Hubble detects helium in the atmosphere of an exoplanet for the first time
https://www.spacetelescope.org/news/heic1809/?lang

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.
