New Results Quash ‘Alien Megastructure’ Theory of Mysterious Dimming Star

The results are now in after a year-long, crowdfunded investigation into the star KIC 8462852, and to hardly anyone’s surprise, the strange dimming produced by this star doesn’t appear to be caused by an alien megastructure. That said, astronomers are now significantly closer to knowing the true reasons for the star’s odd behaviour. Read More >>

Wild New Theory Suggests Radio Bursts Beyond Our Galaxy Are Powering Alien Starships

Since their discovery ten years ago, fast radio bursts have confounded astronomers. These intergalactic pulses of radio energy have defied explanation, but a new theory suggests a technological origin, whereby aliens use these beams to propel their ships through space. Extremely speculative stuff, to be sure, but it’s an idea worth pursuing given just how weird these pulses are. Read More >>

This May Be the Best Explanation Yet For That Mysterious ‘Alien Megastructure’

A new paper from Columbia University suggests that Tabby’s star—the celestial object voted most likely to host an alien megastructure—is acting weirdly because it recently annihilated an entire planet, and the shattered remains of that planet are now producing strange flickering effects. It’s probably the best theory we’ve heard so far. Read More >>

Want to Find Aliens? Look for Planets That Have Become Stars

Jupiter is often referred to as a “failed star,” leading some futurists to wonder if our descendants might set it ablaze in a process called planetary stellification. A new study suggests this is indeed theoretically possible—and that we should be on the hunt for galactic aliens who have already converted their gas giants into stellar objects. Read More >>

The So-Called Alien Megastructure Just Got Even More Mysterious

Last fall, a little-known star called KIC 8462852 became our planetary obsession when astronomers said that its erratic flickering could be the result of an alien megastructure. Further observation of Tabby’s Star yielded no signs of aliens, but the sudden dips in luminosity continue to defy explanation. Now, things just got a bit weirder. Read More >>

We Might Finally Solve the ‘Alien Megastructure’ Mystery

Good news alien hunters! A Kickstarter to fund a year-long investigation into KIC 8462852—the star voted most likely to harbour an advanced alien civilisation—just got funded. Alien megastructure or not, we may finally get to the bottom of this bewildering, flickering star. Read More >>

Flawed Data Just Made That ‘Alien Megastructure’ Even More Unlikely

Remember all that fuss last year about the supposed discovery of an alien megastructure? A new study is taking issue with some of the data used in support of the theory, claiming that the observations were tarnished by the inconsistent use of telescopes down here on Earth. Read More >>

That ‘Alien Megastructure’ May Actually Be a Swarm of Cometary Fragments

An oddly dimming star located 1,500 light-years from Earth is causing all sorts of commotion in the scientific community, leading some to speculate that it may be an of alien megastructure. A new analysis of infrared data suggests a more natural explanation. Read More >>

What are the Odds of an Alien Megastructure Blocking Light From a Distant Star?

A strange star located 1,500 light-years from Earth is exhibiting strange flickering behaviour that’s leading some scientists to speculate that an alien megastructure is blocking the light. But what would such a structure be exactly and how likely is it that the Kepler space telescope has actually spotted one? Read More >>

21 Views of Workers Struggling With Megastructures

"To paint the Forth bridge" is a modern-day phrase equivalent to a "Sisyphean task": an endless job that can never truly be completed.* The gigantic struggle of maintaining—cleaning, painting, and repairing—the largest structures on earth is an awesome one, and it deserves recognition. That's the goal of our collection of photos below. Read More >>
