Speed of light in Space

Posted on January 22, 2024 by Andres Becerra

Picture by: FlashMovie/Shutterstock Light moves pretty fast. It actually moves the FASTEST out of anything that we know of (for now). Light moves at about 300,000 kilometers per second. When I’m in a rush on the freeway, I drive up to 145 kilometers per hour (90 miles per hour) which is only 0.04 kilometers a […] Continue reading →

The Speed of Light/Light Travel Time – Cameron Klein

Posted on January 21, 2024 by Cameron Klein

Before beginning this course, I was familiar with the term light-year, but not in the way that it is truly meant to be used. When talking to members of my family, it is a common expression for us to say, “It’s going to take me lightyears to clean my room!” or “Doing my laundry is […] Continue reading →

The Evolution of the Universe from the Big Bang to Modern Day Humans     When I first started this course, I knew that our universe was very old, however, I didn’t understand the depth to how long it really was. Our universe has evolved significantly from the original Big Bang that occurred approximately 14 billion […] Continue reading →

If you’d like to feel the crushing weight of existential dread as we approach the end of this course, and for me, the end of my time at Vanderbilt, I have just the video for you! It’s a YouTube video called “Age of Universe: Time in Perspective,” and it uses a time-to-volume comparison in order […] Continue reading →

Blog 8 – The History of Venus

Posted on April 26, 2023 by Melanie Marszal

When asked to picture Venus, many of us picture a hot, volcanic, inhabitable place — and we would be correct. However, science suggests that it may not have always been this way. A study of five different climate simulations of Venus found that in each of these scenarios, the planet could have supported liquid water […] Continue reading →

The Cosmic Microwave Background

Posted on April 9, 2023 by constellationsarentreal

One of the pillars that the Big Bang Theory Model rests on is the existence and characteristics of the Cosmic Microwave Background (CMB). The CMB is an observed cosmic glow of radiation seen everywhere, filling the universe like a sea. Roughly 380,000 years after the Big Bang, the universe cooled enough (~3,000K) for free-roaming electrons […] Continue reading →

Time Dilation and the Theory of Relativity

Posted on March 7, 2023 by Europa

With our totally unrestricted guidelines on Blog 4, I would like to make a bit of a deviation from the content of our course and discuss time dilation and the theory of relativity! When I first learned about time dilation, which refers to the difference in elapsed time as measured by different clocks due to […] Continue reading →

What will happen to our solar system when we collide with Andromeda?

Posted on February 28, 2023 by Melanie Marszal

You may be familiar with Andromeda, our closest neighboring galaxy. You may have also heard that Andromeda and our Milky Way are moving towards each other. But what will happen to Earth and the rest of our solar system when these two galaxies collide? Will Earth even still be around by then? The answer to […] Continue reading →

Astronomy is a science. This means that in astronomy we make predictions, test hypotheses, and use findings to continuously build and refine our theories. Interestingly, astronomy was very likely the first science. Humans, ever since the ancient civilizations, have looked to the sky and pondered its mysteries. What use would such people have in astronomical […] Continue reading →

Ancient Egypt Switches from the 360 to 365-Day Year

Posted on February 6, 2023 by Europa

The other day, my friend told me about an Ancient Egyptian myth regarding the switch from the 360 to the 365-day calendar in Egypt. At the time, I just thought it was a cool story, but later realized that it was a perfect example of archaeoastronomy. Before 4200 BCE, the Ancient Egyptian calendar year was […] Continue reading →
