Comets that have hit Earth have been a mixed bag. Early in Earth's history, during the solar system's chaotic beginning, they ...

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 ...

With the exception of Pluto, planets in our solar system are classified as either terrestrial (Earth-like) or Jovian (Jupiter-like) planets. Terrestrial planets include Mercury, Venus, Earth ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was ...

Swirling around that fireball were particles that gathered into spherical clumps, whose gravitational fields attracted smaller clumps, and so on, eventually creating the four terrestrial planets ...

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 ...

My research focuses on terrestrial planets and moons. I am particularly interested in polar ice caps and their interactions with planetary atmospheres. For example, the polar deposits of Mars record ...

Most terrestrial planets have atmospheres, but the conditions on their surfaces would not allow humans to survive there. Venus is the hottest planet in our solar system (despite being further from ...
