Blog 0 Quick Introduction
Hello everyone, my name is Jadon Roy. This is a picture of me and my best friend who visited me in Nashville last semester. We are from Louisiana so it is always fun when he visits! This is my introductory blog for Astro 2110 Here is my blog https://wordpress.com/posts/jadonroyastronomy.wordpress.com Continue reading
Totality
On August 21, 2017, my family and I drove from Atlanta, Georgia to Clemson University in South Carolina to witness the solar eclipse in totality. Atlanta reached 97% totality, but Clemson reached complete totality: At about 2:37 PM, the moon completely covered the sun, positioning itself perfectly between earth and the sun and casting a […] Continue reading
Blog #1: Why is our neighborhood special?
But what about our place in the solar system makes life so conducive to earth? Why don’t we have cousins on Mars that we spend Thanksgiving with? Why doesn’t my uncle live on Venus? Continue reading
Blog 1:What Causes Seasons?
It is commonly believed that the Earth’s distance from the Sun determines the seasons. The Earth’s orbit is lopsided and we are closer to the sun at different times in the year. In the northern hemisphere, we are closest to the sun when we have winter debunking the misconception that the distance to the sun […] Continue reading
Total Solar Eclipse
On August 21st, 2017, the citizens of Oregon to South Carolina got to see a total Solar Eclipse. Although there is a total solar eclipse approximately every 18 months visible somewhere on Earth, the odds of the eclipse’s path passing over head where you can see it is much lower. Many mathematicians and scientist have […] Continue reading
Blog#1 Cosmic Calendar
I found the idea “Cosmic Calendar” particularly intriguing. Cosmic Calendar is a method to visualize the universe’s chronolUniverseling its currently understood age of 13.8 billion years to a single year (Therese). At this scale, there are 437.5 years per cosmic second, 1.575 million years per cosmic hour, and 37.8 million years per cosmic day (Therese). At this scale, on […] Continue reading
Precession Visualized
After reading the initial chapters of our textbook, I was captivated by the fact that the way Earth’s tilt changes can be dumbed down to the movement of a spinning top. It’s always fascinating seeing physics work on any scale, so I was eager to look into the subject. After a bit of searching, I […] Continue reading

Blog Post 1 Speed of Light and Light Time Travel
Ever since I was a kid I always thought about how time travel would work. However, no as an adult, I realize that the delay of light reaching our eyes is technically time travel. Every instance you see around you is actually one trillionth of a second in the past since it took light time […] Continue reading
Powers of Ten and the scale of the Universe
After reaching a scale of 10^24 meters, the camera zooms back in all the way to a single proton, which is visible and in frame at a scale of 10^-16 meters. 10^+16 meters is roughly 10 light years. With these two numbers, it also frames humans as obviously very large in comparison to a proton, …

Solstices and Equinoxes
The seasons change as Earth orbits the sun. Earth’s hemispheres receive different amounts of sunlight during each season because of the 23.5 degree tilt of Earth’s axis. When the Earth is at a point in its orbit that the northern hemisphere is tilted toward the sun, it is summer for the northern hemisphere. This is […] Continue reading
