Quote:What about that advanced alien megastructure? “Once you’re invoking arbitrary advanced aliens doing something with technology far beyond ours, then there isn’t very much that can’t be explained,” says Simon. “But we don’t really want to resort to that until we exhaust all of the possible natural explanations we can think of.”
Even Wright, the astronomer who postulated the alien megastructure in the first place, admits that it’s a last resort.
In the meantime, astronomers will continue to monitor the star. A successful crowdfunding campaign earlier this year raised over $100,000, allowing astronomers to secure time at the Las Cumbres Observatory Global Telescope Network, where they can observe the star for a year.
The hope is that Tabby’s star will soon drastically dim and they will be able to swing different ground-based and space-based observatories towards it. Catching a transit in as many wavelengths as possible should help pin down what is interfering with the star – be it a swarm of comets, an alien megastructure, or something else entirely.
