Astronomers have discovered a distant planet that they think could be completely covered in water, making it a prime target for future study by the James Webb Space Telescope.

The planet is called TOI-1452 b and it is located around 100 light years away from Earth, orbiting one of a pair of stars in the Draco constellation.
