Using the James Webb Space Telescope (JWST), the Hubble Space Telescope (HST) and the Gemini Observatory, European astronomers have observed a nearby cold brown dwarf known as WISE 1738. Results of the observational campaign, ...
Recent observations of Jupiter's powerful magnetic field by NASA's Juno spacecraft have uncovered a never-before-documented variety of plasma waves that seem to defy our current understanding of planetary magnetospheres.
Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a nearby star. The newfound alien world, designated TOI-2431 b, is comparable in size to Earth ...
Using a cutting-edge magnetic wave detection technique, a new study in Nature Communications has identified lithium in Mercury's exosphere for the first time.
