In Brief
Our moon, a glimmering staple in our night sky was once just a scattering of dust and rock. So, how did it become the cosmic object that we know today?

The mystery of the Moon’s formation is one that has captivated scientists for as long as human beings have been able to contemplate the stars. Previously, the most viable theory suggested that the Earth and a hypothetical planet named “Thea” collided at some point in the very distant past. When the collision occurred, tons of debris was ejected into space, which coalesced into the Moon we still see hanging resolutely in the night sky.
