Using data from NASA's Swift and NuSTAR spacecraft, as well as from ESA's XMM-Newton satellite, Indian astronomers have investigated spectral and temporal properties of an ultraluminous X-ray source (ULX) in the spiral galaxy ...
Using XMM-Newton and Swift space telescopes, Chinese astronomers have inspected short-term X-ray variability of a tidal disruption event known as Swift J1644+57. Results of the study, published August 12 on the arXiv pre-print ...
Italian astronomers have performed X-ray observations of an ultraluminous X-ray source (ULX) known as NGC 4559 X7 and found that this source exhibits unusual flaring activity. The finding is reported in a paper published ...
This image shows a new type of star that has never been seen before in X-ray light. This strange star formed after two white dwarfs—remnants of stars like our sun—collided and merged. But instead of destroying each other ...

A team of researchers from Potsdam University and Kazan Federal University has found evidence of a previously unknown kind of star in nebula IRAS 00500+6713. In their paper published in the journal Astronomy & Astrophysics, ...
This burst of color shows a fascinating discovery: a galaxy cluster acting as a cosmic furnace. The cluster is heating the material within to hundreds of millions of degrees Celsius—well over 25 times hotter than the core ...

Astronomers from Australia and Taiwan report the discovery of millihertz quasi-periodic oscillations in a neutron-star low-mass X-ray binary known as 1RXS J180408.9−342058. The discovery, detailed in a paper published September ...
ESA's XMM-Newton X-ray observatory has spied hot gas sloshing around within a galaxy cluster—a never-before-seen behaviour that may be driven by turbulent merger events.
