An international team of astronomers have performed photometric and spectroscopic observations of a Type Ibn supernova, known as SN 2023fyq. Results of the observations campaign, published May 7 on the pre-print server arXiv, ...
Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising ...

An international team of astronomers reports the detection of a rare eclipsing Be/X-ray binary system as part of the Swift Small Magellanic Cloud (SMC) Survey (S-CUBED). The finding was detailed in a research paper published ...
Do exoplanets have exomoons? It would be extraordinary if they didn't, but as with all things, we don't know until we know. Astronomers thought they may have found exomoons several years ago around two exoplanets: Kepler-1625b ...
