An international team of astronomers has detected a new ultra-hot Jupiter extrasolar planet using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien world is nearly two times larger than Jupiter and has ...
Superflares, extreme radiation bursts from stars, have been suspected of causing lasting damage to the atmospheres and thus habitability of exoplanets. A newly published study found evidence that they only pose a limited ...
