Nasa continues to find worlds that exist far beyond our Solar System. And now, the American space agency has confirmed the discovery of exoplanet number 6,000!
An exoplanet is a planet that orbits a star outside our Solar System. These planets are incredibly far away - some hundreds of light years from Earth - and scientists first started to discover them about 30 years ago.
The first exoplanet found around a star like our Sun was discovered in 1995. It's called 51 Pegasi b, and it's a giant gas planet, a bit like Jupiter in our own Solar System.
Since then, discoveries have been speeding up. Just three years ago, the total was 5,000 - since then another 1,000 exoplanets have been found.
In a video released to mark the moment, Nasa said: "We're entering the next great chapter of exploration - worlds beyond our imagination. To look for planets that could support life and to remind us the universe still holds worlds waiting to be found."
