First study with CHEOPS data describes one of the most extreme planets in the universe
CHEOPS keeps its promise: Observations with the space telescope reveal details of the exoplanet WASP-189b – one of the most extreme planets known. 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. Eight months after the […]

Art and space
#InspiredByOtherWorlds, an “Art contest” for all launched by Europlanet This year and for the first time, the European congress dedicated to exoplanets (which took place in Geneva last year) will take place online, as a consequence of the health crisis. On this occasion the Europlanet society (#EPSC2020) invites schools and space enthusiasts of all ages […]
Continue ReadingPhD position – study the atmospheres of exoplanets
An SNSF funded PhD position (4 years duration) is available to study the atmospheres of exoplanets under the guidance of Dr. Graham K.H. Lee at the Center for Space and Habitability (CSH), University of Bern in Switzerland. With the onset of launch of JWST, astronomers are set to revolutionise our understanding of exoplanet atmospheres. Motivated […]

Three years of HARPS-N solar data to help detecting “Earth 2.0”
In order to better characterize the noise introduced by stars when searching for new exoplanets, five years ago the HARPS-N spectrometer, mounted on the Telescopio Nationale Galileo, was equipped with a small dedicated solar telescope. The data acquired by this telescope during the first three years of observations – collected every five minutes on all […]

Stars with planets show no special fingerprint
With the participation of the NCCR PlanetS, an international team of scientists has determined the chemical composition of 84 stars with great precision. Contrary to popular scientific theory, their results show that there seem to be no clear chemical differences between stars with and without planets. For 25 years it has been known planets orbit […]

Applications are invited for a postdoctoral position within the Geneva exoplanet team to work on optimisation of radial velocity extraction in the context of the BLUVES project. The goal of BLUVES is to develop a reliable laser frequency comb for blue part of visible high-precision spectrographs. The goal is to explore and compare all the […]

When in doubt, aim high
Veerle Sterken had been away from a paid job in cosmic dust science for three years. Then she convinced the European Research Council (ERC) to fund her project on interstellar dust. That kick-started her “second career” in astrophysics and led to her project being welcomed into PlanetS by the board. “I will send out my […]

Three Earth-like planets identified in two planetary systems
PlanetS astronomers associated with an international team have estimated the density of the planets in two planetary systems. Discovered by the Kepler satellite, K2-32 and K2-233 are planetary systems with 4 and 3 planets respectively. The diameters of the planets have been measured by Kepler thanks to the transit method which uses the obscuration of […]
