The final flyby of the northern pole of Saturn by the Cassini spacecraft was the last opportunity to take images of the aurorae before the end of the mission. Unexpectedly, the ultimate image is very attractive, displaying an explosion of polar lights, all connected to different phenomena in the magnetosphere of Saturn. A bright polar [...]
On September 15, the Cassini spacecraft is going to plunge into the atmosphere of Saturn where it will be vaporized, marking the end of more than 13 years of exploration of Saturn and its environment.

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. This artist’s impression shows the view from the surface of one [...]

The foreground of this image shows ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile. The rich stellar backdrop to the picture includes the bright star Alpha Centauri, the closest stellar system to Earth. In late 2016 ESO signed an agreement with the Breakthrough Initiatives to adapt the VLT instrumentation to conduct [...]
LIEGE, December 19, 2016 - For the first time, geologists from the University of Liège have been able to determine the nature of the minerals present on the surface of Mercury - one of the four telluric planets in our solar system. Their study, published this week in the journal Nature Geoscience, is based on [...]
Measuring a billion stars ... for a billion euros! This is the bet of Gaia, the mission of surveying and 3D mapping that covers several percent of our galaxy. Launched in December 2013, the Gaia satellite has since ceased surveying space. On September 14th, the 450 or so scientists who interpret the data he transmitted [...]
Following an in-depth analysis over the course of ten years – from 2004 to 2014 – of data from the SPICAM instrument placed on board European orbiter Mars Express, Lauriane Soret, researcher at the University of Liège’s laboratory of atmospheric and planetary physics, and her colleagues have identified aurorae in Mars’ atmosphere. This rare phenomenon [...]
