The Fermi Paradox

Posted on December 5, 2024 by Elias Ibrahim

outer space The physicist Enrico Fermi once asked the question “Where is everyone?” on the topic of extra terrestial life. The Fermi Paradox comes from the idea that if the universe is so old and vast why haven’t we found clear evidence of life elsewhere in the universe. When this thought is taken further it […] Continue reading →

Astronomy Reflection

Posted on December 5, 2024 by Alekzander Waller

Picture Source What have you learned from this course that surprised you the most?Why did it surprise you? The part of this course that surprised me the most was everything relating to spectroscopy. I was very intrigued that astronomers could figure out all of this information about a planet just from what is emitted (or […] Continue reading →

Final Post

Posted on December 5, 2024 by Michael

I think the most surprising thing this course has taught me is just how different the different planets in our solar system are. Prior to this, I would have guessed that the planets and objects in our solar system are pretty similar in both current characteristics and formation. But I was surprised to find out […] Continue reading →

Tardigrades and extraterrestrial life

Posted on December 5, 2024 by Michael

I first saw a picture of a tardigrade when I was a child, and even then, I was fascinated. I prefer the more affectionate term “water bear”, and these cute little “micro-animals” are a classic example of just how resilient life can be. As we briefly discussed in class, tardigrades have survived exposure to outer […] Continue reading →

a. I was most surprised by how much we can discover about celestial bodies from our long distances. In the cases of other stellar systems, we may not know so much, but within our own, we’re able to study other bodies and make deductions about their properties to such a granular level– and this was […] Continue reading →

The Fermi Paradox Explained

Posted on December 5, 2024 by Alekzander Waller

Source The Fermi Paradox describes the contradiction between high and low probability of extraterrestrial civilizations that exist in the universe and the lack of evidence for, or contact with, such civilizations. The term is named after the physicist Enrico Fermi who asked “Where is everybody?” during a conversation about the likelihood of alien life in […] Continue reading →

What are the Odds?

Posted on December 5, 2024 by Leo Silva

The Drake Equation is a formula proposed to estimate the number of technologically advanced civilizations within a given galaxy that may be capable of communicating with us. It doesn’t calculate anything with certainty but, instead, aims to stipulate that if we give X, Y, Z, criteria, what would we expect to see? How many civilizations […] Continue reading →

Image from Cosmos Magazine Extremophiles are organisms capable of living under extreme conditions. This includes but is not limited to extreme temperature, radiation, pressure, and pH level. Given the extremely resilient nature of these organisms, they are some of the most abundant life forms. These creatures are fascinating as they have helped to stretch our […] Continue reading →
