Solar System

Many stars in our galaxy exist in pairs. Now scientists are finding clues that our Sun may once have had a companion of its own. The question is, where did it go?

The Geminids are an astronomical highlight of the year, creating a spectacular show of shooting stars every December. Scientists are now starting to understand where they came from.

As space agencies venture onto the moons of Jupiter and Saturn to look deep below their frozen surface, might we find new forms of life there?

To understand the life that might survive deep below Mars' surface, we can look to some of the deepest, and oldest, forms of living organism on our own planet.

The Sun is going through a period of high activity, but it is nothing compared to an enormous solar event that slammed into our planet 14,000 years ago.

The Sun is extremely active right now, blasting the Earth with the biggest solar storms in 20 years. This is what it is doing to the rest of the Solar System.

Space launches are increasing and the rockets are getting bigger. What's the environmental impact on the surrounding areas, particularly when things go wrong?

China's Chang'e-6 mission is intended to bring back lunar samples but is also a stepping stone to much more ambitious space exploration.
