Scientists evaluated how the atomic structure of magnesium germanate changes under extremely high pressures. They discovered that the mineral adopted the structure of a compound called thorium phosphide. This, they think, could be an important component of the deep interiors of large, rocky extrasolar planets.

The extremely salty, very cold, and almost oxygen-free environment under the permafrost of Lost Hammer Spring in Canada's High Arctic is the one that most closely resembles certain areas on Mars. So, if you want to learn more about the kinds of life forms that could once have existed - or may still exist - on Mars, this is a good place to look.

Astronomers have discovered one of the youngest known neutron stars - possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar's powerful magnetic field emerged from behind a thick shell of debris from the explosion.

Astronomers have found only the second example of a highly active, repeating Fast Radio Burst (FRB) with a compact source of weaker but persistent radio emission between bursts. The discovery raises new questions about the nature of these mysterious objects and also about their usefulness as tools for studying the nature of intergalactic space.
