Scientists have discovered that, even in "pristine" solar systems, planets exhibit a bit of a tilt.

Five of the Uranus moons might be ocean worlds − and if there’s water, there might be life.

A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been

The Moon was formed when it collided with Earth billions of years ago.

Upcoming NASA missions will help scientists understand the composition of asteroids – which could inform companies one day hoping to commercially mine asteroids.

Solar energy is set for a rapid expansion – but only if several barriers are overcome, according to new research.

A more active Sun could disable satellites and affect electrical grids on Earth.

The international quest for green energy is reliant on ‘sacrificial zones’ in developing countries.

Some power plants don’t have massive smokestacks or cooling towers – or even a central site.

Conventional systems for producing hydrogen depend on fossil fuels, but the new system uses only solar energy.
