The Fermi Paradox

Have you ever sat around and wondered, where are all the aliens? Well, you certainly aren’t the only one. In 1950, Enrico Fermi came to the realization that “any civilization with a modest amount of rocket technology and an immodest amount of imperial incentive could rapidly colonize the entire galaxy” according to SETI.  His theory, known… More The Fermi Paradox Continue reading

Out of this World Symbols

Astronomers, like all scientists, love their symbols. Why spend ages written out full text when shorthand will do? Not only  are the symbols for the planets convenient, they also have interesting stories behind them that tie into the planet’s history. Sun: The symbol for the sun is a circular shield with a dot in the […] Continue reading

The Effect of Living in Space

While I think that studying space and astronomy is super awesome, I honestly am not sure I can imagine anything worse than living in space for an extended period of time. As we discussed in class, living in space (or at least in orbit) is essentially like being in constant free fall. You know that stomach […] Continue reading

Project Orion: Riding Atomic Explosions into Space

From the LSD-laden project MK Ultra to the ill-fated foray into psychic warfare that was Stargate Project, the U.S. government has sanctioned some truly strange studies over the past century. But one research endeavor stands out among all the others throught its sheer magnitude, ridiculousness, and surprising potential. I am talking, of course, about Project Orion. […] Continue reading

The Sun’s Absorption Spectrum

Absorption spectra occur when a hot solid or liquid or very dense gas give off a continuous spectrum, with all colors, and then that continuous light moves through a thin gas that is cooler than the source of the continuous light. This thin gas absorbs some of the light being given off by the source […] Continue reading

The Solar System’s Symphony

Its common knowledge that space is a vacuum, and that sound can not be heard inside of a vacuum. However, this is not technically true.  The solar system is constantly pulsating and producing electromagnetic waves. While these electromagnetic waves go undetected by human ears, our friends at NASA have created a special tool that uses […] Continue reading

One Shift, Two Shift, Redshift, Blueshift

Images: Redshifted, blueshifted spectra,   The Doppler shift You’re probably already familiar with the doppler effect of sound. Every time you hear a car zoom past, it pitch changes from higher as it approaches to lower as it leaves. This is because sound is dependent on the relative position of the observer, and if the sound […] Continue reading
