Astrophysicist Warns: Aliens May Be Boring or Unreachable

Researchers are taking the emissions from the vicinity of exoplanet Proxima B seriously. But if it is truly a technological signal, what would follow?

Boring? How very un-Star Trek of them! But it’s possible, says Caleb A. Scharf, director of astrobiology at Columbia University (pictured). He worries that, “Perhaps other life in the universe is, in the end, utterly dull.” Why might he think so? He is reflecting on the recent report of what may be a technological signal at roughly 982.002 MHz, coinciding with the direction of Proxima Centauri. If it is, what might the aliens turn out to be like? There’ll be some initial oddities, some curiosities that aren’t quite the things we planned for. A dull carrier wave signal for instance. Over time more evidence will show up, until eventually it’s clear that there are lots of species out there, puttering…

New Sky Catalog Reveals Most Likely Sites for Alien Technology

“Exotica” lists phenomena for which conventional natural explanations don’t seem to work well

We’ve been looking at reasons why we don’t see extraterrestrials, even though many scientists are sure they must exist. One enterprising research group has now assembled Exotica, a catalog of strange phenomena in space, which might help us search more efficiently. If extraterrestrials exist and are technologically advanced, they would leave a “technosignature,” which might at first only be seen as astrange phenomenon in space: Breakthrough Listen, the initiative to find signs of intelligent life in the universe, today released an innovative catalog of “Exotica”—a diverse list of objects of potential interest to astronomers searching for technosignatures (indicators of technology developed by extraterrestrial intelligence). The catalog is a collection of over 700 distinct targets intended to include “one of everything”…
