Latest Galaxies Stories
As astronomers peer out into the distant reaches of the Universe they find that some galaxies are emitting enormous amounts of radiation from their cores.
Scientists affiliated with NASA’s NuSTAR and XMM-Newton X-ray observatories have now devised a clever way to directly measure the rotation of nearby supermassive black holes.
Black holes are voracious monsters at the center of galaxies that shape the growth and death of the stars around them with their tremendous gravitational pull and explosive ejections of energy. Now, researchers are using them as a tool to probe the limits of spacetime.
On large astronomical scales, gravity remains the dominant force acting on heavenly bodies. But when it comes to young clusters of stars, researchers say these crowded environments cannot be fully accounted for by a simple view of gravity.
Astronomers using NASA's Chandra X-ray Observatory claim that matter was ejected at high speeds along the poles of a rotating star, creating a supernova remnant, W49B, which may contain a young black hole.
In today's Your Universe Today Podcast, we talked with theoretical physicist Dr. Kelly Holley-Bockelmann about mysterious supermassive black holes, which are millions or billions times larger than our Sun.
New research published in the Astrophysical Journal suggests black holes are growing at larger rates than what had previously been thought possible.
Black holes of any size are mysterious, seemingly breaking through the barriers of the physical laws that guide our Universe.
On today’s Your Universe Today podcast, theoretical physicist Dr. Kelly Holley-Bockelmann is back to discuss facts about black holes and help us separate myth from reality.
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...
