What’s Orbiting a Distant Star Will Astonish You

Or not.

Citizen scientists have been keen on a particular star since 2011 for its irregular light pattern, observed through Kepler Space Telescope. Irregular light patterns indicate object moving between us and the star, which could be planets, asteroids, tentacles of space squid, or the Borg. Any of those very realistic possibilities. The astronomers noted the star does not appear young, so debris surrounding young stars was ruled out. What could surround a mature star like this?

Jason Wright of Penn State suggested “the star’s light pattern is consistent with a ‘swarm of megastructures,'” Ross Anderson of The Atlantic reports, “perhaps stellar-light collectors, technology designed to catch energy from the star.

“When [Boyajian] showed me the data, I was fascinated by how crazy it looked. Aliens should always be the very last hypothesis you consider, but this looked like something you would expect an alien civilization to build.”

The science-side of the Interwebs has been abuzz with this news, but what can be understood from this observation? An article published in Scientific American earlier this year, which mentions Wright’s research, states nothing has been found. Writer Lee Billings explains Wright’s team’s goal.

They looked for the thermodynamic consequences of galactic-scale colonization, based on an idea put forth in 1960 by the physicist Freeman Dyson. Dyson postulated that a growing technological culture would ultimately be limited by access to energy, and that advanced, energy-hungry civilizations would be driven to harvest all the available light from their stars. To do that, they might dismantle a planet or two as feedstock for building star-enveloping swarms of solar collectors. A star’s light would fade as it was encased in such a “Dyson sphere

Dyson himself is not discouraged by finding nothing. “Our imaginings about the ways that aliens might make themselves detectable are always like stories of black cats in a dark room,” he said. “If there are any real aliens, they are likely to behave in ways that we never imagined.”

Which means they probably aren’t hoping to eat us.
