2019年5月30日 · A diffuse glow permeates the X-ray sky even far from bright sources. This image of the whole sky shows 22 months of X-ray data recorded by NASA’s Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station during its nighttime slews between targets.

2020年7月8日 · A new X-ray map of the entire sky, using data from the eROSITA telescope’s first full scan, looks deeper into space than any other of its kind.

X-ray astronomy is an observational branch of astronomy which deals with the study of X-ray observation and detection from astronomical objects. X-radiation is absorbed by the Earth's atmosphere, so instruments to detect X-rays must be taken to high altitude by balloons, sounding rockets, and satellites.

2020年7月9日 · Wish you had X-ray vision? An extraordinary new map showcases the universe in striking, X-ray radiation. Scientists created this stunning X-ray map of the universe using eROSITA (Extended...

2020年6月19日 · For months, the eROSITA telescope aboard the Spektr-RG space observatory has been scanning the entire sky, collecting observations for the deepest all-sky survey in X-ray wavelengths. Now, all those data have been compiled into a map containing over 1 million bright X-ray objects - approximately doubling the number of such objects from the ...

2024年2月11日 · The eROSITA first data release is a rich, "multi-layered" look at the sky at several X-ray energies. Each energy level tells astronomers something about the objects and events emitting the X-rays. And, for each set of images and …

2019年6月3日 · Astronomers used NASA's Chandra X-ray Observatory to study the supernova remnant Cassiopeia A and discovered titanium, shown in light blue, blasting out of it. The colors represent other elements...

This X-ray image of the entire sky was constructed with Skyview, using data from the first High Energy Astronomy Observatory (HEAO 1), and plotted in a coordinate system centered on the galactic center with the north galactic pole at the top.

2020年6月19日 · After six months of uninterrupted scanning of the whole sky, eROSITA, the new powerful X-ray telescope onboard the Russian-German Spektrum-Roentgen-Gamma (SRG) space mission, has delivered a new map of the hot and energetic sky.
