Earth may sport a thick coat of superlong dark matter "hairs," a new study suggests.

Astronomers think dark matter — a mysterious, invisible substance that neither emits nor absorbs light, and is about six times more common than "normal" matter — forms fine-grained but incredibly long streams throughout the universe.

"A stream can be much larger than the solar system itself, and there are many different streams crisscrossing our galactic neighborhood," study author Gary Prézeau, of NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement.
