Blog 8 – Evidence for a Europan Ocean

Europa, Jupiter’s 4th largest and 2nd closest Galilean moon, is thought to have a large saltwater ocean covered by a layer of ice. An article from Nasa details the evidence for the existence of this ocean. The first piece of evidence is the matching zig-zagging cracks on the surface that indicate that the surface was […] Continue reading

Blog 7 – The Dark Forest Solution to Fermi’s Paradox

Fermi’s paradox is that based on the number of stars in our galaxy and estimates on the likelihood of intelligent, space-faring civilizations to develop in a star system, we should expect to see some signs of alien life in our galaxy. Some possible solutions to the paradox are that Life is more rare than we […] Continue reading

When the Sun Dies

All good things must come to an end, including the ancient (at least relative to humanity), life-giving star we see each day. Even though the sun is considered a young star, it still has a finite lifetime, and it will eventually “die” in about 5 billion years. The image above shows a rough timeline of […] Continue reading

blog post 08

This class opened my eyes to some really cool astronomy subjects. Astronomy is a subject that I never really got the chance to study in grade school. Since coming to college, and learning more about our universe, my perspective on life has changed. Learning about how vast our universe is, how our solar system formed, […] Continue reading

SolSys2110 – Culminating Post

Over the course of four months, I have learned not just about our solar system, the Milky Way, and the universe at large, but also about the process of science, the history of astronomy, and humanity’s never ending (and really just beginning) quest to find companionship in the cosmos. Before I took this course, I […] Continue reading

blog post 07

The Fermi Paradox is the conflict between the lack of evidence of extraterrestrial life and high estimates for its existence. The main explanation people have come up with for this paradox is that intelligent life is rare. Using this explanation, it makes sense why there would be many places with rudimentary life, but without intelligent […] Continue reading

My newfound view of Astronomy and our Solar System

Throughout this semester, I have learned so many new and fascinating things about our solar system and astronomy as a whole. Whether it be learning more about the fathers of Astronomy such as Copernicus or Galileo or mind-boggling concepts such as gravity, I now understand that I have only scratched the surface of understanding the […] Continue reading

Blog 7:Fermi Paradox

The Fermi paradox is the conflict between the lack of evidence for extraterrestrials and the high estimates for their existence . The name came from the Italian-American Physicist Enrico Fermi. He was roughly quoted as saying “Where is everybody?” This paradox has been explained by saying that the number of intelligent civilizations is very low. […] Continue reading

Tardigrades… and what humans can learn from them

Tardigrades are one of the most adaptable lifeforms in existence. The tardigrade is classified as an extremophile, or one who can live in extreme conditions, because of its ability to enter cryptobiosis. Cryptobiosis is a condition that results from slowing down an organisms metabolic and reproductive processes to almost a complete halt. The closest state […] Continue reading

Astrobiology

Astrobiology is such a fascinating subject because some people may not even believe there is a need for this subject in the first place. This is because astrobiology is the study of life found throughout the universe. When the argument is presented that there is no life found outside of the Earth, my first thought […] Continue reading
