Latest Perseus Cluster Stories
Using the ESA’s XMM-Newton and NASA’s Chandra X-ray Observatory, astronomers have located a mysterious X-ray signal that could be produced by sterile neutrinos – particles that are a potential candidate for the abundant and essentially invisible substance known as dark matter.
A Naval Research Laboratory scientist is part of a team that has recently discovered that vast clouds of hot gas are "sloshing" in Abell 2052, a galaxy cluster located about 480 million light years from Earth.
X-ray observations made by the Suzaku observatory provide the clearest picture to date of the size, mass and chemical content of a nearby cluster of galaxies.
A gigantic sonic boom generated by a supermassive black hole has been found with NASA's Chandra X-ray Observatory, along with evidence for a cacophony of deep sound.
Scientists using NASA's Chandra X-ray Observatory have discovered evidence of energetic plumes â€“ particles that extend 300,000 light years into a massive cluster of galaxies. The plumes are due to explosive venting from the vicinity of a supermassive black hole.
Astronomers have found the most powerful eruption seen in the Universe using NASA's Chandra X-ray Observatory. A supermassive black hole generated this eruption by growing at a remarkable rate. This discovery shows the enormous appetite of large black holes, and the profound impact they have on their surroundings.
