Earth could have lost anywhere between ten and 60 per cent of its atmosphere in the collision that is thought to have formed the Moon. New research led by Durham University, UK, shows how the extent ...

Mercury is tiny, barely bigger than the Moon. Its metallic core makes up 70% of the planet’s mass, vastly exceeding Earth’s ...

A study published in the journal Nature Astronomy challenges traditional explanations about the origin of the innermost planet in the Solar System and proposes a more likely scenario. The collision ...

Damanveer Singh Grewal suggests that planetesimals in the early solar system emerged from a succession of high-energy ...

New simulations suggest that Mercury's formation could be the result of a rare collision between two celestial bodies of similar mass.

TUCSON, Ariz. — How did Pluto end up with its largest moon, Charon? Like many entanglements, it started with a kiss. New ...

Our solar system is a smashing success. A new study suggests that from its earliest period—even before the last of its ...

Pluto and Charon’s meet-cute may have started with a kiss. New computer simulations of the dwarf planet and its largest moon suggest that the pair got together in a “kiss-and-capture” collision, where ...

Could a passing star be on a collision course with our solar system and, eventually, Earth? It’s difficult to know if such an outcome is likely. Recently, researchers have found the Milky Way likely ...

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 ...
