A recent study has found extremophiles in a location much more familiar to us, and it’s actually in the homes of humans. The study took samples from water heaters across all 50 states. Around 50% of the tested samples … Continue reading Are Extremophiles Our Roommates? Continue reading

A Brief, Incomplete History of “Earth”

When looking at our solar system, it is pretty easy to notice one thing that separates Earth from the other planets with which we share a star. Namely, Earth is the only planet not named after a Roman deity. You have Mercury, Venus, Mars, Jupiter, Saturn, Neptune, Uranus, and even Pluto! So where does “Earth” […] Continue reading

Climate Change

Climate change is predominantly caused by the greenhouse effect, which is when gases in our atmosphere prevent heat from the sun from escaping the Earth. As greenhouse gasses continue to be added to our atmosphere (primarily by burning fossil fuels), the greenhouse effect becomes more severe, allowing less and less heat to escape from our … Continue reading Climate Change Continue reading

Climate Change: Debunked

Contrary to popular belief, Earth’s climate has not always been the same; just in the last 650,000 years there has been several cycles of temperature rise and fall due to small changes in Earth’s orbit and the amount of energy Earth receives from the Sun. However, in the past 50 years, Earth’s climate has changed … Continue reading Climate Change: Debunked Continue reading

Cars and the Greenhouse Effect

Earth experiences a warming through the greenhouse effect: the absorption and re-emission of light from the planet’s surface by compounds in the atmosphere such as carbon dioxide and water. Greenhouse gases are necessary for keeping life on Earth warm enough to survive, but an increase in their concentration has led to a undesirable heating of … Continue reading Cars and the Greenhouse Effect Continue reading

Our Earth, the Spinning Top?

What if I told you that in a couple thousand years from now, your Zodiac sign would no longer be your Zodiac sign? It may be devastating to devout followers of astrology, but the relative positions of the Zodiac constellations are changing very, very slowly, at least from our viewpoint. This is due to a … Continue reading Our Earth, the Spinning Top? Continue reading

Measuring the Interior of the Earth

It is very hard to drill to the deepest part of the Earth. However, there are some indirect measurements that allow us to know limited information about the interior structure of the Earth. One of those is the measurement of seismic waves. By knowing the characteristic of seismic waves, we are able to identify the properties … Continue reading Measuring the Interior of the Earth Continue reading
