The origins of life and the Drake equation
In using the Drake equation to discuss and estimate the probability of non-Earth life in our universe, one factor we estimated was the probability of life developing on a given planet in the habitable zone. The problem with making such an estimate as students in an Astronomy 201 course, of course, is that we all…

Are We Alone?
The famous science fiction writer Arthur C. Clarke was quoted as saying, “Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.” A truer statement is hard to come by. Yet quote also sparks tremendous debate and intrigue among those whose ears come across it for the … Continue reading Are We Alone? →

Impacts on Saturn and the Drake equation
NASA’s Cassini spacecraft recently observed meteors colliding with Saturn’s thin rings. This marked the first direct evidence of small meteoroids breaking into streams of rubble and crashing into Saturn’s rings, although astronomers already expected this to be occurring regularly. However, specific details of such impacts were merely speculation, much of which is cleared up via […]

The Drake Equation – A Scientific Shot in the Dark
The Drake Equation is an incredibly interesting topic of discussion. Obviously, determining the number of communicating civilizations in our galaxy is a monumental task. Because of the sheer size of the problem, the fact that a simple equation can bring us anywhere close to a reasonable guess is in itself very impressive. As impressive as […]

3 Prime Locations for Life
Scientists recently announced that Kepler has found 3 exoplanets that are our best bet for finding life outside the solar system. These three planets – Kepler62e, Kepler 62f, and Kepler 69c – are the smallest to be discovered within the habitable zone, meaning that liquid water could potentially exist on any or all of them. And […]
