Recent scientific modeling has proposed a fascinating theory about how Pluto captured its largest moon, Charon. The theory ...

Scientists have shown how the freezing of a ‘slushy’ ocean of magma may be responsible for the composition of the Moon’s crust. The scientists, from the University of Cambridge and the Ecole normale ...

It is a striking paradox: while the overwhelming majority of lunar rocks that have been dated fall around 4.35 billion years, ...

It's largely agreed that the moon was created around 4.5 billion years ago when a protoplanet collided with early molten ...

Linking analyses of the moon's gravity field with models of its earliest evolution, scientists tell a story of the moon turning itself inside out after it solidified from a primordial magma ocean. The ...

The moon was formed 4.5 billion years ago in a "giant impact" that left Earth with a two-hour day, according to new research. Scientists have long debated the circumstances which led to the formation ...

The moon may be more than 100 million years older than some scientists previously thought, according to a new study. The research, published Wednesday in the journal Nature, challenges the ...

Seismic waves created by earthquakes as they travel through the planet's interior change speed and direction as they move through different materials. Things like rock type, density, and temperature ...
