It’s a great pleasure to welcome Helena Kühnle to our research group as a new doctoral student!

October 25th, 2023 our METIS Cryostat integration facility was opened in Buchs/ZH.

With the help of the James Webb Space Telescope, a team of researchers including members from the Institute for Particle Physics and Astrophysics at ETH Zurich measured ammonia in the atmosphere of a cold brown dwarf, showing that the isotopic abundance of ammonia can be used to study how giant gas planets form.
