The center section of the backplane structure that will fly on NASA's James Webb Space Telescope has been completed, marking an important milestone in the telescope's hardware development.
A new study by astronomers at NASA, Johns Hopkins University and the Rochester Institute of Technology suspicions about how stellar-mass black holes produce their highest-energy light.
NASA's Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now,NuSTAR results imply it went dormant.
By comparing infrared and X-ray background signals, team of astronomers has discovered evidence of a significant number of black holes that accompanied the first stars in the universe.
Astronomers at NASA and Pennsylvania State have used the Swift satellite to create the most detailed ultraviolet light surveys ever of the Large and Small Magellanic Clouds.
Astronomers using NASA's Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, yielding clues they can use to understand these extremely dense objects.
On March 29, 2012, the science team for NASA's Fermi Gamma-ray Space Telescope learned that a defunct Cold-War spy satellite would pass too close for comfort on April 4.
Astronomers have used NASA's Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch.
Three unusually long-lasting stellar explosions discovered by NASA’s Swift satellite represent a previously unrecognized class of gamma-ray bursts (GRBs).
An exploding star observed in 1604 by the German astronomer Johannes Kepler held a greater fraction of heavy elements than the sun, according to an analysis of X-ray observations from Suzaku.
NASA's Astrophysics Explorer Program has selected two missions for launch in 2017: a planet-hunting satellite and an International Space Station instrument to observe X-rays from stars.
NICER will gather scientific data revealing the physics of the densest matter allowed in nature, and could revolutionize our ability to travel to the far reaches of the solar system and beyond.
Astronomers from the University of Maryland at College Park (UMCP) and Lowell Observatory have used NASA's Swift satellite to check out comet C/2012 S1 (ISON).
While performing an extensive X-ray survey of our galaxy's central regions, NASA's Swift satellite has uncovered the previously unknown remains of a shattered star.
Two X-ray space observatories, NASA's NuSTAR and the European Space Agency's XMM-Newton, have teamed up to measure the spin rate of a black hole with a mass 2 million times that of our sun.
A new study using observations from Fermi reveals the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe.
The European Space Agency (ESA) has selected three NASA-nominated science teams to participate in their planned Euclid mission, including one led by Goddard Space Flight Center.
Engineers working on NASA's James Webb Space Telescope met another milestone recently with they completed performance testing on the observatory's aft-optics subsystem.
