are massive objects in space that have gravitational forces so strong that not even light can escape them. These objects, swirling at the centers of galaxies, also come in a variety of sizes.

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...
