Examining the atmospheres and climate of exoplanets
After being able to measure the masses and the diameters of exoplanets, using the information to deduce what materials they have formed from, astronomers now seek to detect the chemical composition of their atmospheres if they possess one. For several years, atmosphere detection announcements have been in the news before being questioned and recently proven. […]

A new teacher at PlanetS
Emeline Bolmont has just been appointed Assistant Professor in the Department of Astronomy at the University of Geneva, a position funded by PlanetS. Originally from Toul near Nancy in north-eastern France, the new professor was introduced to astronomy at a very early age by her parents who occasionally went to observe the sky on a […]

Neural networks predict planet mass
To find out how planets form, astrophysicists run complicated and time consuming computer calculations. Members of the NCCR PlanetS in Bern have now developed a totally novel approach to speed up this process dramatically. They use deep learning based on artificial neural networks, a method that is well known in image recognition. Planets grow in […]

Current highlights of PlanetS research
Astronomers have discovered a large number of rocky planets outside our solar system. Among them there are many exotic objects which we do not know in our solar system: Super-Earths, some of them even rich in gems, or water worlds with a global ice layer on the ocean floor. But what does it take to […]

Astronomy Outreach Like A Rocket
For the fifth time already, the public and free science slam “Astronomy on Tap” took place at “ONO Kulturlokal” in Bern. On the occasion of the “United Nations International Day of Women and Girls in Science” and the “IAU100 Women & Girls in Astronomy Day” on 11 February 2019, four female space scientists spoke about […]

Insights from the moon to the exoplanets
In the anniversary year of the moon landing of Apollo 11 there are exciting things to discover. The University of Berne will be celebrating a science festival together with the public from 27 to 30 June 2019. The Swiss National Library in Berne is showing a transport container for the Apollo solar wind experiment. And […]

A sister of the Earth in a nearby system
Barely three times larger than the Earth, this new planet is the third closest to our solar system ever discovered. An international team of astronomers, including researchers from the University of Geneva and PlanetS, has discovered the third closest exoplanet to our solar system. This detection was obtained thanks to the SOPHIE spectrograph, developed in […]

The Star and Planet Formation Research Group at the Institute for Particle Physics and Astrophysics at ETH Zurich invites applications for a new post-doctoral fellowship to work with Dr. Sascha Quanz on the characterization of (small) extra-solar planets. We are looking for a postdoc with expertise in atmospheres / atmospheric retrieval techniques and/or habitability research […]

Better to dry a rocky planet before use
Earth’s solid surface and clement climate may be in part due to a massive star in the birth environment of the Sun. Without its radioactive elements injected into the early solar system, our home planet could be a hostile ocean world covered in global ice sheets. This is the result of computer simulations of planet […]

The exoplanet team of the University of Geneva has an opening for four postdoctoral researchers to work on detection and characterization of exoplanets through high-precision radial velocity measurements. Focusing on the low-mass range of exoplanets and using the high-precision spectrographs CORALIE, HARPS, HARPS-N, ESPRESSO, SPIROU, and NIRPS, our team is strongly involved in blind radial velocity surveys as well as in the follow-up of transiting candidates from […]
