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 |
Source of electron acceleration and X-ray aurora of Mercury Kanazawa, Japan (SPX) Oct 11, 2023 Since Mercury is the closest planet to the Sun among the solar system planets, it is strongly influenced by the solar wind, a high-speed (several hundred km/s) stream of plasma blowing from the Sun. ... more Tucson AZ (SPX) Sep 15, 2023 A new study maps the infall of protons and electrons from the solar wind to geographical location on the surface of Mercury, giving scientists new insight into how interactions with the Sun alters t ... more London, UK (SPX) Jul 19, 2023 BepiColombo, the joint European Space Agency (ESA) and Japanese Aerospace Exploration Agency (JAXA) mission, has revealed how electrons raining down onto the surface of Mercury can trigger high-ener ... more Tempe AZ (SPX) Jul 11, 2023 The origin of Mercury, the closest planet to the sun, is mysterious in many ways. It has a metallic core, like Earth, but its core makes up a much larger fraction of its volume - 85% compared to 15% ... more |

Solar Wind a Major Driver of Atmospheric Sodium at Mercury Washington DC (SPX) May 31, 2022 No object in the solar system experiences the Sun's solar wind more powerfully than Mercury. The planet's magnetic field deflects the Sun's stream of electrically charged particles at a distance of ... more Leiden, Netherlands (SPX) Apr 22, 2022 Mercury harbors water ice in the shadows of the steepest craters around its poles. But it is unclear how those water molecules ended up on Mercury. Now a new simulation shows that incoming minor bod ... more Fairbanks AS (SPX) Apr 01, 2022 An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. The research by scientists in the United Stat ... more Columbia MD (SPX) Mar 17, 2022 Despite being the closest planet to the Sun, some craters on Mercury's poles contain ice. The deposits, which were first detected in the early 1990s, were thought to be thick layers of nearly pure w ... more Paris (ESA) Oct 05, 2021 The ESA/JAXA BepiColombo mission has captured its first views of its destination planet Mercury as it swooped past in a close gravity assist flyby last night.

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 Paris (ESA) Oct 04, 2021 The joint European-Japanese BepiColombo mission captured this view of Mercury on 1 October 2021 as the spacecraft flew past the planet for a gravity assist manoeuvre. The image was taken at 23 ... more |
