Dark matter, as its name suggests, is incredibly dark—so dark, in fact, that it doesn’t interact with light or any other part of the electromagnetic spectrum.

However, new research suggests that future missions to the far side of the Moon could play a crucial role in determining the mass of individual dark matter particles.
