Helium signal reveals the comet-like tail of exoplanet WASP-69b for the first time

06/12/2018
A new study, led by scientists from the Instituto de Astrofísica de Canarias (IAC), reveals that the giant exoplanet WASP-69b carries a comet-like tail made up of helium particles escaping from its gravitational field propelled by the ultraviolet radiation of its star. The results of this work, in which IAC researchers Lisa Nortmann and Enric Pallé participate, are published today in the journal Science. >> Read more
