An international team has made a significant breakthrough in understanding the tectonic evolution of terrestrial planets.

Scientists have long been intrigued by the surfaces of terrestrial bodies other than Earth that reveal deep similarities beneath their superficially differing volcanic and tectonic histories. A team ...

To reproduce the orbits and masses of the terrestrial planets (analogs) of the solar system, most studies scrutinize simulations for success as a batch. However, there is insufficient discussion in ...

Late-stage planetary collisions reshaped Earth and its neighboring planets, delivering water, altering their atmospheres, and influencing their tectonics. New findings suggest these violent impacts ...

A long-ago reshuffling of the giant planets in our solar system may have been instrumental in giving Earth its moon. For decades, planetary scientists have hypothesized that Jupiter, Saturn, Uranus ...

Best chance of finding liquid water, and even life on other planets, is to look for the absence of carbon dioxide in their atmospheres. Scientists at MIT, the University of Birmingham, and elsewhere ...

Theia' is a long-vanished world, a planet-sized body thought to have smashed into the early Earth and that helped to form the ...

The European Space Agency (ESA) spacecraft now has 24 of its 26 cameras installed, which once launched will be used to hunt for terrestrial planets. The European Space Agency (ESA) is two dozen steps ...
