Astronomers using two Maunakea Observatories -- Subaru Telescope and W. M. Keck Observatory -- combined with the power of machine learning, have discovered a nearby galaxy that has broken the record for having the lowest level of oxygen ever seen....

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...

Some areas on Mars are covered in huge valleys that many think were carved by rivers in the planet's warmer past, but they may have actually been formed by glaciers, pointing to a chilly early Mars

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.

The first astronauts to launch to the International Space Station on a commercial spacecraft have now returned, splashing down into the sea off the coast of Florida
