Hubble detects helium in the atmosphere of an exoplanet for the first time

The exoplanet WASP-107b is a gas giant, orbiting a highly active K-type main sequence star. Image credit: NASA, ESA Astronomers using the NASA/ESA Hubble Space Telescope have detected helium in the atmosphere of the exoplanet WASP-107b. This is the first time this element has been detected in the atmosphere of a planet outside the Solar System. The discovery demonstrates the ability to use infrared spectra to study exoplanet extended atmospheres. The international team of astronomers, led by Jessica Spake, a PhD student at the University of Exeter in the UK,…
