Nasa news alien life12/31/2023 “With proper design, these tiny probes would reach the Earth or other Solar system planets for exploration, as the parent craft passes by just like ‘Oumuamua did.” What’s more, the report explains, astronomers wouldn’t be able to see the “spray of mini-probes” – or “dandelion seeds” – because they wouldn’t reflect enough sunlight for existing survey telescopes to pick up.ĭoes this mean that little green men have actually touched down, expelled from a craft like ‘Oumuamua as it continues its interstellar journey? Given what we know about organic life, probably not. “In principle, a multitude of tiny devices can be released from a mothership that passes near Earth.” “Once an Earth-like planet is targeted, an interstellar device can plunge into its atmosphere,” Loeb and Kirkpatrick say. Like NASA, aliens could identify distant habitable planets by examining the light they filter out when passing in front of their home stars. The researchers compare this to NASA missions that often involve parachuting technology onto, say, the surface of Mars during a flyby. Taking inspiration from ’Oumuamua – a mysterious oblong object that recently passed through our solar system, sparking waves of speculation about its origin – the researchers speculate that an “artificial interstellar object could potentially be a parent craft that releases many small probes during its close passage to Earth”. The report also outlines the methods that alien civilisations might have used to infiltrate our civilisation with their research devices. “Since most stars formed more than a billion years before the Sun,” it adds, “it is possible that other technological civilizations predated ours by the amount of time needed for their devices to reach Earth.”st-block-4 Looking at the distance that their crafts would have to travel from planets orbiting distant, Sun-like stars, it notes that they could make the journey in less than a billion years. More specifically, the report comes to the conclusion that it’s feasible that alien life has already visited our home planet. NASA engages theologians to prepare humanity for alien contact.Our universe was made by aliens in a lab, theorises Harvard scientist.Unravelling the conspiracies about America’s UFO sightings.But what if intelligent alien life is already watching us and learning about our civilisation without us knowing it’s even there? According to a draft document released by the head of the Pentagon’s UFO investigation arm earlier this month, that’s a very real possibility.Īuthored by Sean Kirkpatrick, the director of the Pentagon’s All-Domain Anomaly Resolution Office (AARO), and Avi Loeb, the chairman of Harvard’s astronomy department (and founder of the ET-hunting Galileo Project) the research report outlines the possibility that aliens have been able to travel to Earth by analysing the physical constraints of spaceflight. This means that today’s scientists on Earth might not be able to detect commonly assumed signs of extraterrestrial life, and they might give up on planets that are actually inhabited, according to a new study in the journal Astrobiology.Many people here on Earth are devoted to detecting signs that we aren’t alone in the universe, from amateur conspiracy theorists, to the minds behind professional research centres such as SETI and the Galileo Project. Despite the fact that our planet was teeming with mostly microscopic life for three billion years, levels of oxygen and methane - gases often produced by metabolizing organisms - would have been too low to be noticed from afar. To a distant observer peering through a telescope, even Earth would not have shown signs of life through most of its past. It will be exceedingly complicated to figure out whether there’s actually any life or potential for it on such planets, based on new research into our own evolving world. But don’t prepare for first contact just yet. (Inside Science) - It seems like every day that astronomers discover another possibly habitable world, like Proxima Centauri b, our closest exoplanent neighbor, and TRAPPIST-1f, one of seven recently discovered Earth-sized planets orbiting the same star.
