Candid cosmos: eROSITA cameras set benchmark for astronomical imaging

SPIE International Society for Optics and Photonics
Recently, the eROSITA (extended Roentgen Survey with an Imaging Telescope Array) x-ray telescope, an instrument developed by a team of scientists at Max-Planck-Institut für Extraterrestrische Physik (MPE), has gained attention among astronomers. The instrument performs an all-sky survey in the x-ray energy band of 0.2-8 kilo electron volts aboard the Spectrum-Roentgen-Gamma (SRG) satellite that was launched in 2019 from the Baikonur cosmodrome in Kazakhstan.
“The eROSITA has been designed to study the large-scale structure of the universe and test cosmological models, including dark energy, by detecting galaxy clusters with redshifts greater than 1, corresponding to a cosmological expansion faster than the speed of light,” said Dr. Norbert Meidinger from MPE, a part of the team that developed the instrument. “We expect eROSITA to revolutionize our understanding of the evolution of supermassive black holes.” The d ....

Bad Astronomy | Supernova debris Hoinga found in X-rays

The technical name of this supernova remnant is SNR G249.5+24.5, but the astronomers who discovered it dubbed it Hoinga, after the medieval name of the first author s hometown, Bad Hönningen am Rhein.

They found it in observations taken by a mission called eROSITA (extended Röntgen Survey Imaging Telescope Array;
Röntgen is the German word for X-rays, after their discoverer). This is a space-based X-ray observatory on board a German-Russian spacecraft called Spectrum-Roentgen-Gamma, which orbits the Sun about 1.5 million kilometers from the Earth in a spot called the L2 point, a volume of space where a spacecraft can remain semi-stable without too much effort. ....

Valentine Island in northern Western Australia is a swirling mix of blues and reddish browns, as seen from space by the Copernicus Sentinel-2 mission. The mission, which is made up of two satellites, imaged the tiny island for Valentine s Day. Valentine Island is just about 1 mile (1.60 kilometers) long and 0.15 miles (250 meters) wide and can be found in the King Sound, a large gulf that has one of the highest tides in all of Australia.

The European Space Agency s Copernicus Sentinel-2 mission snapped this chilly photo of New York City on Feb. 4, 2021 showing the city blanketed in snow. This recent snow storm was classified as major and affected a majority of the Northeast United States, with New York declaring a state of emergency for both the immense snowfall and blistering winds. Copernicus Sentinel-2 is an Earth-observing mission made up of two satellites: Sentinel-2A and Sentinel-2B. The pair monitor and image our planet, orbiting it from space.
