moodboard: A star 100 Light years from Earth pulsed twice, this strange occurrence maybe have originated from artificial origins, i.e., Aliens, the last option on the list which is not even on this 'list' of possibilities.

From Physics.org:

"None of these explanations are really satisfying at this point," he said. "We don't know what kind of object could produce these pulses or how far away it is. We don't know if the two-pulse signal is produced by something passing between us and the star or if it is generated by something that modulates the star's light without moving across the field. Until we learn more, we can't even say whether or not extraterrestrials are involved!"
