Once life gains even the tiniest foothold on a planet, it may have the power to transform that world, forcing us to broaden our definition of “habitable,” new research suggests. We don’t really know where life might arise. We have only one example of a life-hosting planet, Earth, which started to get interesting perhaps only … Read more
Aliens may be waiting until a cosmic version of “high noon” to send out their signals to us, scientists have suggested. In a new study, researchers hunted for technological signs of E.T. during the moments when exoplanets pass directly in front of their suns, from Earth’s point of view. These exact moments could be the … Read more
Scientists have proposed another use for the world’s largest gravitational wave observatory: scanning for the ripples in space-time left in the wake of gargantuan alien spaceships. Gravitational waves ripple out when objects with mass move through space. Bigger objects — such as planets, neutron stars or black holes — produce more prominent gravitational waves. These … Read more
One of the world’s largest telescopes has just joined the hunt for signs of alien life elsewhere in the cosmos. Since 2016, the Breakthrough Listen project has been quietly using radio telescopes to listen for unusual radio signals, or technosignatures, from potential advanced extraterrestrial civilizations within the Milky Way. The project, launched in part by … Read more
A team of scientists has proposed building an “interstellar interceptor,” a spacecraft capable of getting up-close and personal with the next asteroid or comet to enter the solar system. So far, astronomers have spotted two such objects whizzing through our star system: The cigar-shaped interstellar visitor ‘Oumuamua, which was first spotted in October 2017 and … Read more
Crop circles are a very straightforward phenomenon: They are a type of landscape art made by humans. Despite evidence to the contrary, some people remain convinced that crop circles were made by aliens brought by UFOs. But how did unidentified flying objects come to be linked with flattened expanses of cereal grains? And why have … Read more
If extraterrestrial life sent us a message tomorrow, how would humanity respond? According to researchers, we don’t know yet — and that’s a problem. That’s why, for the first time in 35 years, a team of policy experts and scientists have united to establish a set of alien-contact protocols for the entire world to follow … Read more
Ancient microbial life on Mars could have destroyed the planet’s atmosphere through climate change, which ultimately led to its extinction, new research has suggested. The new theory comes from a climate modeling study that simulated hydrogen-consuming, methane-producing microbes living on Mars roughly 3.7 billion years ago. At the time, atmospheric conditions were similar to those … Read more
Researchers may have pinpointed the source of a famous supposed alien broadcast discovered nearly a half century ago. The prominent and still-mysterious Wow! Signal, which briefly blared in a radio telescope the night of Aug. 15, 1977, may have come from a sun-like star located 1,800 light-years away in the constellation Sagittarius. “The Wow! Signal … Read more
Pentagon officials speaking at the first public hearing on UFOs since the 1960s have shown previously classified footage of an unidentified aerial phenomenon (UAP), a split-second video of a metallic sphere zooming across the flight path of a military jet. The object, captured through the cockpit window of an FA-18 fighter jet in 2021, was … Read more
