A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience....

One of the proposed scenarios for the origin of life is the primordial RNA world, which considers that RNA molecules were likely responsible for the storage of genetic information and the catalysis of biochemical reactions in primitive cells, before the...

Using the high-angular resolution observations from ESO’s Very Large Telescope (VLT), astronomers have determined the 3D shape, diameter and density of the asteroid (31) Euphrosyne and the diameter of its moon. Euphrosyne, one of the biggest objects in the Solar Systrem’s main asteroid belt, was discovered by James Ferguson on September 1, 1854, the first [...]

Ice plays a critical role in keeping Earth’s climate cool, but our rapidly warming world is taking its toll and ice is in general decline. For more than 10 years, ESA’s CryoSat has been returning critical information on how the height of our fragile ice fields is changing. Nevertheless, to gain even better insight, ESA has spent the last two weeks nudging CryoSat into a higher orbit to synchronise it with NASA’s ICESat-2 so that scientists can benefit from simultaneous measurements from different space sensors.
