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.

This year’s episode of the grand meteor shower the Leonids will peak on Monday morning before dawn. The meteors are bits of debris dropping off the comet Tempel-Tuttle that intersects Earth’s orbit every November. Unfortunately, it may be tough to see many shooting stars because activity this year will be low and the waning gibbous […]
David Schneider built his own radio telescope out of roof flashing, an empty paint thinner can, a free software-defined radio app, USB receiver, and a length of coaxial cable. The whole project cost him less than $150 and he’s already used it to detect galactic hydrogen and monitor the motion of our Milky Way galaxy’s […]

Once you’ve cut steak or poultry with some actual quality knives, it’s really tough to go back to those budget blades you bought at the department store a couple of decades ago. Consider that a fair warning about this 5-Piece Professional Damascus Chef’s Kitchen Set. The holiday discount makes it easy to buy for a […]
Concerned about your eyesight? You probably should be. And we’re not just talking about seniors here. Young or old, we’re all at risk of coming down with vision issues Most of us might get a vision test only once every couple of years or so when we get a new pair of glasses – if […]
We love our smartphones and tablets, but we also love to write. For a while now, there hasn’t been a workable solution. Either hook it up to a keyboard (which defeats the purpose of a portable gadget) or resign ourselves to typing on tiny, unresponsive glass icons. Looks like technology has finally caught up to […]
