Albeit the chances that the cause is aliens is often dismissed, a $100m initiative called The Breakthrough Project plans on using the 100m Green Bank Telescope in West Virginia to listen for extraterrestrial signals from Tabby's Star, which has been "a subject of attention and controversy over its irregular dimming pattern."
One of the most favoured explanations for this behaviour is that a swarm of comet fragments is periodically blocking light from the star, which also known by its official designation - KIC 8462852.
One very remote and speculative idea - yet one that has attracted much attention in the media - is that the pattern is caused by some kind of artificial structure, or a collection of structures, around the star.
The co-director of the Breakthrough Listen programme, Dr Andrew Siemion, said he was sceptical of explanations that involved intelligent life.
