Astronomers have observed three types of black holes in the universe. Stellar-mass black holes formed from the collapse of a massive star, intermediate mass black holes found in some star clusters, and supermassive black holes that lurk in the centers of galaxies.

If microscopic black holes born a fraction of a second after the Big Bang exist, then at least one may fly through the solar system per decade, generating tiny gravitational distortions that scientists can detect.

A new study suggests that a microscopic black hole might pass through our solar system once every decade or so.

Scientists say microscopic black holes could explain the elusive "dark matter" that makes up a quarter of all matter in the universe. But can it be proven?

Primordial black holes, which are smaller than their better-known cousins, visit the inner Solar System once a decade, simulations suggest.

"Primordial black holes do not live in the solar system. Rather, they're streaming through the universe, doing their own thing," said researcher Sarah Geller.

Astronomers have proposed a bold new detector for dark matter: the planet Mars. We know the position of the Red Planet with exquisite precision and if there was a certain type of dark matter passing through the Solar System,
