Dead star and distant black holes dazzle in x-rays

Two new views from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, showcase the telescope's talent for spying objects near and far.

X-rays reveal inner structure of the Earth's ancient magma ocean

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.

NASA's Chandra sees eclipsing planet in X-rays for first time

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.

Pulsar shows puzzling behavior

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.

X-rays reveal how earliest animals moved

The first four-legged animals dragged themselves across the ground like seals, a reconstruction of their backbones has shown.

Galactic black hole emits massive flare

 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.

Massive Phoenix cluster forms stars at a record pace

Astronomers have identified an "extraordinary" galaxy cluster which scientists describe as one of largest objects in the universe.

Black hole emits massive X-ray burst

A population of old, volatile stellar black holes has been discovered, following an 'extraordinary outburst' from one located in a nearby galaxy.

Planet evaporates under fierce X-ray blasts

Astronomers at the Chandra X-ray observatory say they've observed a planet so close to an active star that it's evaporating.

Solar flares emit more radiation than thought - and one's due to hit tomorrow

NASA's Solar Dynamics Observatory has discovered new characteristics of solar flares - with great timing, as one's due to hit Earth tomorrow.

Opinion: More people should opt out of TSA scanners

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.

Obama wants to unscramble our private communications

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.

Team finds new class of black hole

Astronomers believe they've found a new type of black hole, following observations of the most extreme ultra-luminous X-ray source yet discovered.
