Stronger links between researchers who work on Earth’s and other planets’ atmospheres, and between the experimental, ...

Tests on olivine hint that water-rich exoplanets could generate H2O internally, possibly explaining ocean worlds and even some of Earth’s early water.

New experiments show young rocky planets can generate water naturally when molten surfaces react with hydrogen in their early atmospheres.

Space scientists look back on 30 years of exoplanet discoveries — from rows of massive ‘super-Earths‘ to worlds with perfectly synchronized orbits. It was also the start of a whirlwind of discovery.
