NASA, Citizen Scientists Discover Potential New Hunting Ground for Exoplanets Via a NASA-led citizen science project, eight people with no formal training in astrophysics helped discover what could be a fruitful new place to search for planets outside our solar system – a large disk of gas and dust encircling a star known as a

Hubble, Chandra, Jansky VLA Telescopes Collaborate on Galaxy Cluster In October 2013 Hubble kicked off the Frontier Fields program, targeting six massive galaxy clusters, enormous collections of hundreds or even thousands of galaxies. MACS J0717, shown here, is one of the most complex galaxy clusters known, the result of four galaxy clusters colliding.
Solar Storms Ignite X-ray « Northern Lights » on Jupiter Solar storms are triggering X-ray auroras on Jupiter that are about eight times brighter than normal over a large area of the planet and hundreds of times more energetic than Earth’s ‘northern lights,’ according to a new study using data from NASA’s Chandra X-ray Observatory.
Hubble Looks Into a Cosmic Kaleidoscope This cosmic kaleidoscope of purple, blue and pink marks the site of two colliding galaxy clusters.
Chandra Movie Captures Expanding Debris from a Stellar Explosion Astronomers have observed the debris field from this explosion − what is now known as Tycho’s supernova remnant − using data from NASA’s Chandra X-ray Observatory, the NSF’s Karl G. Jansky Very Large Array (VLA) and many other telescopes.
Chandra Finds Evidence for Violent Stellar Merger Gamma-ray bursts, or GRBs, are some of the most violent and energetic events in the Universe. Although these events are the most luminous explosions in the universe, a new study using NASA’s Chandra X-ray Observatory, NASA’s Swift satellite and other telescopes suggests that scientists may be missing a
A Black Hole Story Told by a Cosmic Blob and Bubble Two cosmic structures show evidence for a remarkable change in behavior of a supermassive black hole in a distant galaxy.
Supernova Ejected from the Pages of History A new look at the debris from an exploded star in our galaxy has astronomers re-examining when the supernova actually happened.
Young Magnetar Likely the Slowest Pulsar Ever Detected Using NASA’s Chandra X-ray Observatory and other X-ray observatories, astronomers have found evidence for what is likely one of the most extreme pulsars, or rotating neutron stars, ever detected.
X-ray Telescopes Find Evidence for Wandering Black Hole Astronomers have used NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton X-ray observatory to discover an extremely luminous, variable X-ray source located outside the center of its parent galaxy. This peculiar object could be a wandering black hole that came from a small galaxy falling into a larger
