While the prospect of aliens was first launched by Penn State astronomer Jason Wright, almost everyone in the astronomy community agreed that the chances that this was the case were "very low."

An alien megastructure, called a Dyson swarm, was suggested as one explanation for what scientists have observed, but the most likely reason astronomers came up with was comets — a giant family of them.
