An exoplanet inflated like a balloon

sciencedaily.com – Although helium is a rare element on Earth, it is ubiquitous in the universe. It is, after hydrogen, the main component of stars and gaseous giant planets. Despite its abundance, helium was only detected recently in the atmosphere of a gaseous giant by an international team. The team has observed for the first time how this gas escapes from the overheated atmosphere of an exoplanet, literally inflated with helium.
