NASA’s Picture of the Day

For the class Astronomical Experiences assignment, I was going to write about NASA’s May 3rd, 2021 Astronomy Picture of the Day. As I went to search for the daily image, I also found a PBS Nova video on the Mars mission involving Perseverance and I was hooked. Now that I can blog about anything forContinue reading “NASA’s Picture of the Day” Continue reading

The Fermi Paradox

Ever since humans have first become interested in space, the inevitable question of “does life exist outside of Earth” has loomed over us. However, as technology has progressed and humanity has trekked deep into space, the question remains unanswered. This brings about a certain paradox regarding the existence of alien life. The universe is almostContinue reading “The Fermi Paradox” Continue reading

Radiometric Dating

Radiometric dating, or radioactive dating, is a method astronomers use to study a rock’s age. This method is critical in learning about the Solar System’s formation, as rocks from the Solar System can be studied to find how long ago the rock was formed and how old the Solar System is. When billions of atomsContinue reading “Radiometric Dating” Continue reading

Is the Moon actually made of cheese?

Unfortunately, the answer is no. However, the story of why the Moon’s surface looks the way it does it still an interesting one and one that helps us understand the solar system as a whole. The surface of the Moon most closely resembles that of Mercury (due to the lack of geological activity that comesContinue reading “Is the Moon actually made of cheese?” Continue reading

Tidal Friction: a 5 hour long day to a month long day

Due to the Universal law of gravitation, we know that objects of equal mass have a larger gravitation force between them when they are closer together. Because the near side of the Earth is closer to the Moon than the far side of the Earth, the force between the Moon and the near side ofContinue reading “Tidal Friction: a 5 hour long day to a month long day” Continue reading

The Cosmic Calendar

Definition: a calendar in which the 14-billion-years of the universe’s existence, from the time of the Big Bang until this moment, are scaled to a period of one year. Origin: The idea of the Cosmic Calendar was first described by astronomer Carl Sagan on the original version of the television show Cosmos in 1980. KeyContinue reading “The Cosmic Calendar” 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

Muons and Time Dilation

In my opinion, one of the coolest parts of astronomy is relativity, the theory describing the warping of spacetime.  If you’ve ever seen Interstellar, you’ve been exposed to one part of the theory: time dilation.  In short, time dilation is a phenomenon that causes time to pass more slowly in one place than another (relativeContinue reading “Muons and Time Dilation” Continue reading

Eclipses and History

A seemingly everlasting problem historians run in to are exact dates. Since each ancient civilization had their own calendar and their own way of measuring time, it’s a challenge for historians to connect the dots between civilizations and produce an accurate timeline of human history on the Earth. However, historians have discovered the common denominatorContinue reading “Eclipses and History” Continue reading

Leap 🐸 Year

I can’t be the only one that questioned why we would get an extra day and the Olympics every four years when I was younger. While this isn’t the time to discuss the Olympic schedule, this did provide me with a chance to discover the real reason February 29th pops up every four years. AsContinue reading “Leap 🐸 Year” Continue reading
