The Mars Camera, CaSSIS (Colour and Stereo Surface Imaging System), on ESA’s ExoMars Trace Gas Orbiter captured its first high-resolution images of the Red Planet last week. Developed by a team at the University of Bern in Switzerland, CaSSIS is providing spectacular views, including the Hebes Chasma region at a resolution of 2.8 metres per pixel.
Based on computer simulations, astrophysicists at the University of Bern conclude that comet 67P/Churyumov–Gerasimenko did not obtain its duck-like form during the formation of our solar system 4.5 billion years ago. Although it does contain primordial material, they are able to show that the comet in its present form is hardly more than a billion years old.
Astrophysicists at the University of Bern conducting computer simulations of the formation of planets orbiting in the habitable zone of low-mass stars, such as the red dwarf Proxima Centauri, show that these planets are most likely to be roughly the size of the Earth and to contain large amounts of water.
ESA’s Rosetta spacecraft has made the first in situ detection of oxygen molecules outgassing from Comet 67P/Churyumov-Gerasimenko, a surprising observation that suggests they were incorporated into the comet during its formation. This may have implications for our understanding of the chemistry involved in the formation of the solar system some 4.6 billion years ago.
