Researchers are calling on the public for help in identifying exoplanets – planets orbiting stars outside of our own Solar System.
The Planet Hunters Next-Generation Transit Search (NGTS), run by an international group of astronomers, has five years' worth of digital footage that needs sifting through.
"It is exciting to be able to involve the public in our search for planets around other stars," says astrophysicist Peter Wheatley from the University of Warwick in the UK and the lead of NGTS.
There's plenty of data to get through: Every 10 seconds, the NGTS telescopes capture shots of thousands of stars in the sky.
"The automated algorithms produce lots and lots of possible candidate transit events that need to be reviewed by the NGTS team to confirm whether they are real or not," says astronomer Meg Schwamb, from Queen's University Belfast in the UK.
