Escape Velocity and Space Exploration

In our generation, space exploration has been an extremely valuable way to learn more about our solar system and our galaxy, the Milky Way. It is astounding that humans have been able to set foot on the moon, and that astronomical research centers have sent probes to a variety of astronomical objects within our galaxy, […] Continue reading

some final thoughts

When I started this class, I didn’t expect to find so many connections between astronomy and they other subjects I’m interested in! I am majoring in philosophy and political science, subjects that I believed to be totally independent from the physics and history of our universe. Thankfully, I was very wrong! I still am shocked […] Continue reading

the fermi paradox

Sir Arthur C. Clarke, a British science fiction author, said that “two possibilities exist: either we are alone in the universe or we are not. Both are equally terrifying”. And he was exactly right! The more that we learn about and explore the universe, the more we learn about the possibility of life out there, […] Continue reading

aurorae

The shimmering curtains of color that make up the Northern Lights are incredibly fascinating. For many (myself included), it is a life goal to get to witness this phenomenon in person. The name Aurora Borealis has its roots in classical mythology. Famous astronomer Galileo Galilei combined the Roman goddess of the dawn, Aurora, with the […] Continue reading

comets

The terms ‘asteroid’ and ‘comet’ are often used interchangeably, but in reality there are important differences between the two! The primary difference is in their composition; asteroids are rocky because they formed in the inner Solar System, and comets are more icy because they formed beyond the frost line! Comets are visible every few years […] Continue reading

nuclear fusion

Have you ever wondered why the sun shines? It’s a question that has inspired centuries of astronomers to come up with a wide variety of explanations. It was once thought that the sun shone because of chemical combustion, but we now know that there is nowhere near enough oxygen for that process to have sustained […] Continue reading

climate change

It’s no secret that our planet is in the midst of a global climate crisis– rising sea levels, compounding greenhouse gas emissions, and depleting natural resources have left our environment at a very real risk of collapse, endangering all living creatures on our planet. When studying astronomy, it becomes easy to lose focus on the […] 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

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
