Planets Beware: NASA Unburies Danger Zones of Star Cluster

Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiationwhich can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets. A team of astronomers used NASA’s Chandra X-ray Observatoryin combination with […]

NASA’s Chandra Finds Galaxy Cluster That Crosses the Streams

Astronomers using NASA’s Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure. Researchers have discovered an enormous, comet-like tail of hot gas — spanning over 1.6 million light-years long — trailing behind […]
