Polish astronomers have detected a new ultracompact X-ray binary as part of the Optical Gravitational Lensing Experiment (OGLE). The newly found binary, designated OGLE-UCXB-01, is an unusual periodic variable object with ...
Astronomers have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star. If this planet were somehow placed into our own solar system, it would swing from within our asteroid ...
