Astronomers from the Astronomical Observatory of Padova, Italy, and elsewhere have conducted observations of 25 stars as part of the COPAINS Pilot Survey. As a result, they detected four new brown dwarfs that received designations ...
NASA's Hubble Space Telescope has uncovered a witness at the scene of a star's explosive death: a companion star previously hidden in the glare of its partner's supernova. The discovery is a first for a particular type of ...

Astronomers from Jena Observatory in Germany and elsewhere have performed follow-up observations of a nearby binary star system known as Gamma Cephei. Results of the observational campaign, published March 8 on arXiv.org, ...
In 2020 a team led by European Southern Observatory (ESO) astronomers reported the closest black hole to Earth, located just 1,000 light-years away in the HR 6819 system. But the results of their study were contested by other ...

Astronomers from Louisiana State University (LSU) and College of Charleston have performed photometric observations of a recurrent nova known as V2487 Oph. The observational campaign identified superflares on this source ...
Signs of a planet transiting a star outside of the Milky Way galaxy may have been detected for the first time. This intriguing result, using NASA's Chandra X-ray Observatory, opens up a new window to search for exoplanets ...
