    • Is E.T. phoning us from Proxima Centauri? The answer to weird signals happening in the universe is never aliens, until maybe it is. Earlier this month, researchers announced that they had captured a very mysterious beam of energy in the radio part of the electromagnetic spectrum at 980 megahertz, coming from the closest star to our own.
    • Alien bacteria might live in the clouds of Venus. Astrobiologists were a-twitter with anticipation and skepticism in September when news broke of potential evidence of life in the upper clouds of Venus.
    • 'Oumuamua could still be an alien artifact. Two years ago, scientists spotted a cigar-shaped object hurtling through the solar system. Dubbed 'Oumuamua, the entity is considered by most to be an interstellar comet flung out from around another star.
    • Navy declassifies UFO videos but don't believe the hype. A fair number of Earthlings don't care what ambiguous evidence scientists come up with to show that aliens are out there.
    • 1976, The Viking Mars landers detect chemical signatures indicative of life. Tests performed on Martian soil samples by NASA’s Viking landers hinted at chemical evidence of life.
    • 1977, The unexplained extraterrestrial “Wow!” signal is detected by an Ohio State University radio telescope. In August 1977 an Ohio State University radio telescope detected an unusual pulse of radiation from somewhere near the constellation Sagittarius.
    • 1996, Martian “fossils” are discovered in meteorite ALH84001 from Antarctica. NASA scientists controversially announced in 1996 that they had found what appeared to be fossilised microbes in a potato-shaped lump of Martian rock.
    • 2001, More rigorous calculations connected to the 1960s “Drake equation” suggests that our galaxy may contain hundreds of thousands of life-bearing planets.
  2. Jan 18, 2021 · One group of researchers decided that the best explanation was that 1I/2017 U1 was a “miniature comet” whose tail had gone undetected because of its “unusual chemical composition.” Another...

    On and off over the past decade, I’ve used radio telescopes to perform wide ranging experiments to search for technosignatures– signs of technological civilisations on planets elsewhere in our galaxy (the Milky Way). But after decades of many teams of experts using powerful telescopes, we still haven’t covered much territory. If the Milky Way is co...

    The vast volume of the universe makes it very difficult to achieve interstellar travel, receive signals, or communicate with any potential far-off lifeforms (at least according to the laws of physics as we know them). Speeds are limited to the speed of light, which is around 300,000 km per second. It’s pretty fast. But even at that speed it would t...

    Could it be aliens have crashed on Earth and the US government is just covering it up, as Republican Congressman Tim Burchett claimed in his reaction to the hearing? For airlines belonging to the International Air Transport Association, the chance of plane crash is about one in a million. That begs the question: do we think an alien spacecraft that...
