A UFO expert claims aliens have hijacked a Nasa spacecraft and are using it to try to contact Earth.
Voyager 2, an unmanned probe that has been in space since 1977, is sending strange messages that are confusing scientists.
German academic Hartwig Hausdorf believes it is because it has been taken over by extraterrestrial life.
Since its launch, Voyager 2 has been sending streams of data back to Earth for study by scientists, but on April 22, 2010, that stream of information suddenly changed.
Nasa claimed that a software problem with the flight data system was the cause but Hartwig Hausdorf believes it could be the work of aliens.
This is because all other parts of the spacecraft appear to be functioning fine.
Voyager 2 carries a disk with greetings in 55 languages on it in case the craft encounters other life forms.
Edward Stone, a scientist on the project, said the disk, called the Golden Record, is a kind of time capsule, intended to communicate a story of our world to extraterrestrials.
