Astronomers have recently observed a low-mass X-ray binary known as IGR J17407−2808 with NuSTAR and XMM-Newton space telescopes. In result, they detected several fast X-ray flares from this source. The finding was reported ...
Astronomers using data from NASA's Chandra X-ray Observatory and other telescopes have identified a new threat to life on planets like Earth: a phase during which intense X-rays from exploded stars can affect planets over ...

Using AstroSat and NuSTAR space telescopes, astronomers have observed an X-ray binary known as XTE J1739−285 during its recent period of bursting activity. Results of the observational campaign, published March 23 on the ...
Using NASA's Chandra spacecraft, an international team of astronomers has performed X-ray observations of the Cigar Galaxy. Results of the observational campaign, presented March 16 on the pre-print repository arXiv, deliver ...
Using the Imaging X-ray Polarimetry Explorer (IXPE), an international team of astronomers has conducted X-ray polarimetric observations of an accreting X-ray pulsar known as Vela X-1. Results of the observational campaign, ...
For the first time, researchers have recorded live and in atomic detail what happens to the material in an asteroid impact. The team of Falko Langenhorst from the University of Jena and Hanns-Peter Liermann from DESY simulated ...

Using various space telescopes, astronomers have performed X-ray observations of a radio pulsar known as PSR J1420−6048. Results of the observational campaign, published January 27 on the arXiv pre-print server, shed more ...
For the first time since it was proposed more than 80 years ago, scientists from Nanyang Technological University, Singapore (NTU Singapore) have demonstrated the phenomenon of "quantum recoil," which describes how the particle ...
