Using the Hubble Space Telescope (HST) and the Chandra X-ray Observatory, astronomers have taken a closer look at a short-period high-mass X-ray binary known as CXOU J121538.2+361921. Results of the observational campaign, ...
Using the Spectrum–RG (SRG) spacecraft and two ground-based telescopes, Russian astronomers have observed X-ray sources in the eastern Galactic sky. The observational campaign resulted in the detection of 14 new active ...
Experts created two new visual and auditory experiences to explore the complexity and beauty of a compact galaxy group known as Stephan's Quintet. The guided three-dimensional visualization surveys the galaxies—their structures, ...
