High and Low Tides with a Bit of British Humor
High and low tides can pose great challenges and dangers to nature lovers, especially those who enjoy being close to the water. I was originally searching how spring/neap and high/low tides might affect erosion rates; while scouring the Internet, I found this article from the UK (Lancaster Guardian) that details how these tide patterns actually […] Continue reading
How Do Moons Form?
Have you ever considered how Earth got its moon in the first place? Astronomers have come up with several theories for why each planet in our solar system has a certain number of moons, and how these moons formed. For Earth’s moon, it is thought a collision with another planet shortly after formation of the […] Continue reading
archaeoastronomy
Astronomy hasn’t always been practiced the way that it is today! For many centuries, different civilizations have conceptualized the universe in a wide range of ways covering the entire spectrums of science and mythology– from this, at the intersection of astronomy and anthropology, the field of archaeoastronomy was born! The field began with the discovery […] Continue reading
Retrogrades
Have you ever thought about why planets in our night sky sometimes appear to be moving backwards? Well, this phenomenon is known as retrograde motion. It is not as strange as it sounds. Retrograde occurs when a planet is moving in the sky and appears to be moving backwards from our perspective on Earth – […] Continue reading
Ancient Egypt Switches from the 360 to 365-Day Year
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

NASA’s James Webb Telescope was launched on December 25, 2021. It is a collaborative effort between NASA (United States), The European Space Agency, and the Canadian Space Agency. This telescope has four main areas where its data will be used: considering the first light in the universe, early assembly of galaxies in the universe, birth […] Continue reading

How Tides Actually Work
When I was younger, I thought that mermaids were the reason why the tides moved. I thought that mermaids were pulling the ocean back and forth. I later learned the actual origins of the tides in school, but I would still like to think that mermaids were the reason. Instead of mermaids, tides are actually…Continue reading » Continue reading
How the Moon Affects the Earth’s Tides
It is a common misconception that the tides on Earth are caused because the Moon’s gravitational pull is just pulling the ocean towards it. However, if this were the case then there would only be one tidal change every day…
Gyroscopes in Space – Angular momentum
In this 2016 demonstration aboard the ISS, the ESA astronaut Tim Peake demonstrates how a gyroscope spinning in space maintains its orientation even when a rotational force is applied. While, this video was published in 2016, the physics of rotation have not changed since then! In the video, Peake demonstrates how once a gyroscope gets […] Continue reading
Historical Vanderbilt Astronomer
If you have spent much time in E. Bronson Ingram residential college on Vanderbilt’s campus, you may have noticed that part of the dorm is named after one Edward Emerson Barnard. As it turns out, Barnard was an astronomer who attended the university from 1883-1887. His research focused on observation and photography of stars and […] Continue reading
