The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical ...

Scientists have gotten a never-before-seen look at an area around a large exoplanet 625 light-years away where moons like the ...

Billions of years ago, so the theory goes, something around the size of Mars smacked into Earth, spewing a whole bunch of dirt into space that eventually coalesced to form the Moon. This is called the ...

New study provides clearer insight into how the Moon formed and why its materials closely resemble those of Earth.

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 ...

The Moon formed a little later than previously assumed. When a Mars-sized protoplanet was destroyed in a collision with the young Earth, a new body was created from the debris ejected during this ...

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 ...

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 ...

The moon is sometimes called "two-faced" because the surface of its side perpetually facing away from Earth looks so ...

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 ...
