Several Jovian moons are candidates for extraterrestrial life. One of these is Enceladus, a medium-sized moon of Saturn. Like Europa, there is strong evidence for a subsurface ocean, which is likely 30-40 kilometers below the moon’s surface, and then extends down another 30 kilometers. Due to the suspected ocean’s thickness, it is more likely that […]Read more "Blog 8 – Life on Enceladus?"
From the title, you might think the subject of this blog is about human space travel, something that isn’t very developed today. However, it is possible that some life forms before us have experienced travel between the planets. There are theories that support the idea that life originated on either Venus or Mars, and then […]Read more "Blog 7 – Interplanetary Life Travel"
Among the most asked questions regarding space are ‘is there intelligent life outside of Earth’ and ‘is our solar system unique’? So far, science has not found a planetary system quite like our own. This makes one wonder if our existence is rare or even unique, or if not enough data been found to make […]Read more "Blog 6 – Is the Solar System Unique?"
Comets are the relatively small, icy objects that orbit a star. They are classified as “small solar system bodies”, as are asteroids. Along with ice, they contain rocky dust and other complex chemicals, leading them to be described as “dirty snowballs.” Spectra can be used to determine the composition of comets. From them, we know […]Read more "Blog 5 – Comet Composition"
For this blog I thought I’d write about how sunspots affect the Earth’s climate, as I am studying environmental sciences and I recently took Professor Gilligan’s Global Climate Change course (highly recommended and it counts for AXLE). Sunspots are the most interesting feature on the sun’s surface. They are the dark patches that periodically appear […]Read more "Blog 4 – The Sunspot Cycle and Earth’s Climate"
For this blog I thought I would further look into the electromagnetic spectrum. As in the picture below, we can see that the light that humans see is only a small portion of the full spectrum of light, collectively known as the electromagnetic spectrum. Light itself is technically radiation, but only certain types of light […]Read more "Blog 3 – Electromagnetic Spectrum"
For my second blog, I thought I’d discuss the idea of simplicity in astronomy; specifically, the idea of Occam’s Razor. One of the hallmarks of science is the progression of creation and testing of models of nature that explain scientific observations as simply as possible. This idea, that scientists should prefer the simpler of two […]Read more "Blog 2 – Occam’s Razor"
