Monster from the Deep

Extremophiles are definitely some of the most persistent living beings. These microorganisms are able to survive in conditions regarding temperature, acidity, and/or chemical concentration beyond extreme that would prove fatal to almost all carbon-based life on Earth. While many extremophiles prove to look nightmarish, one type of extremophiles might give the others a run forContinue reading “Monster from the Deep” Continue reading

Historical Astronomers in Context

Johannes Kepler Johannes Kepler, a German astronomer, was important to our history for discovering three laws of planetary motion that are now named after him as well as finding key evidence for the highly-debated Sun-centered idea. Kepler’s first law explained that each planet orbits the Sun following an elliptical path with the Sun as aContinue reading “Historical Astronomers in Context” Continue reading

Our Entire Universe in One Year

Imagine if we were able to fit the history of our entire universe—from the Big Bang all the way up to today—into a single calendar year. That would be crazy right? Well look no further because that’s exactly what the Cosmic Calendar is. Created and popularized by Carl Sagan, the cosmic calendar compresses 14 billionContinue reading “Our Entire Universe in One Year” Continue reading
