NASA’s Chandra X-ray Observatory has detected an extensive halo of hot gas around the spiral galaxy known as NGC 5746. There’s a sense of relief among scientists, as the discovery supports the theory that galaxies like our Milky Way are still accumulating matter from the gradual inflow of intergalactic gas. The halo encompassing the immense […]
Galactic collisions are common phenomena, according to Yale astronomer, Pieter van Dokkum, who used hundreds of images from two of the deepest sky surveys ever conducted to conclude that more than half of the largest galaxies in the nearby universe have collided and merged with another galaxy in the past two billion years. Cosmologists believe […]
David Merritt, a professor of physics at the Rochester Institute of Technology (RIT), has just finished putting together one of the fastest supercomputers in the world. The new computer uses a novel architecture to reach speeds much higher than that of standard supercomputers of comparable size, and is the first ever designed specifically to study […]
