1 year of operations : Meet the CHEOPS science operations team
To ensure the smooth running of the CHEOPS mission once the satellite is in orbit, operations have been split in two parts : Science Operations in Switzerland with the Scientific Operations Centre (SOC) in Geneva and the Instrument Team in Bern, and the Mission Operations Centre (MOC) in Torrejón, Spain, which is in charge of communication […]

Celebrating two decades of SPHERE challenges and achievements
Reaching new heights with 100 consortium publications including the early exoplanet demographics release. The SPHERE (Spectro-Polarimetric High-contrast Exo-planet REsearch) planet imager(1), currently installed and operating at the ESO Very Large Telescope in Chile, aims at imaging and characterizing giant exoplanets and planet-forming disks around stars close to the Sun. This project represents an incredible scientific, […]

NIRPS spectrograph delivers its first images in Quebec
The NIRPS spectrograph optical components has been successfully integrated and aligned into its cryogenic vacuum chamber and delivered its first images in August in the Université Laval’s laboratory. This is an important step before the instrument being installed on the 3.6-m ESO telescope in La Silla, Chile and joining the well-known high-resolution spectrograph HARPS to […]

First picture of a planetary system around a Sun-like star
Out of the 4300 exoplanets that have been detected to date, only a few dozen have been detected thanks to direct imaging, i.e. we have been able to physically see a planet around its star in an image. Indeed the star is so bright compared to the planets that it is necessary to use indirect […]

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 […]

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 […]

ESPRESSO confirms the existence of an exo-Earth 4 light-years away
An international team of experts, including researchers from the NCCR PlanetS, has confirmed the existence of the Proxima b extrasolar planet using measurements from the Swiss-built ESPRESSO spectrograph. The existence of a planet the size of Earth around the closest star in the solar system, Proxima Centauri, has been confirmed by an international team of scientists […]
