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. Kane Basin, the widest section of the strait, is characterized by a gradient in windspeed with higher speeds in the center of the basin and lower winds in the eastern basin that is the result of sheltering by the steep topography of the upstream Washington Land peninsula.This question has plagued humankind since time immemorial. ![]() ![]() Higher windspeeds occur in the vicinity of Smith Sound and are associated with a left-hand corner jet. We show that model resolution plays a role in the representation of both the mean and extreme winds along the strait through the ability to represent this ageostrophic flow. The strait has a width that varies from ∼40 to ∼100 km and as such the wind field is typically ageostrophic and controlled by the pressure gradient in the along-strait direction. ![]() Here we use weather station data from the region as well as two reanalyses and an operational analysis with nominal horizontal resolutions that vary from ∼30 to ∼2.5 km to characterize the wind field in the vicinity of the strait. However, its remote location has limited our knowledge of the winds along the strait. The winds that blow along the strait play an important role in modulating ice and water exports from the Arctic Ocean as well as in helping to establish the Arctic's largest and most productive polynya that forms at its southern terminus. Nares Strait is the long and narrow strait bounded by steep topography that connects the Arctic Ocean's Lincoln Sea to the North Atlantic's Baffin Bay.
