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

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?

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

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?

The robotic Solar Orbiter spacecraft has obtained the first images ever taken of our sun's two poles as scientists seek a deeper understanding of Earth's host star, including its magnetic field, its ...

“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.

Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into ...

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.

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.

Recent research suggested the first and only moons seen around planets outside the solar system didn't actually exist; now, the scientists who initially found them are back to defend their discovery.
