    In late August, SETI (Search for Extraterrestrial Life Institute) revealed news of a peculiar signal found 94 light years away from Earth. SETI had hoped that this would be a crucial piece of evidence that revealed the presence of extraterrestrial life. However, only a few weeks after the initial announcement, the signal was debunked to be no more than an interference from a military satellite. While many scientists were disappointed by the news, it perhaps was the most favorable outcome of the…

    Although many people believe that extraterrestrial life is all fictitious, consumers should keep an open mind because first, with a galaxy and universe as big as ours how could one possibly believe that Earth is the only planet capable of sustaining life. Second, there have already been aspects found on Mars to make one reconsider any opinion there was over the topic. Lastly, it is possible to come across a planet or a moon which has the required ingredients to sustain a form of life. Not human…

    signals out into space with the hope that they will eventually hit their desired target and result in a response, but calculating the probability of success is a highly technical field that has a great deal of research associated with it. So what factors go into this statistical chance? Besides resting on the sheer existence of another life form, the probability of successfully communicating depends on various technological factors: the chance of the signal being sent…

    Aliens have been questioned for ages. There are stories, folktales, movies, and books all based on the topic of extraterrestrial life. Research has been done, yet sadly, the conclusion is still unknown. Experts show that extraterrestrials may exist. They may exist because there is proof they exist, there has been sightings and encounters involving extraterrestrial life forms, and there has been scientific reports that other planets have the ability to sustain life. It is possible that aliens…

    As of the 21st century, it is no longer controversial to believe in the existence of extraterrestrial life. While in the 16th century, a belief that life existed beyond Earth and its atmosphere may have led to a public execution (like it did for astronomer, Giordano Bruno), the same belief is held by 54% of Americans today. Given the evidence gathered through advanced space exploration and technology, the scientific community, as well as the general population, is more inclined to believe in…

    wondrous objects in space. Space has, for some, become a land of fantasy and storytelling. This has led some people to come up with conspiracy theories about space and extraterrestrial life that are absolutely absurd. One of the most interesting theories is that President Obama was teleported into space in the 1980s as part of an elite team that was trying to make contact with aliens. Another theory is that NASA’s missions to the satellites of Jupiter were simply a ploy because, in reality,…

In the past, ideas thoughts and knowledge was stored in scrolls, books, hieroglyphics, stone carvings, and held in massive libraries of the wealthy. Since then we have significantly advanced and developed sophisticated ways of storing and…

    possibility of interstellar travel, but not necessarily the possibility of intelligent life. The paradox however is frequently interpreted to mean that the absence of contact or artifact is evidence that extraterrestrial intelligence does not exist. The “they are not here; therefore they do not exist” argument was not introduced by Fermi, but by astrophysicist Michael Hart. Hart, in a 1975 paper published by the Royal Astronomical Society, argued that if there were intelligent beings in the…

    Does that simply mean they’re not out there at all? Fermi’s paradox would argue that’s exactly what it means. The Fermi paradox argues that if the universe is billions of years old, then there should be civilizations far more advanced than ours colonizing the galaxy; since we see no evidence of that, we must be alone (Webb, 2). Drake’s equation, while slightly more optimistic, still reduces the probability of communicating with other intelligent life to near zero: multiply the number of stars by…
