A team headed by Stefan Eisebitt has developed a new X-ray holography method that will enable snap-shots of dynamic processes at highest spatial resolution. The efficiency of the new method is based on a X-ray focussing optics being firmly fixed to the object to be imaged.
Every year, October is designated as American Archive Month. While many people may think “archive” means only dusty books and letters, there are, in fact, many other types of important archives. This includes the use of archives for major telescopes and observatories like NASA’s Chandra X-ray Observatory.
It is a mystery that has stymied astrophysicists for decades: how do black holes produce so many high-power X-rays?
Pulsars have a number of unusual qualities. Like zombies, they shine even though they’re technically dead, and they rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. A NASA team has built a first-of-a-kind testbed that simulates these distinctive pulsations.
Astronomers at NASA have used the Chandra X-Ray Observatory to conduct a detailed study of an enormous cloud of hot gas enveloping two large, colliding galaxies.
Scientists around the world are celebrating the 50th anniversary of X-ray astronomy this year. Few objects better illustrate the progress of the field in the past half-century than the supernova remnant known as SN 1006.
While performing an extensive X-ray survey of our galaxy's central regions, NASA's Swift satellite spotted the previously unknown remains of a shattered star.
Following a successful launch, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has begun its mission to discover secrets of buried black holes and other exotic objects.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) may be the size of a refrigerator, but it will undoubtedly help astronomers discover some of the most interesting aspects of our universe.
X-ray and ultraviolet observations from NASA's Swift satellite have given new infoprmation about the origins of Type Ia supernovae.
Department of Energy scientists have built the world's hottest laser, delivering temperatures hotter than the corona of the sun.
The mainstream media might not give it much coverage, but information has been slowly leaking out into the public sphere that airport body scanners could be dangerous to people who pass through them. They could be more dangerous than the government previously admitted.
The most powerful X-ray blast ever detected from deep space temporarily blinded NASA's Swift space observatory last month.
