Why a Mission to a Visiting Interstellar Object Could Be Our Best Bet for Finding Aliens

Life may exist elsewhere in the Milky Way galaxy, though try as they might, scientists have yet to detect any sign of it. Part of the problem has to do with the size of space; finding traces of organic substances or the waste signatures of alien megastructures isn’t easy at such cosmic distances. Fortunately, there’s the possibility that alien life will come to us in the form of interstellar objects. Read More >>

A New NASA-Led Project Means the Search for Aliens Is Heating Up

To date, scientists have catalogued more than 3,500 exoplanets, some of which may even be capable of fostering life. But we simply don’t know. The ability to detect life on distant worlds still eludes us, but a new project coordinated by NASA now takes us a significant step closer to achieving that goal. Read More >>

Our Galaxy Might Be Teeming With Habitable Exomoons

There are eight planets in our Solar System (sorry Pluto), but collectively, these planets host over 175 moons, one or two of which may even harbour life. Indeed, our galaxy, based on what we observe here, could be bursting with exomoons, a significant number of which may be capable of fostering life, according to new a new study. Read More >>

Interstellar Asteroids Like ‘Oumuamua Could Rewrite the Origins of Life on Earth

Late last year, astronomers detected the first known interstellar asteroid, dubbed ‘Oumuamua. New research suggests these exotic objects are more abundant than we thought, an observation that boosts the panspermia hypothesis—the idea that asteroids seeded life on Earth. At the same time, the presence of so many foreign objects in our Solar System could also change the way we search for extraterrestrial life. Read More >>

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 >>

Preliminary Scan Suggests This Interstellar Visitor Is Not an Alien Spaceship

On October 19, 2017, astronomers witnessed the first known interstellar asteroid—a bizarre, cigar-shaped rock that, just as quickly as it entered into our Solar System, exited in a hurry. Not satisfied that ‘Oumuamua, as it’s been named, is just an odd asteroid, astronomers from Breakthrough Listen recently tuned their Green Bank telescope into the object to see if it’s an alien spaceship or some kind of probe. The preliminary results are now in and—brace yourself—it’s still a rock. Read More >>

An Earth-Sized Space Shield to Protect Us From Solar Storms Is Less Crazy Than It Sounds

Every 100 years or so, our Sun gives off a great big belch that sends an intense wave of charged particles towards Earth. This wasn’t a problem in the past, but our high-tech civilisation is now disturbingly vulnerable to these solar storms. A new study quantifies the economic risks posed by these extreme solar storms, while also proposing a super-futuristic solution to the problem: an Earth-sized shield built in outer space.

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 flourish to the greatest extent possible. How very convenient. Read More >>

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 intelligence. 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 Might Be Our Best Shot at Finding That ‘Alien Megastructure’ 

Since it was first suggested that the flickering star known as KIC 8462852 might be a Dyson Sphere, telescope-toting astronomers associated with the search for extraterrestrial intelligence (SETI) have been scouring the system for signs of aliens. Now, the most well-funded SETI program on Earth—UC Berkeley’s Breakthrough Listen—is getting in on the hunt, too. Read More >>

New Kickstarter Wants to Reissue NASA’s Golden Record

Launched in the late 1970s, the two Voyager space probes were equipped with a golden record containing sounds and images of life on Earth. Intended for alien consumption, this record has never been made available to the public in its intended form. An exciting new Kickstarter is now seeking to overcome this egregious oversight.

What That “Strong Signal” From a Nearby Sunlike Star Really Means

Earlier this week, news made the rounds that a team of Russian astronomers had detected an unusually strong signal emanating from a nearby sunlike star — a possible indication of an alien civilisation. Here’s what the detection of this signal really means, and why it’s probably not ET. Read More >>

Alien Hunters Spot Freaky Radio Signal Coming From Nearby Star

Astronomers using the RATAN-600 radio Telescope in the Russian Republic of Karachay-Cherkessia have detected an unusual signal emanating from a star located about 94 light-years from Earth. It’s not clear if the signal is being transmitted by aliens, but the researchers say we should keep a close watch on this intriguing new extraterrestrial candidate. 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 >>
