Latest Galaxies Stories
A supersonic jet of material that looks amazingly similar to the afterburner flow of a fighter jet is blasting over two million light-years from the center of a distant galaxy.
Scientists have determined that the black hole in the middle of the Milky Way is getting ready to devour an approaching cloud of dust and gas.
Scientists have discovered a new population of supermassive black holes in the early universe by using infrared surveys.
A new stellar-mass black hole has been discovered in our galaxy by NASA's Swift satellite. High-energy X-rays emanating from a source towards the center of our Milky Way galaxy were observed, indicating the presence of a previously unknown black hole.
Astronomers, using the Keck Observatory, have found the star they need to test Einstein's theory about the fabric of space-time.
A surprising black hole discovery made while using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) is causing scientists to change what they know of globular star clusters.
Einstein predicted gravitational waves almost 100 years ago. According to his theory, whenever massive objects interact, they produce distortions in the very fabric of space and time that ripple outward across the universe at the speed of light.
Astronomers suggest, in the Astrophysical Journal Letters, as galaxies formed in the early universe, they were accompanied by fireworks in the form of energy bursts.
An international team of astronomers was able to measure the radius of a black hole for the first time.
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...
