An active galactic nucleus in the center of ESO 253-G003, an active galaxy over 570 million light-years away in the southern constellation of Pictor, erupts...
HSC J023336-053022, a massive galaxy cluster located approximately 4 billion light-years away from Earth, is heating the material within it to hundreds...
Astronomers using ESA’s XMM-Newton and NASA’s Chandra X-ray observatories have observed a 3-million-light-year-long bridge of hot gas linking two unequal...
Professor Andrew King from the University of Leicester has shown that periodic X-ray eruptions from a galaxy called GSN 069 could result from the core...
Space-based X-ray observations of hundreds of galaxy clusters suggest that the Universe may be different depending on which way astronomers look. The study...
A bright X-ray source in a massive star cluster in the outskirts of 6dFGS gJ215022.2-055059, a barred lenticular galaxy located about 806 million light-years...
Using data from the European Photon Imaging Camera (EPIC) onboard ESA’s XMM-Newton X-ray observatory, astronomers have detected for the first time a...
As material spirals towards a black hole, it is heated up and emits X-rays that, in turn, echo and reverberate as they interact with nearby gas. These...
Using data from NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton, the Giant Metrewave Radio Telescope, and the Apache Point Observatory, astronomers...
Astronomers using data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton spacecraft have found evidence that an invisible force called dark...
University of Leicester’s Professor Ken Pounds and co-authors report the detection of matter falling into a black hole at 30% of the speed of light.
This...
Ordinary (baryonic) matter make up all physical objects in existence, from stars to the cores of black holes. But until now, scientists had only been able...
Astronomers studying RZ Piscium, a variable Sun-like star located approximately 555 light-years away in the constellation Pisces, have found evidence suggesting...
X-rays emitted by a Sun-like star may provide valuable information about whether its planetary system will be hospitable to life, a new study suggests....
