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 ...

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon ...

Over 4.6 billion years ago, the early Earth emerged from a swirling disk of gas and dust encircling the young sun. This primordial material collided and coalesced, forming larger bodies through 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 ...

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 ...

That timeline is based on analyses of lunar rock samples from NASA’s Apollo missions. But the new study suggests that the moon formed earlier — around 4.51 billion years ago — and then experienced a ...

“There’s a huge difference between the modern elemental makeup of the Earth and Moon and we wanted to know why,” said NASA planetary scientist Justin Simon. “Now, we know that the Moon was very ...

"For the first time, we have physical evidence showing us what was happening in the moon's interior during this critical stage of its evolution, and that's really exciting." When you purchase through ...

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 ...
