How Astronomical Are Our Chances of Finding Extraterrestrial Life?
I’ve always thought that we weren’t alone in the world–and my Astronomy class has really helped to confirm my thoughts. After studying the Drake Equation, it seems almost certain that intelligent life and life that could eventually communicate with us must exist. After all, the Earth is only 4.6 billion years old–a baby compared to […]

You Used to Call Me on Your Space Probe: Drake Equation
Personally, I love the Drake Equation. I think it’s extremely interesting to ponder, and it fascinates me that there are ways to roughly predict life within the Milky Way. However, I feel like the equation should be approached more so as a means to think about life rather than an actual mathematical equation. Rather than using […]

Contact: The Third Answer to Fermi’s Paradox
The Fermi paradox posits that there are only three possible answers to the question “Where is everybody?” in terms of the search for other intelligent life in the Universe. The three possibilities are as follows: We are alone Civilizations are common, but no one has colonized the galaxy There is a galactic civilization, but it …

(milky) way up, I feel blessed
This semester has been vital to understanding of the universe around me. Coming for Intro to Astronomy last semester, I felt that I had a pretty comprehensive basis upon which to build. What I didn’t realize coming in however was just how much more I was going to learn. The level of detail about not … Continue reading “(milky) way up, I feel blessed”

Drake Equation
One of the most interesting things that we have covered this semester is the Drake Equation. This equation uses probability to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy. What I like most about this … Continue reading →

Where is everyone?
This past couple weeks, we spent time looking in-depth at the Drake equation, a hypothetical equation that uses estimation to “calculate” how many communicating civilizations there likely should be within any one galaxy. Using accepted values for each variable within the Drake equation, this number is roughly 30 for one galaxy. That number multiplied by the […]

Blog 9 (The Unlikelihood of Intelligent Life)
Based on current scientific evidence, asteroids could have spread organic molecules to Earth and many other planets throughout the universe. In all likelihood, there are many organic molecules on most of the planets in the habitable zones of their galaxies, and it definitely seems possible that with all these organic molecules, some kind of primitive […]

The Drake Equation
The Drake Equation has been one of the most interesting things that I have learned about so far in this course. The video I have linked above does a very good job summarizing the different parts of the Drake Equation and how they are calculated. Towards the end of the video, it also talks … Continue reading The Drake Equation →
