Astronomers might have just found a new way to discover alien planets.

A bizarre shadow cast on the disk of dust and gas surrounding the young star TW Hydrae is likely evidence of an unseen exoplanet orbiting within the disk, astronomers report in a new study.

The research team noticed the shadow after analyzing 18 years’ worth of observations of TW Hydrae, which is about 8 million years old and lies 192 light-years from Earth, in the constellation Hydra. The images, taken by NASA’s Hubble Space Telescope, showed that the shadow rotates around the 41-billion-mile-wide (66 billion kilometers) disk once every 16 years.
