Spacecraft May Have Flown Right Through a Plume of Water on Jupiter's Moon Europa Spacecraft May Have Flown Right Through a Plume of Water on Jupiter's Moon Europa

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.

Intense Gravity of Super-Earths Could Trap Aliens on Their Home Planet Intense Gravity of Super-Earths Could Trap Aliens on Their Home Planet

Rocky worlds larger than Earth are commonplace in the galaxy, and a few of them may even be habitable. Which poses an interesting question: How difficult would it be for aliens living on these super-Earths to launch rockets into space, given the tremendous gravity? According to new research, it would be difficult to…

Hibernating Aliens Could Explain the Great Silence Hibernating Aliens Could Explain the Great Silence

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…

More Evidence That Aliens Aren’t Trying to Communicate With Us More Evidence That Aliens Aren’t Trying to Communicate With Us

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…

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

Lost Essay Reveals Winston Churchill Was Almost Certain Aliens Exist Lost Essay Reveals Winston Churchill Was Almost Certain Aliens Exist

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.…

SETI: KIC 8462852 Is Not Shooting Alien Laser Beams At Us SETI: KIC 8462852 Is Not Shooting Alien Laser Beams At Us

Everyone’s favorite alien-megastructure-that-never-was got another affirmation that it’s just a goddamn star today. According to SETI, there are NO EXTRATERRESTRIAL LASERS emanating from the baffling stellar body.

That So-Called Alien Megastructure Could Just Be a Distorted Star  That So-Called Alien Megastructure Could Just Be a Distorted Star 

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.

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

Here's More Evidence That Galactic Super-Civilizations Don't Exist Here's More Evidence That Galactic Super-Civilizations Don't Exist

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…

How SETI Will Understand Messages Broadcast by an Alien Intelligence How SETI Will Understand Messages Broadcast by an Alien Intelligence

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.

How We Could Detect an Alien Apocalypse From Earth How We Could Detect an Alien Apocalypse From Earth

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.

The Search for Alien Intelligence Got a $100 Million Boost The Search for Alien Intelligence Got a $100 Million Boost

Russian billionaire Yuri Milner has announced a new initiative called Breakthrough Listen, a 10-year project that will search for radio and light signals emitted by extraterrestrials. At a cost of $100 million, it’s the largest sum of money ever allocated to the effort.

What to Expect From Aliens When We Make First Contact What to Expect From Aliens When We Make First Contact

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.

This Animated Explanation Of The Fermi Paradox Is Fantastic

The Great Silence is a vexing problem we all love to speculate and argue about, but it’s not the most intuitive concept. This wonderful animated video by Kurz Gesagt explains the problem that is the Fermi Paradox and why our apparent isolation in the galaxy is so damned weird.

 A Scan Of 100,000 Galaxies Shows No Sign Of Alien Mega-Civilizations  A Scan Of 100,000 Galaxies Shows No Sign Of Alien Mega-Civilizations

A pioneering infrared scan of 100,000 galaxies by Penn State astronomers has failed to detect any signs of galaxy-spanning extraterrestrial supercivilizations. This result, though very preliminary, may be a sign that aliens aren't capable of conquering entire galaxies.

This New Infrared Telescope Could Help Us Detect Dyson Spheres This New Infrared Telescope Could Help Us Detect Dyson Spheres

The search for extraterrestrial intelligence just got a big boost, thanks to the introduction of a powerful new infrared telescope. In addition to scanning for pulses of infrared light, astronomers will use device to search for alien megastructures, such as Dyson Spheres.

Frank Drake: "It Would Be Silly" To Message Alien Life Today Frank Drake: "It Would Be Silly" To Message Alien Life Today

Frank Drake, creator of the eponymous equation formulated to predict the probability of finding communicative extraterrestrial life in our galaxy, thinks that actively transmitting messages into outer space (as opposed to listening passively for extraterrestrial communication) is a silly, expensive, and inefficient…

Experts Gather To Discuss Whether We Should Send Messages To Aliens Experts Gather To Discuss Whether We Should Send Messages To Aliens

This coming weekend at the annual meeting of the American Association for the Advancement of Science, experts will be discussing the potential benefits and risks of a SETI scheme in which messages about Earth — including the entire contents of Wikipedia — would be transmitted to hundreds of star systems.

Are Religious Beliefs Going To Screw Up First Contact? Are Religious Beliefs Going To Screw Up First Contact?

Are humans really prepared to meet an extraterrestrial civilization in this century? A new study suggests we're psychologically ill-prepared for this monumental event — and that the prominence of religious beliefs has a lot to do with it.
