In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have identified a previously unknown supernova remnant, dubbed “Hoinga.” The finding was confirmed in archival radio data and marks the first discovery of a joint Australian-eROSITA partnership established to explore our Galaxy using multiple wavelengths, from low-frequency radio waves to…

After a Boeing 777 Rained Failed-Engine Debris on Neighborhood Below, More Planes Grounded
After a twin-engine, wide-bodied Boeing 777 took off from a Denver airport — carrying 231 passengers and 10 crew members — its right engine failed. It began dropping debris on several neighborhoods below, CNBC reports. America’s Federal Aviation Administration issued a statement saying it was “aware of reports of debris in the vicinity of the airplane’s flight path,” CNBC adds, noting…
