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 ...

Eons ago, in the frigid depths of our solar system, a dramatic collision occurred between two icy worlds. Instead of a catastrophic smash-up, the two bodies "kissed," merging temporarily like a ...

How did the Moon form? Was it from a collision, as has been the longstanding theory, or could it have been captured by the Earth early in our planet’s formation? This is what a recent study published ...

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 ...

Research into the formation of the moon was conducted by scientists at the Weizmann Institute of Science in Rehovot, Israel and the Technion-Israel Institute of Technology located in Haifa. Results of ...

One of the oldest unsolved riddles in planetary science concerns the origin of the moon. Over a century ago, George Darwin proposed that tidal and centrifugal forces on a rapidly rotating proto-Earth ...

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 ...

A research team from the University of Göttingen and the Max Planck Institute for Solar System Research (MPS) has discovered another piece in the puzzle of the formation of the moon and water on Earth ...

(CNN) — About 3.8 billion years ago, two massive canyons likely formed on the moon in a span of less than 10 minutes, according to new research. The extraordinary formations, each comparable in size ...

Researchers from NASA's Ames Research Center have created the most detailed simulations of this impact ever, and the results are surprising. Instead of taking months or years, the new research ...
