according to NASA Science. But where exactly is the edge of the solar system? Well, it depends on your criteria. If you base it on where the planet's end you would say the edge is Neptune and the ...

Because they're surrounded by foul-smelling gases that are incompatible with the human sense of smell, living on the surface ...

A passing star may have kicked the weird moons of giant planets like Jupiter and Saturn into place, new research suggests.

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

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 ...

“It’s completely plausible for our solar system to have captured such an Oort cloud planet,” said Nathan Kaib, a co-author on the work and an astronomer at the Planetary Science Institut ...

An MIT study suggests that primordial black holes could be dark matter and might cause detectable wobbles in Mars' orbit.

Brown, who is among the co-discoverers of Sedna, told the publication, “Some of our earlier hypotheses, before we realized ...

The search for the elusive "Planet Nine," a world shrouded in mystery and debate, may soon be resolved. Advances in ...

Nathan Kaib, co-author of the study and astronomer at the Planetary Science Institute, stated it is plausible for the Solar System to have captured an Oort Cloud planet. Kaib emphasized that ...
