The [research](), accepted for publication in *Monthly Notices of the Royal Astronomical Society*, **c**ould potentially open up huge new swathes of the universe to scrutiny by SETI scientists — thereby, the authors hope, increase our chances of spotting "powerful transmitters" in distant space. "I think for a while we’ve realized that when we make a SETI observation with a radio telescope, we are sensitive to not only the target star in the center of the field but also a patch of sky about the size of the Moon," study coauthor Michael Garret, a researcher at the University of Manchester and director of Jodrell Bank Center for Astrophysics, [told *Vice*](). "Other objects in the field include foreground stars and background stars in our own Milky Way," he added. "Until recently, we didn't know how to make use of this fact because we didn’t know the distance to these stars." ## Ready SETI Go But by using the European Space Agency's Gaia telescope, Garret and his colleague Andrew Siemion, director of the Berkley SETI Research Center and principal investigator for the Breakthrough Listen program, were able to obtain far more accurate measurements. From there, the pair were able to comb through more than 400 previous Breakthrough Initiative surveys of our galaxy, uncovering more than 140,000 objects that once went undetected in the various telescopes' snapshots. Among those "astrophysical exotica," [according to a press release](), were galactic nuclei, radio galaxies, interacting galaxies, and a galaxy whose gravity formed a gravitational lens. "It turns out that wherever you point your telescope, the field of view is going to include some interesting cosmic object," Garrett said in the *Vice* interview. Now that we know how to identify these once buried exotica, the thinking goes, our chances of stumbling on an alien signal are much improved — and it makes you wonder how much we might've overlooked. **More on SETI:** *[Swiss Government Scientist Says We May Be on the Brink of Discovering Alien Life]()* ## Author At Futurism, my work has often centered on bringing a sense of clarity and insight to complex topics ranging from the regulation of emerging technologies to the esoteric ideologies of Silicon Valley executives, while striving not to lose the poetic sense of awe inspired by often-obscure fields like astrophysics and quantum computing. I broke the story of CNET using AI to produce articles that turned out to be riddled with factual errors and plagiarism — a dam-breaking inflection point, as I've reported, that's inspired copycats and endless discourse while beguiling stakeholders ranging from tech giants to purveyors of spam around the web. My work at Futurism has been cited by publications including CBS News, the Los Angeles Times, Vice, Gizmodo, Engadget, the Verge, and Vanity Fair. I grew up in locales ranging from India to China, and now live in the exotic suburbs of Virginia. In my free time, I'm an avid reader of weird sci-fi literature, an aficionado of East Asian cinema, and, regrettably, a relapsed gamer. Allegedly, I’m working on a debut novel, currently untitled. ### Author social links [Bluesky]()
