A new class of exoplanet very different to our own, but which could support life, has been identified by astronomers, which could greatly accelerate the search

From the tallest cliff in the solar system to its largest impact basin, geological processes on other worlds are very similar to those on our own planet.

Researchers used decades-old radar data and found that some low-lying areas of Venus' crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.

Astronomers know a lot about what's in outer space – and think it's possible it never ends.

Two new NASA missions – VERITAS and DAVINCI+ – are headed to Venus. The missions will use radar and a probe to learn about Earth's hard-to-study and potentially prophetic neighbor.

How much energy does the internet use, and - given recent technological advances - could it ever run on renewable energy alone?

Test out scientific ideas, connect with your ancestors or just marvel at the beauty of nature.

The vast majority of people will be oblivious to what's going on above their heads.

Using carbon dioxide instead of oxygen in a key point in creating perovskite solar cells could remove a stumbling block to making them more widespread.

Nasa's sending its first missions to Earth's twin since 1990.
