An international team of astronomers reports the discovery of a new cataclysmic variable. The newfound system, designated SRGeJ041130.3+685350 (or SRGeJ0411 for short), has an orbital period of about 100 minutes and may contain ...
Using the Tsinghua University–Ma Huateng Telescopes for Survey (TMTS), an international team of astronomers has discovered a new binary known as TMTS J052610.43+593445.1. The newfound system is an ultrashort-orbital-period ...
The solar wings that will power ESA's Hera asteroid mission for planetary defense as it ventures out to meet the Dimorphos asteroid have been cleared for flight. As part of its current test campaign at ESA's ESTEC Test Center ...
