How Extremophiles Work

As we talked about in class a few weeks ago, Extremophiles are living things that flourish under challenging conditions.They are amazing because they can endure situations that would be fatal to the majority of other life forms. They originate from Archaea, Eubacteria, and Eukarya, the three branches of the three-domain categorization scheme. Extremophiles have caused […] Continue reading

The Fermi Paradox

A possible solution to the Fermi Paradox? The Fermi Paradox attempts to answer the question about extraterrestrial life that so many humans have thought about for centuries. Enrico Fermi a physicist, in 1950, while discussing extraterrestrial life he began to wonder if aliens did in fact exist then how have they not expanded throughout the […] Continue reading

Could We Even Communicate With Aliens If We Found Them?

After learning about the Golden Record, Arecibo message, and other ways astronomers have attempted to communicate with extraterrestrial life (if it is out there), I can’t help but think this outreach is very limited to civilizations that communicate in exactly the same way as we do. This seems unlikely to me, given the extreme diversity […] Continue reading

Where Are All the Aliens? Potential Solutions to the Fermi Paradox

In class, Dr. G mentioned a Wait But Why article about the Fermi Paradox. I absolutely love this article and the entire concept of the Fermi Paradox–I even wrote about it in my Common App essay four years ago! The Fermi Paradox, first informally presented by physicist Enrico Fermi, describes the apparent contradiction between our […] Continue reading

Post 7

The Fermi Paradox essentially states that given the size of the universe, there should be aliens. So where are they? This paradox is based on various estimation equations like the Drake and Seager equations, which are ways to estimate the number of other intelligent civilizations in the galaxy that should theoretically be able to contact […] Continue reading

JUICE Explorer

As discussed briefly in class, the European Space Agency (ESA) just successfully launched the Juice (formerly JUICE: JUpiter ICy moons Explorer) mission on April 14th! I had no idea this mission even existed before it was mentioned, so I decided to explore it further. The goal of this mission is focused on Jupiter’s moons. While […] Continue reading

The Statistics of Life

Artist interpretation of Kepler-452b, currently the most Earthlike planet discovered, which could potentially have an atmosphere and life Source: NASA Ames/JPL-Caltech/T. Pyle When faced with an effectively boundless universe, it inevitable to ask the question of how many other lifeforms are out there. In asking this question we tend to be a bit biased, looking […] Continue reading

Binary in the Pioneer Plaques

About the size of a license plate, the Pioneer plaques were placed on the Pioneer 10 and Pioneer 11 spacecrafts with the hopes of reaching intelligent extraterrestrial life. The two circles on the upper left of the plaque represent two hydrogen atoms, the most abundant element in the universe. If you look closely, the line […] Continue reading

Where is Everybody?

The Fermi paradox is a very simple question whose answer could have massive consequences for the future of humanity: where is everybody? With equations like the Drake equation predicting a huge number of extraterrestrial civilizations, it seems odd that we have detected no signs of life outside of Earth. In this blog post, I will […] Continue reading

Extremophiles: Life Finds a Way in the Most Extreme Places!

Extremophiles are organisms that can survive in extreme environments where other life forms cannot. These harsh environments can have high or low temperatures, extreme pressures, high levels of radiation, and/or extreme acidity or alkalinity. Despite the inhospitable conditions, extremophiles have developed unique adaptations that allow them to survive and thrive. Did you know that three […] Continue reading
