Telltale greenhouse gases could signal alien activity
Known for their detrimental effect on Earth, greenhouse gases could be beneficial for alien civilizations afar to terraform their worlds, and an opportunity for us to spot them. An international team of scientists including Dr. Daniel Angerhausen from ETH Zurich and member of the National Centre of Competence (NCCR) PlanetS, calculated that current technology would […]

ANDES, the spectrograph in a quest for life in the Universe
The European Southern Observatory (ESO) is endorsing a new spectrograph for its future giant telescope. Switzerland is contributing thanks to its expertise in exoplanets and in high-precision instruments. ESO has started the design and construction of the ArmazoNes high Dispersion Echelle Spectrograph (ANDES) with an international consortium involving the University of Geneva and the University […]

Discovery of a planet around an ultra-cool star
An international team of astronomers – including members of the NCCR PlanetS, the University of Geneva (UNIGE) and the University of Bern (UNIBE) – has discovered, for only the second time, an Earth-sized exoplanet (SPECULOOS-3 b) around an ultra-cool Red Dwarf star. Red dwarfs account for 70% of the stars in our galaxy. The small […]

Hints of a possible atmosphere around a rocky exoplanet
Researchers using NASA/ESA/CSA James Webb Space Telescope may have detected an atmosphere surrounding 55 Cancri e, a rocky exoplanet 41 light-years from Earth. This is the best evidence to date for a rocky planet atmosphere outside our solar system. Brice-Olivier Demory, Professor of Astrophysics at the University of Bern and member of the the National […]

How Pluto got its heart
The mystery of how Pluto got a giant heart-shaped feature on its surface has finally been solved by an international team of astrophysicists led by the University of Bern and members of the National Center of Competence in Research (NCCR) PlanetS. The team is the first to successfully reproduce the unusual shape with numerical simulations, […]

CHEOPS detects a ‘‘rainbow’’ on an exoplanet
New observations from the space telescope point to the existence of a «glory» in the atmosphere of WASP-76b, a luminous phenomenon like a rainbow. The CHEOPS space telescope, whose scientific operations centre is based at the University of Geneva (UNIGE – co-leading house of the NCCR PlanetS), is providing new information on the mysterious exoplanet […]
