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 >>

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 >>

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 >>

New Calculation Shows We’ll Make Contact With Aliens in About 1,500 Years

The disturbing Fermi Paradox suggests we should have made contact with an extraterrestrial civilisation by now, yet we haven’t. By applying a 500-year-old philosophical principle, a Cornell University researcher has shown that the Great Silence is not unexpected—we just need to give it more time. Read More >>
