CHEOPS finds unique planetary system

CHEOPS finds unique planetary system

The CHEOPS space telescope detects six planets orbiting the star TOI-178. Five of the planets are in a harmonic rhythm despite very different compositions – a novelty. CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the aegis of the University of Bern in collaboration with the University of Geneva. […]

The importance of theory in exoplanetary science

The importance of theory in exoplanetary science

Scientists at the University of Zurich associated with the National Center of Competence in Research PlanetS reveal considerable uncertainties in the theoretical understanding of giant gas planets. This emphasizes the importance of further developing theoretical aspects of exoplanetary characterization. Planets that orbit other stars are very far away. Even the ones close enough for instruments […]

Dear Reader, One year in space, more than 5300 Earth orbits completed corresponding to more than 236 million kilometers travelled, and over 439’000 superb images downlinked. All things considered, CHEOPS had a  very good year in space  compared to what happened to us on the ground. Of course, we had our moments of stress before […]

One-year launch anniversary of CHEOPS

One-year launch anniversary of CHEOPS

In its first year in orbit, the CHEOPS space telescope has already revealed details of one of the most extreme exoplanets and showed its maneuverability by evading space debris. CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the aegis of the University of Bern in collaboration with the University […]

New insights into Earth’s primeval atmosphere

New insights into Earth’s primeval atmosphere

A team of international scientists, led by the ETH Zurich and the National Centre of Competence in Research (NCCR) PlanetS, has gained new insights into Earth’s atmosphere of 4.5 billion years ago. Their results have implications for the possible origins of life on Earth. Four and a half billion years ago, Earth would have been […]

How giant planets turn gas to metal

How giant planets turn gas to metal

New theoretical insights and space mission data have changed our perception of the Solar system’s largest planets. Scientists from the University of Zurich, involved in the National Centre of Competence in Research PlanetS, have reviewed our current state of knowledge. Earth is a terrestrial planet. It consists of a mostly solid rocky crust and molten […]

How water explains missing planets

How water explains missing planets

Space exploration telescopes have revealed that planets between the size of 1.3 and 2.4 Earth radii seem to be c comparatively rare. Scientists under the lead of the International Space Science Institute and the National Centre of Competence PlanetS have found a remarkably simple explanation. Since 1995, scientists have found over 4000 planets outside the […]

Two planets around a red dwarf

Two planets around a red dwarf

The “SAINT-EX” Observatory, led by scientists from the National Centre of Competence in Research NCCR PlanetS of the University of Bern and the University of Geneva, has detected two exoplanets orbiting the star TOI-1266. The Mexico-based telescope thus demonstrates its high precision and takes an important step in the quest of finding potentially habitable worlds. […]
