Latest Galaxies Stories
A pair of Australian astrophysicists has shown that the shape of a galaxy is determined by how fast it spins, according to a new report in The Astrophysical Journal.
Typically filled with only the oldest stars, which are relatively low in mass and appear red, giant elliptical galaxies have long baffled astronomers. These galaxies are mysteriously shut down with respect to star-forming activity
An international team of astronomers used NASA’s Rossi X-ray Timing Explorer (RXTE) satellite data and found huge clouds of gas orbiting supermassive black holes.
Exploring the universe's most violent events using computer simulations is what Enrico Ramirez-Ruiz does. So in 2012, when the first detailed observations of a star being ripped apart by a black hole were reported in Nature, Ramirez-Ruiz was eager to compare the data to his simulations.
Just weeks after NASA’s Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A (Cen A, for short).
In what is being described as landmark discovery about the origins of the universe, Tel Aviv University researchers report in the journal Nature that black holes, formed from the first-ever stars, heated the gas throughout space much later than previously believed.
Astronomers writing in the Astrophysical Journal say that massive galaxies in the early universe were formed through collisions.
Astronomers publishing a paper in the Astrophysical Journal say they have found that two merging galaxies have active supermassive black holes.
Astronomers have located one of the most powerful black holes ever discovered – a gravity-intense region of space that is located nearly four billion light years from Earth and has prevented trillions of stars from forming.
The black hole in question is orbiting an object known as a Be-type star, which is unusual because of its incredibly high rate of rotation.
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...
