Astronomers have observed an object that originated from beyond our solar system, thought to be an interstellar comet, speeding through our celestial neighborhood.

Find out where we fit in the solar system, with the Super Movers Crew who have a special song and routine from the TARDIS and get your Key Stage 2 pupils moving.

The location of the solar system's outer boundary is a point of contention among astronomers. There are three possible candidates, which "all have merit." But which one is best?

Our Solar System possibly survived a supernova because of how the Sun formed The gas that produce stars also cushion them from the blast of nearby supernovae.

The bold question-askers at What If explore why having a black hole in our Solar System would be a catastrophic scenario.

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

The solar system has many more moons than the one we can see in the sky. But how many do we actually know about? And how many more are waiting to be discovered?

It’s possible that this object was first ejected to the Oort cloud, the most distant region in our solar system, which is home to many comets, and then sent back,” Cheng adds.

A possible cousin of Pluto seems to be circling the far reaches of the solar system. The dwarf planet candidate 2017 OF201 travels in a superwide orbit, with the sun relatively near one end of its ...

THIS work is of the type that in some libraries is politely classified as ‘paradoxical science.’ Among the author's special contributions to the theory of the solar system is the hypothesis ...
