As their name suggests, extremophiles are organisms that mostly dwell at the microscopic level and thrive in harsh conditions. Extremophiles can survive where other life cannot, and because they are so robust can endure even under the most stressful conditions. After learning about extremophiles in class, I wanted to research specific extremophiles found here on… Continue reading → Continue reading
Throughout the semester we have learned the ins and outs of many topics. We have learned topics ranging from the formation of atmospheres to the formation of solar systems. However, I feel that the topics that I have most benefitted from have been the ones that I can see every day. I love being able […] Continue reading → Continue reading
Spurred on by the Cold War, and aided by military research on ballistics and rocket fuel, NASA and the Soviet Space Program competed to complete more and more exceptional missions. In today’s less hostile international climate, the governments of the world are much less interested in space exploration than they once were. To continue the […] Continue reading → Continue reading
We have been learning a lot about extremophiles and whether they would be able to survive on other worlds, specifically within out solar system. I found an article on Wired that pointed to a discovery of microbes in a brine lake located beneath 65 feet of ice in Antarctica. This extremophile had to survive in […] Continue reading → Continue reading
Extremophiles are life forms that can tolerate extreme conditions. They are found in exotic environments all over Earth, such as deep sea vents, the upper atmosphere, and boiling hot geysers, such as those in Yellowstone National Park. Many astrobiologists believe that extremophiles represent the most likely type of life to exist on other planets. In […] Continue reading → Continue reading
The future of astronomy lies in finding or making worlds habitable for people. While we are learning so much about the universe around us, the things that people seem to care about are aliens and space colonization. This is why I feel that resuming space travel is crucial to reviving public interest in astronomy. While […] Continue reading → Continue reading
The field of astronomy is fascinating; there is much that we have yet to learn. This semester in Astro 201 …
Astronomy has taught me a lot of stuff about the universe that I didn’t know. What I will remember learning though is the size of our earth. Relative to our Sun, we are quite small. Relative to our solar system, we are barely visible, and relative to our galaxy, earth is nothing. The lesson is that […] Continue reading → Continue reading
The Fermi Paradox points out the issues with the expected number of predicted civilizations in the galaxy and the lack of interaction that mankind has had with them. It points out that the Sun is a young star and that many other star systems have had the time and conditions to bring about a civilization. […] Continue reading → Continue reading
