solar system superlatives: Earth
Welcome to the last episode of solar system superlatives. I know it’s hard to believe, but, alas, all good things must end. In an effort to dry the tears brimming in all our eyes, I wanted to end this blog series on a happy note and on a celebration of vitality – by looking atContinue reading “solar system superlatives: Earth” Continue reading
ExploreVenus
In astrology, ruling planets are the specifically designated planet for each of the zodiacs. Since there are 12 zodiac signs and only 7 planets, some share the same planet such as Libra and Taurus who are both ruled by the planet Venus. Each planet is said to have a distinct energy that affect us atContinue reading “ExploreVenus” Continue reading
Conan the Bacterium, a potential Martian?
Conan the Bacterium, also known as Dionococcus Radiodurans Evolution, as far as we know, has always been pushing the limits of adaptability, allowing organisms to survive in the harshest of environments. Life that is extremely adaptable to almost all living environments are called extremophiles, hence their name. Scientists have recently hypothesized that some of Earth’sContinue reading “Conan the Bacterium, a potential Martian?” Continue reading

Explore Giants
Earth may seem special to us, but it is just one of a near countless number of planets in our universe—a rather small one at that. Giant planets are those planets that dwarf Earth in size. They are gaseous bodies, meaning that they are primarily composed out of a swirling combination of gasses held togetherContinue reading “Explore Giants” Continue reading

Mercury’s Shrinkage
It’s been long thought that of the Fab (Terrestrial) Five, only Earth remains geologically active. However, recent evidence shows that little Mercury, long thought to be tectonically dead, is actually shrinking! The evidence comes in the form of small troughs (upper arrows in the picture below) and scarps (lower arrows) astronomers were able to photographContinue reading “Mercury’s Shrinkage” Continue reading
What’s in Charge of Earth’s Long-Term Climate Change?
Climate change has been worsening, so much so that when news outlets report on it the term sounds like just another buzzword. Current projections of the United States’ future coastlines don’t look at all forgiving. Where did this catastrophe start? Well, to answer that question we have to examine four key factors: solar brightening, changesContinue reading “What’s in Charge of Earth’s Long-Term Climate Change?” Continue reading

The Formation and Evolution of our Atmosphere
Us residents of the Earth take our atmosphere for granted. We constantly bombard it with harmful chemicals and pollute it with manmade substances that can permanently damage our “forcefield” around Earth. After all, it is responsible from keeping us safe against the harmful rays of the sun and provides us with the oxygen we needContinue reading “The Formation and Evolution of our Atmosphere” Continue reading

Survival Sweet Spot
Earth is a perfect amalgamation of all the conditions necessary for live to thrive. I always hear that the other terrestrials cannot sustain life, but never exactly sure how unsuitable they were. I mean if there was only one thing wrong with them, who’s to say we wouldn’t be able to invent a solution inContinue reading “Survival Sweet Spot” Continue reading
Mars, Water trapped in Rocks
An Artist’s Rendition of what Mars may have looked like 4 billion years ago As we have discussed in class, Mars looks very different today than it did billions of years ago. One notable difference is that Mars may have liquid water, as we see evidence of this in canyons and dried river beds inContinue reading “Mars, Water trapped in Rocks” Continue reading
