Interstellar Propulsion
There is no better way to learn about space then to actually go there. We can only discover so much from far off images and spectrometry techniques. This is why organizations like NASA and DARPA are trying to develop new methods of space travel to send us to other stars. There are a […]

Why Have They Not Visited?
The Drake Equation allows us to estimate the number of civilizations in our own Milky Way Galaxy. Even if conservative numbers are used for each of the factors in the equation, the equation yields a value in the hundreds or even thousands for the number of civilizations in the galaxy. With the numbers of galaxies […]

The Fermi Paradox
The galaxy is a pretty big place. With around 400 billion stars, it seems very likely that some of those stars have planets that can support life, that some of those planets have intelligent life, and maybe some of that intelligent life becomes space-faring. Even if we say the chance of a star having a […]

A Semester of Astronomy Class, A Year of Astronomy Photos
This video is a compilation of photos taken throughout 2012 from Chumack Observatories taken by astrophotographer John Chumack. Watching this video and seeing all of these photos really gives me a perspective on how much I’ve learned this semester. Before … Continue reading →

The Constant Search For Life
In this past week, three new planets have been discovered in Kepler’s habitable zone. These three planets are announced to potentially host life. This may or may not be true, but the thought of finding planets slightly larger than earth that are in the Goldilocks zone is exciting in itself. For me, this is what […]

UK Astrobiolgy Centre Searching For Life In Space
The UK atrobiology centre is seeking life outside of earth. The astrobiology field is still developing because we have not found any life forms of any kind outside of earth. But the UK centre is determined to succeed. They believe that Mars has a high probability of containing life. However, the surface of mars is […]

Space junk
After 60 years of sending things into space, the number of satellites, rocket stages, and pieces of debris floating around the Earth is gigantic. As that number continues to increase, the number of collisions between these objects is expected to increase too. We don’t think much about space junk. I guess we just hear about […]

Fermi Paradox
The Fermi Paradox is something I had thought about before even discovering that it had a name. If there is so much alien life out there, then why haven’t we […]

And It All Leads Up To The Now
This semester we have studied everything from the creation of the universe to black holes to microscopic bacteria living on the bottom of the ocean floor. The range of topics covered in this class has helped round my view of the beginnings of time up until now and clarified many common misconceptions ranging from tides […]
