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. The star is about 200 light-years from Earth. Using spectroscopy, scientists were able to find helium in the escaping atmosphere of the planet -- the first detection of this element in the atmosphere of an exoplanet. Credit: ESA/Hubble, NASA, M.

Astronomers using Hubble 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...
