Astronomers of the SPECULOOS Liege team are currently at the European Southern Observatory of Paranal (Chile) to commission the first telescope of the project, which is funded by the European Research Council. This telescope, named Europa, is the first of the four telescopes that will comprise the SPECULOOS Southern Observatory which will soon scout the southern skies in search for TRAPPIST-1-like planetary systems around a large sample of nearby ultracool dwarf stars.
ULg astronomers discovered seven telluric planets around the star TRAPPIST-1. “The TRAPPIST-1 system is the largest treasure of terrestrial planets ever detected around a single star.” This discovery, published this week in the journal Nature, revives the quest for life in the Universe.
Laetitia Delrez used information gathered over a period of four years about discoveries and characterizations of hot Jupiters to complete her thesis. She uncovered a wealth of information about these gas giants that orbit very close to their star.
The documentary "In Search of Lives in the Universe", broadcast on France 5 television presents - at the end - the discovery, thanks to the TRAPPIST telescopes, of the Trappist-1 planetary system.
Si la météo le permet, n'hésitez pas à mettre le nez dehors cette nuit car la lune sera jusqu'à 14% plus grosse et 30% plus lumineuse. Un phénomène assez rare puisqu'il n'a plus été observé depuis 70 ans. Mais à quoi est-il d&ucric; ? Voici les explications.
