Two new views from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, showcase the telescope's talent for spying objects near and far.
Using the world's most brilliant X-ray source, scientists have for the first time peered into molten magma at conditions of the deep Earth mantle. The analysis at DESY's light source PETRA III revealed that molten basalt changes its structure when exposed to pressure of up to 60 gigapascals (GPa), corresponding to a depth of about 1400 kilometres below the surface.
For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.
Astronomers are baffled by the discovery of a pulsar - a tiny spinning stars, heavier than the sun and smaller than a city - that emits different types of radiation at different times.
The first four-legged animals dragged themselves across the ground like seals, a reconstruction of their backbones has shown.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has taken its first look at the giant black hole at the center of our galaxy - and caught it right in the middle of a flare-up.
Astronomers have identified an "extraordinary" galaxy cluster which scientists describe as one of largest objects in the universe.
A population of old, volatile stellar black holes has been discovered, following an 'extraordinary outburst' from one located in a nearby galaxy.
Astronomers at the Chandra X-ray observatory say they've observed a planet so close to an active star that it's evaporating.
NASA's Solar Dynamics Observatory has discovered new characteristics of solar flares - with great timing, as one's due to hit Earth tomorrow.
The president of the Allied Pilots Association is urging to pilots to opt out of the naked body scanners, which are also known as Advanced Imaging Technology (AIT). This mass opposition to TSA porno scanners is one of the first steps in the right direction.
America has been known as the military–industrial complex for decades now, so it’s not surprising that the post 9/11 national security state has created big brother problems.
Astronomers believe they've found a new type of black hole, following observations of the most extreme ultra-luminous X-ray source yet discovered.
