KIC 8462862, a distant star, flickers erratically. Among the possibilities: occlusion by an alien "megastructure" surrounding it in space.
Though it sounds far-fetched, and there's no other evidence of intelligence emanating from the system, the flickering's gotten weirder. The star's total output has diminished continuously over the course of four years.
Jason Wright, the Penn State astronomer who first suggested that Tabby’s Star might be the site of a vast alien construction project, agreed that the new analysis lends credibility to Schaefer’s claim of century-long dimming. “The new paper states, and I agree, that we don’t have any really good models for this sort of behavior,” he said. “That’s exciting!”
Keivan Stassun, an astronomer at Vanderbilt who disputed the idea of long-term dimming, said that Tabby’s star continues to defy explanation. “[Montet’s] intriguing new findings suggest that none of the considered phenomena can alone explain the observations,” he told Gizmodo. “In the end, figuring out this puzzle may require accounting for a combination of effects.”
Or, they just decided to get the Dyson sphere finished ahead of schedule.

NASA has funded a new research collaborative research effort between Harvard, the Smithsonian Institutions, and the University of Rochester to search for extraterrestrial intelligence (SETI). This is the first NASA grant for SETI in three decades and the first ever to search for signs of ET that aren’t radio transmissions. Instead, the scientists will look […]
In 1960, Frank Drake, an astronomer at the National Radio Astronomy Observatory, launched Project Ozma, the first scientific effort to listen for radio communications from extraterrestrials. Frank, now 90, is still serious about SETI, writing research papers and advising scientists who are listening to the stars for signs of intelligent life. (I came to know […]
Thirty year ago today, the space shuttle Discovery carried the Hubble Space Telescope into orbit, opening up a new vista on our place in the universe. In celebration of the anniversary, NASA released this astounding Hubble image of a region where stars are born in the Large Magellanic Cloud, one of the closest galaxies to […]
Time management and self-motivation, the ability to stay on task and achieve in the office or when you’re working with home, is the true test of any person’s professional mettle. While that’s easier said than done, those skills can be taught and developed as you’ll find in The 2020 Work From Anywhere Hacker Bundle. The […]
It’s easy to be instantly dismissive about most Bluetooth speakers, especially small travel-sized units. Over the past few years, makers of every shape, size, and variety have started pounding out Bluetooth speakers, many barely able to sound much better than your smartphone speaker, let alone provide the bass and volume heft of legitimate portable speakers […]
Did you know that you are free to change your auto insurance at any time? Maybe you do know that, but don’t want to deal with the inconvenience of changing providers. Or maybe you simply already think you have a great deal. The fact is that your car insurance is one of those expenses that […]
