Where are they?

The likelihood of life outside of our planet is a heavily debated topic.  Overall, it seems reasonable to assume that with all of the unexplored universe around us, and the conditions required to sustain life that are not all that hard to find, there should be plenty examples of life elsewhere.  Despite this, and the overwhelming beliefContinue reading “Where are they?” Continue reading

The Fermi Paradox

The Fermi Paradox is a baffling observation about the galaxy and extraterrestrial life. The paradox asks, given all of the plausible explanations and arguments for the abundance of life in the universe, why haven’t we encountered signs of such life yet? With a self-replicating automatons and “modest amount of rocket power and an immodest desireContinue reading “The Fermi Paradox” Continue reading

The Fermi Paradox and Great Filters

We briefly discussed the Fermi Paradox in class. However, one major potential “explanation” of the paradox went undiscussed: the idea of various “great filters.” These great filters are supposedly things that naturally arise in the course of life’s and/or civilization’s development that prevent them from becoming long-lasting intelligent life forms. These could be a wideContinue reading “The Fermi Paradox and Great Filters” Continue reading

Aliens in Pop Culture

Picture an alien. What did you think it looked like? Maybe you thought of a small green creature with a big head and big eyes, or maybe you thought of ET or one of the people from Avatar or Jar Jar Binks. No matter what you thought of, your picture was likely influenced by popContinue reading “Aliens in Pop Culture” Continue reading

A New Hope (For Alien Life)

Astronomy 2110 has been a real pleasure of a class to attend. Not only have I learned so much about Earth, but also about the rest of the solar system. I have discovered the secrets of our planet, the planets that are our neighbors, and our incredible star that I would have never known ifContinue reading “A New Hope (For Alien Life)” Continue reading

The Fermi Paradox

If you were to ask different people what one of their biggest questions about our universe is, it’s pretty believable to think that one of the most common questions would be “Do aliens exist?”. This question is especially important in that it’s a question that no one really knows the answer to; whether or notContinue reading “The Fermi Paradox” Continue reading

Extraterrestrial Existence

Shouldn’t Earth have been visited by extraterrestrials already? Enrico Fermi, a physicist from Italy, asked the same question in 1950 and sparked a wonderful conversation in the field of astronomy and astrobiology. In 1975, Michael Hart published “An Explanation for the Absence of Extraterrestrials on Earth,” noting that the lack of intelligent life from the … Continue reading Extraterrestrial Existence Continue reading

Life on Europa?

There is life in all forms throughout the world. Even in the most remote places with the most extreme conditions we have seen life not only survive but thrive. This makes us wonder, could there be life on possible habitable worlds? NASA put this to the test by conducting an infrared (IR) signature of oneContinue reading “Life on Europa?” Continue reading

May the 4th be with you: the Twin Suns of Tatooine

One of my recent blogs crushed the dreams of many Star Wars fans by debunking the close proximity of asteroids within an asteroid field in The Empire Strikes Back. That is why, in the spirit of Star Wars Day, I will be sharing an aspect of the films that Star Wars ended up getting correct:Continue reading “May the 4th be with you: the Twin Suns of Tatooine” Continue reading

The Fermi Paradox

The age-old question of whether life exists on other planets in the Solar System is one that may not be solved for centuries. Frank Drake and Sara Seager spent years developing their respective equations (shown below) that can be used to predict the probability of aliens existence, but the concept of life outside of EarthContinue reading “The Fermi Paradox” Continue reading
