This artist’s illustration represents the possible interior dynamics of the super-Earth exoplanet LHS 3844b. The planet’s interior properties and the strong stellar irradiation might lead…
An illustration showing how a combination of static high-pressure synthesis techniques and dynamic methods enabled the researchers to probe the magnesium silicate bridgmanite, believed to…
Nearly 42,000 years ago, when Earth’s magnetic fields reversed, this triggered major environmental changes, extinction events, and long-term changes in human behavior, a new study…
