Section 1.1: The Cultural Obsession

Few things unite Americans like our fascination with aliens. This interest is evident in pop culture, epitomized by the 1980s classic, E.T., which became the highest-grossing film of its time, reigning supreme at the U.S. box office for 16 weekends—a record that stands unbroken. As a child, I was enchanted by the film, and even as an adult, it remains a delightful watch. The charm of that sweet, large-eyed alien is hard to resist. If you're unfamiliar with this iconic character, one might wonder what planet you inhabit!

The intrigue surrounding UFOs has long been a driving force behind Hollywood's creativity, leading to a multitude of science fiction narratives. We often find ourselves pondering our reactions upon encountering such beings—would we greet them with a handshake, scream in terror, or flee? The thought of having a flying saucer land in our backyard is both exhilarating and daunting.

Historically, our imagination has depicted aliens as small, green humanoids, yet they might simply be microbial life forms existing in distant realms. The roots of this national fascination can be traced back to 1947, when Kenneth Arnold, an amateur pilot, reported seeing nine shiny unidentified objects over Mount Rainier, claiming they sped by at an astonishing 1,200 miles per hour. Whether he truly witnessed these phenomena remains a matter of debate, but his account undoubtedly sparked the phenomenon known as the UFO-industrial complex.

According to a survey by the Pew Research Center, 65% of Americans believe in the existence of intelligent life beyond our planet. But what’s unfolding in the present day?

Just as it seemed the alien narrative had quieted, a new wave of excitement emerges, fueled by advancements in AI. Scientists are once again turning their attention to the cosmos in search of our green companions.

Section 1.2: The Scientific Pursuit

For over 60 years, NASA has spearheaded the Search for Extraterrestrial Intelligence (SETI) project, employing the Green Bank Telescope and similar radio observatories to listen for possible signals from intelligent life forms.

Unfortunately, researchers have faced the challenge of sifting through vast amounts of data to distinguish terrestrial signals from those that might originate from elsewhere in the galaxy. Manually analyzing this data is impractical, leading to the common use of algorithms designed to identify what astronomers believe could be extraterrestrial communications. However, these algorithms sometimes yield false positives, mistaking signals from everyday technology for alien communications or missing signals that don't fit expected patterns.

In contrast, machine learning algorithms present a transformative solution.
