A U.S. scientist searching for a civilization across 7 Earth clones circling the red dwarf star TRAPPIST-1 says its own alien astronomers could also be scanning Earth.

These rocky bits eventually coalesced to form the terrestrial planets. However ... This first-order model of planetary growth in the solar nebula is mainly driven by temperature and density ...

We have developed a state-of-the-art atmospheric climate-biogeochemical model for terrestrial planets (1D-TERRA) with photochemistry and unique air-shower physics. We are international leaders in ...

Our research interests have been primarily in understanding the physical processes that control the evolution of terrestrial planets (Earth, Moon, Mars, ...). Modern space exploration has provided ...

A new climate modeling study presents a new scenario of how climate and life on our planet would change in response to a potential future strike of a medium-sized (~500 m) asteroid.

The interval of bombardment is thought to have shaped the terrestrial planets and moons, their atmospheres and possibly even the onset of life. In this web focus, we present research papers ...

These rocky bits eventually coalesced to form the terrestrial planets. However, at a distance of around 4 ... of the gas and ice giants in the outer solar system. This first-order model of planetary ...
