Latest Galaxies Stories
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.
Astronomers have discovered a new black hole candidate sitting inside a globular cluster known as M62.
During the last few hundred years, the dim region very close to the supermassive black hole near the center of the Milky Way flared up with at least two luminous outbursts, according to a team of researchers using NASA's Chandra X-ray Observatory.
At the center of almost every galaxy we have studied is a black hole of such magnitude that the traditional black hole progenitor does not seem likely. These aptly named supermassive black holes can reach millions or billions of times the mass of our Sun.
Astronomers using a "Virtual Observatory" set out to study "fat" black holes that grow up to more than one million solar masses.
New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) in the high-altitude Atacama Desert of Chile have revealed new details about the powerful molecular-gas jets that stream out of supermassive black holes.
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...
