Why Scientists Are Speculating About ‘Alien Superstructures’ Around an Irregular Star
We want to believe.
We may have neighbors — extraterrestrial neighbors.
Look between the constellations Cygnus and Lyra, and there sits a star, around 1,481 light-years away, named KIC 8462852. This star is the most interesting thing in the galaxy right now. Scientists have been noticing a mess of objects circling this thing, because it's been giving off unusual light fluctuations, unusual enough to be under consideration for one of the supercivilizations astronomer Jason Wright and his team have been looking for.
The Kepler Space Telescope has been collecting data, looking at light emissions from various stars, trying to find signs of life. However, the algorithm has trouble recognizing patterns that might qualify a star as part of an advanced civilization — sifting through this data requires a human touch (aka advanced pattern recognition). So, the citizen-scientist program “Planet Hunters” was founded.
Back in 2011, several of these scientists flagged this particular star as “interesting” and “bizarre.” Researchers were intrigued.
“We’d never seen anything like this star," Tabetha Boyajian, a postdoc at Yale who oversees the Planet Hunters, said in an interview with The Atlantic. "It was really weird. We thought it might be bad data or movement on the spacecraft, but everything checked out.”
The light pattern suggests there's a big mess of stuff circling the star. If the star were young, it would be expected to have a circle of debris surrounding it. But this is a mature star, so could scientist be seeing solar panels created by a Type 3 civilization to harness its energy?

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Torn between absolutism on the left and the right, classical liberalism—with its core values of compassion and incremental progress whereby the once-radical becomes the mainstream—is in need of a good defense. And Adam Gopnik is its lawyer.
- Liberalism as "radical pragmatism"
- Intersectionality and civic discourse
- How "a thousand small sanities" tackled drunk driving, normalized gay marriage, and could control gun violence
As Game of Thrones ends, a revealing resolution to its perplexing geography.
- The fantasy world of Game of Thrones was inspired by real places and events.
- But the map of Westeros is a good example of the perplexing relation between fantasy and reality.
- Like Britain, it has a Wall in the North, but the map only really clicks into place if you add Ireland.
The lost practice of face-to-face communication has made the world a more extreme place.
- The world was saner when we spoke face-to-face, argues John Cameron Mitchell. Not looking someone in the eye when you talk to them raises the potential for miscommunication and conflict.
- Social media has been an incredible force for activism and human rights, but it's also negatively affected our relationship with the media. We are now bombarded 24/7 with news that either drives us to anger or apathy.
- Sitting behind a screen makes polarization worse, and polarization is fertile ground for conspiracy theories and fascism, which Cameron describes as irrationally blaming someone else for your problems.
