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 details of

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.

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.

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.
