There is so much we first need to discover and learn before we can start predicting where and if advanced life exists.” I do not think the possibility of finding advanced life is black or white. It’s like hunting for needles in a haystack. Even if we could travel at the speed of light, there is no guarantee that we will know exactly where to look. “If we invented interstellar travel, where would we go first? We have the predictions of places for life, but they are still hundreds or more light-years away. “If advanced civilizations have existed before us, then they would have had ample time to develop interstellar travel and would have made it to Earth,” Sunil says.
“The Fermi Paradox is interesting because it contradicts the possibility of advanced life in our galaxy,” Harshini Sunil, an astronomy and physics undergraduate student at the University of Colorado Boulder, tells Astronomy. The simple question has since spurred scientists to better understand the possible reasons that we haven’t heard from any technologically advanced alien civilizations. The Fermi Paradox attempts to address the question “Where is everybody?” By most accounts, Fermi asked this deceptively simple question in 1950 during lunch with colleagues. Two of the most iconic insights related to the possibility of technological civilizations existing elsewhere in the universe are the Fermi Paradox and the Drake equation, which were formulated by Enrico Fermi and Frank Drake, respectively. “With that said,” he adds, “I am hopeful of the existence of extraterrestrial life, given the number of potentially habitable worlds and the ongoing exciting research into the origin(s) of life.” How likely are we to find life elsewhere in the universe? “The only correct answer to this question is that we don't know,” Manasvi Lingam, an astrobiologist and Assistant Professor in the Department of Aerospace, Physics, and Space Sciences at the Florida Institute of Technology, tells Astronomy. Still, the question remains: Are we alone? But in a recent May 2022 study published in the International Journal of Astrobiology, researchers identified a possible source of the Wow! Signal: a Sun-like star a bit more than 1,800 light years from Earth. Most now agree the Wow! Signal is unlikely to be from aliens.
The signal was so intriguing that astronomer Jerry Ehman enthusiastically wrote the word “Wow!” on the data printout.
15, 1977, and it lasted for 1 minute and 12 seconds. This very brief, but very intense, radio signal was detected by Ohio State University’s Big Ear Radio Telescope Aug. Perhaps the most tantalizing potential signal from an extraterrestrial civilization is the famous Wow! Signal. The current hunt for alien life includes: the Search for Extraterrestrial Intelligence (SETI) Institute, which has scoured the skies for radio signals from intelligent beings since its founding in 1984 the Kepler space telescope, which observed more than 500,000 stars during its mission, confirming more than 2,500 exoplanets and more recently, the James Webb Space Telescope (JWST), which just took its first direct image of an exoplanet. Despite our incredible technological advancements, we have never received a credible radio signal from, or even the teeniest trace of, extraterrestrial life beyond Earth. And yet, we still don’t have a conclusive answer. This question has plagued humankind since time immemorial.
