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 ...

A new SwRI-led paper highlights the scientific progress made in understanding the evolution of terrestrial planets, including the effects of late large impacts on pre-existing modes of tectonics. For ...

Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.

An international team has made a significant breakthrough in understanding the tectonic evolution of terrestrial planets. Using advanced numerical models, the team systematically classified for the ...

Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers’ best chance of finding liquid water, and even life on other planets, is to look for the absence, rather than the ...

Astronomers have discovered the youngest known Earth-sized planet circling a nearby Sun-like star. At just 400 million years old, the newfound world, named HD 63433 d, is more than 10 times younger ...

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 ...
