    In late August, the SETI (Search for Extraterrestrial Intelligence) Institute revealed that they had detected a strange signal that was 94 light years away from Earth. During the time of the signal’s discovery, senior astronomer for SETI, Seth Shostak, could only describe the signal as “interesting”. However, he rhetorically asks, “Could it be another society sending a signal our way?” Shostak, like many other scientists who had heard about the mysterious SETI signal, had hoped for signs of intelligent life beyond Earth and its atmosphere. As it turned out, the signal was nothing more than interference from a military satellite. While the signal turned out to be a false alarm, it brings into question whether the benefits of an interaction with intelligent, extraterrestrial life outweigh the negative implications that come with meeting a vastly different group of individuals. The debate about whether there should be an active attempt to communicate with intelligent extraterrestrials is popular. However, I hope to introduce the discussion about why “differences” between two species would prevent the two communities from interacting. To add some context to my question, the interactions possible between Earth and an extraterrestrial colony can be compared to two different countries meeting together for the first time. In a good scenario, the two countries each have information that they can exchange, and that will benefit the other country. One country will learn how to grow…

    There is a common belief that aliens likely do exist but if they did then they would only be bacteria, a microorganism. Geologist Peter Ward and astronomer Donald Brownlee both said that it is improbable that any life other than a microbe is somewhere else in the universe. They state that the earth is a rare case and that intelligent life somewhere else is close to impossible. Even microbes, they said, would be the greatest discovery in the history of science because it suggests a "universal…

    “Exoplanet Habitability”, Seager discussed her search for exoplanets, and the supplemental search for habitable planets. This search for habitable planets, largely involves the classification of exoplanets, including the mass, orbit, habitable zone, atmosphere, and more. These classifications are even more important when considering the fact that planets may be habitable even with slightly different characteristics than Earth. One is to look for biosignature gases which would indicate…
