August 2018 rolled in with a bang, literally, as explosions rocked Caracas, Venezuela on Saturday during a speech by President Nicolas Maduro—and government officials later said bomb-carrying drones were to blame. If the accounts of an attempted assassination using unmanned aerial vehicles is confirmed, the New York…

Reported UFO sightings have been declining in the United States for the last few years, according to the statistician tasked with making sense of all the data acquired by the leading civilian UFO investigation group.

SETI enthusiasts have devised all sorts of complicated ways for us to find signs of alien life, but a new paper suggests we may be overthinking it. Instead of looking for megastructures and spaceships, we should consider something a bit more obvious: alien satellites and space junk in orbit around distant exoplanets.

Sometimes, scientists have the answers all along—they just don’t think to ask the question. For example, it appears that in 1997, the Galileo orbiter flew through a jet of water shooting out from Jupiter’s moon Europa without even trying.

We have yet to find any traces of extraterrestrial intelligence, a vexing problem known as the Fermi Paradox. A new solution to the “where are all the aliens?” conundrum suggests that advanced aliens do exist—but they’re in a self-imposed state of hibernation, waiting for a future era of the cosmos in which they can…

Some SETI researchers believe the best way to detect aliens is to search the skies for their laser beams. In the largest survey of its kind, astronomers scanned 5,600 stars in search of these optical signals—and they found...absolutely nothing. Nada. Zilch. Here’s what that means to SETI and the ongoing hunt for alien…

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…

Unlike so many politicians these days, Winston Churchill held a deep admiration for learning and science. A rediscovered essay—forgotten in a museum for nearly sixty years—reveals Churchill’s astoundingly scientific thoughts on such topics as cosmology, the origin of life, and the likelihood of extraterrestrials.…

The Kepler Space Telescope recently picked up unprecedented flickering behavior from a distant star, leading to speculation that—among other things—it might be an alien megastructure. Now, some astronomers are saying it might just be caused by a rapidly spinning and irregularly shaped star.

A strange star located 1,500 light-years from Earth is exhibiting strange flickering behavior 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?

Earlier this year, a scan of 100,000 galaxies showed no signs of alien mega-civilizations, dashing the hopes of those longing for a close encounter of the extra-terrestrial kind. A follow-up analysis of the data suggests it’s even worse than we thought, concluding that advanced galaxy-spanning civilizations don’t…

Imagine the day when we finally receive a signal from an extraterrestrial intelligence, only to find that there’s a message embedded within. Given that we don’t speak the same language, how could we ever hope to make sense of it? We spoke to the experts to find out.

It’s generally assumed that we will eventually find signs of life in the galaxy. But rarely do we consider searching for advanced civilizations that have destroyed themselves. Here’s how we could do it—and what the search for dead aliens could tell us about our own future.

Given the vastness of space, it may only be a matter of time before we make contact with intelligent extraterrestrials. But how might an alien civilization react to such a monumental meet-and-greet, and can we possibly know their intentions? Here’s what we might expect.
