Flybys of primordial black holes may occur once a decade. Tweaks to the orbits of planets and GPS satellites could give away their presence.

Astronomers have observed three types of black holes in the universe. Stellar-mass black holes formed from the collapse of a ...

Scientists say microscopic black holes could explain the elusive "dark matter" that makes up a quarter of all matter in the ...

Now, however, Pluto and that part of the solar system has moved away from the backdrop of the Milky Way into a sparser region of the night sky. With its Hyper Suprime-Cam (HSC), Subaru has discovered ...

Using the Subaru Telescope, astronomers have identified previously unknown celestial bodies in the outer Solar System, ...

"If there are lots of black holes out there, some of them must surely pass through our backyard every now and then." ...

Microscopic black holes might whizz through the inner Solar System once a decade — and scientists should be able to detect ...

According to a new study, if a primordial black hole passed within a few hundred million miles of Mars, it could shift the planet's orbit by about a meter -- causing a "wobble." ...
