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
China is claiming that its enormous “Sky Eye” telescope may have picked up trace signals from a distant alien civilization, according to a recently posted and subsequently deleted report by Chinese scientists. Astronomers at Beijing Normal University have discovered “several cases of possible technological traces and extraterrestrial civilizations from outside the Earth,” according to a … Read more
So far no one has found evidence of intelligent aliens elsewhere in the cosmos. But if they do exist, they might be hanging out on Dyson spheres circling the husks of sunlike stars called white dwarfs scattered throughout the Milky Way, a new paper argues. And that’s there we should be focusing our search for … Read more
The Milky Way is home to millions of potentially habitable planets — and approximately four of them may harbor evil alien civilizations that would invade Earth if they could, new research posted to the preprint database arXiv (opens in new tab) suggests. The new paper, which has not yet been peer-reviewed, poses a peculiar question: … Read more
Why has humanity never been visited by aliens (that we know of)? The question has confounded scientists for decades, but two researchers have come up with a possible — and disturbing — explanation: Advanced civilizations could be doomed to either stagnate or die before they get the chance. The new hypothesis suggests that, as space-faring … Read more
