![]() ![]() ![]() “We’re looking at our closest neighbors and kind of trying to understand our little neighborhood of the galaxy.”Īlthough from our vantage point today we may still be invisible to any extraterrestrial civilizations, it’s nice to think that one day, we might be able to say hello. Canadian telescope finds mysterious radio flashes from deep space Haul from new radio array includes a second repeating fast radio burst About the author. 5 500 galaxies visible in Hubble’s ‘Deep Field’ view, covering a patch of sky about half the diameter of the moon. “Space is really, really huge, and these stars are all really far away from us compared to things we’re used to as people,” he says. In 1977 astronomers detected the Wow Signal, a short powerful burst of radio waves from deep space. “With both Kepler and Gaia, one of the really big advantages was that they were able to sort of stare for a long time at the stars,” says Douglas Caldwell, a SETI researcher and instrument scientist for the Kepler mission.Ĭaldwell says missions dedicated to specific science goals like Gaia offer a kind of precision that he hopes will bode well for future astronomical discoveries. Mysterious radio signals from space have been known to repeat, but for the first time, researchers have noticed a pattern in a series of bursts coming from a single source half a billion. But Kepler was made to observe one patch of sky for longer periods of time-the perfect way to track exoplanets using the transit method. TESS spends months looking at different sectors of the universe in its hunt to find exoplanets, and Gaia seeks to create a three-dimensional map of the entire Milky Way. Astronomers have detected a repeating radio signal from an exoplanet and the star that it orbits, both located 12 light-years away from Earth. Over 95 of FRBs discovered so far have been detected just once and then never. The radio emissions from such stars were initially believed to be aliens when such signals were first detected in 1967. Meanwhile, much of our own solar neighborhood is still unexplored, but that’s where missions like TESS, Gaia, and Kepler come in. Fast radio bursts are powerful but fleeting bursts of radio waves emanating from tumultuous sources in deep space. ![]()
