PSI unveils Mercury's hidden glaciers, suggesting new astrobiological insights

Tucson AZ (SPX) Nov 18, 2023
Scientists from the Planetary Science Institute have uncovered evidence of potential salt glaciers on Mercury, opening a new frontier in astrobiology by revealing a volatile environment that might echo habitability conditions found in Earth's extreme locales. "Our finding complements other recent research showing that Pluto has nitrogen glaciers, implying that the glaciation phenomenon extends from the hottest to the coldest confines within our Solar System. These locations are of pivotal importan ... read more

Europe-Japan space mission captures images of Mercury

Paris (AFP) Oct 2, 2021
The European-Japanese BepiColombo spacecraft has sent back its first images of Mercury, the nearest planet to the Sun, the European Space Agency said Saturday. The images were obtained almost three years after the unmanned mission vessel was launched aboard an Ariane 5 Rocket. The cameras attached the BepiColombo provided black-and-white images, the ESA said in a statement. But as the spacecraft arrived on the night side of the planet, conditions were "not ideal" for taking images at its clo ... read more
