Space Travel I am still trying to decide whether my admiration for Elon Musk is because of his electric vehicles (S-3-X-Y) or his passion for space exploration. The topic of space exploration leads me to a scientific field I would like to talk about briefly, Astrobiology. Wikipedia defines Astrobiology as “an interdisciplinary scientific field concerned … Continue reading Astrobiology, The Future. → Continue reading → Continue reading
This was a great class, and I’m grateful for all the information I learned. Some concepts were reemphasized since I knew them before taking the course, but I’ve received and retained some new, useful knowledge that I can share with others. I’ve been interested in all things concerning astronomy since I was young, and I … Continue reading A Great Semester → Continue reading → Continue reading
Is liquid water necessary for life to form? If judging strictly from the only life we know, of course. However, humanity’s exploration of the universe has just begun, and we can’t say for sure what lies beyond Earth. Other worlds within our solar system have organic compounds that life could possibly evolve from. In particular, … Continue reading Methane-Based Life → Continue reading → Continue reading
The Ancient Egyptians cared a great deal about astronomy. Probably too much, in fact. According to their beliefs, the movements of the planets and stars played a role in the annual flooding of the Nile river, and if you are an Ancient Egyptian, you will do just about anything to appease the Nile, and that … Continue reading Ancient Egyptian Astronomy → Continue reading → Continue reading
Astrobiology is becoming an increasingly discussed topic as new exoplanets are being found and we discover more about the worlds of our own solar system. Of course, for there to be life on other planets, it first needs to come into existence on its own through abiogenesis, or the creation of life through non-biological sources. … Continue reading Hydrothermal Vents: The Origin of Life? → Continue reading → Continue reading
I learned much more than I thought I would in this course. Before taking this class, all I really knew about our solar system was that there are 8 planets (and Earth is the third one), the asteroid belt is a thing, Jupiter is big, and Saturn is the planet with pretty rings. I didn’t … Continue reading Finale – Culminate Post → Continue reading → Continue reading
I was inspired by Victoria’s post to think more about the Fermi Paradox, and specifically, explanations of the uniqueness of intelligent life on Earth. The Rare Earth Hypothesis is one such explanation; it postulates that conditions favorable to life (and particularly intelligent life) are incredibly rare in the universe. It is in opposition to hypotheses […] Continue reading → Continue reading
Discovered in 1970, Archaea might be the least well-known of the three domains of life (the others being Bacteria and Eukaryota), but it is a fascinating and diverse group of organisms and quite possibly the first on Earth. Like bacteria, archaea are unicellular, prokaryotic organisms, meaning that they lack nuclei and other membrane-bound organelles in […] Continue reading → Continue reading
An amazing part of the class this semester was the ability to understand and correct some of the misconceptions that I have held about the Solar System for years. Whether it was about the ‘dark’ side of the moon, the brightness of the North Star, tides, the asteroid belt being hard to navigate through, or … Continue reading I See the Light → Continue reading → Continue reading
One of the world’s most fascinating and natural wonders are the Northern Lights. These magical lights come in a variety of dancing colors. This seemingly random light show occurs as a result of interactions of Earth’s magnetic field and atmosphere with solar winds. Solar winds released by the Sun’s sunspot regions travel through space until … Continue reading The Northern Lights → Continue reading → Continue reading
