What are exomoons? Well, we have already studied exoplanets (short for extra-solar planets) which are planets that are not from our star system. Accordingly, exo-moons are moons that orbit planets that orbit stars that aren’t the Sun. Sounds pretty cool, right? Well exomoons get even more interesting. In fact, exomoons are currently the subject of…
One of the more peculiar parts of our universe is the presence of a great deal of mass that we cannot see. When looking at the gravitational effects on the mass in the universe, it is apparent that a significant amount of matter must be present but is not visible to us, leading to its … Continue reading Dark Matter and Dark Energy → Continue reading → Continue reading

If my short study of Astronomy has taught one thing, it is how influential Astronomy has been on our way of thinking as a species. This influence can be seen in ancient times, when civilizations such as in Mesopotamia, Mesoamerica, Egypt, China, India, and Greece placed Astronomy and Astrology at the centers of their ideology, […] Continue reading → Continue reading

Over the course of the semester, I learned a lot of things. I started off learning about the size and scale of the universe, and the enormous distances between planets and stars. We can’t even travel a tenth of a light year in our lifetime in the fastest spaceship we own. Our furthest spacecraft, Voyager … Continue reading Pale Blue Dot → Continue reading → Continue reading
Given that NASA is a government agency, it’s a little worrisome how it’s funding can be pretty wantonly taken and given as the government sees fit. (That’s why privatization of the space industry through companies like Elon Musk’s SpaceX is so necessary) However, Nasa is currently budgeted .5% of our national budget- that’s 18.4 billion-so […] Continue reading → Continue reading
