Solstices/Equinoxes

Stone Henge Throughout a year on Earth, the sun changes positions in the sky due to the 23.4 degree angle of our axis. The points at which the sun reaches maximum and minimum heights in the sky are called the Summer and Winter solstices while the points half way between are called the Fall and […] Continue reading

The vast size and scale of the Universe

Cosmic Background Radiation Astronomy, Class, Uncategorized Today in this blog post I will describe the size and scale of the universe from my understanding. To start off, light from the sun takes approximately 8 minutes to reach Earth, yet light from the farthest parts of the observable universe would take 13.8 billion years. Keep in […] Continue reading

The Speed of Light In Respect to the Scale of the Universe

Distances in space is so great that it needs to be measured in how long it takes for light to travel to that location. Light travels around 299,792,458 m/s or about 671,000,000 mph. Compared to the speed of sound on Earth, which is about 373m/s or about 767 mph, the speed of light is more […] Continue reading

Blog 1: Cosmic Calendar and Biology

When we learned about the cosmic calendar in this class, I was immediately reminded of something I had learned two years ago in BSCI 1511 here at Vanderbilt, which was the biological timescale clock. I remember seeing this diagram and being really surprised by how recent humans, or even multicellular organisms, are in the history […] Continue reading

The Cosmic Calendar

For me, one of the biggest challenges in studying astronomy is truly understanding the scale of space and time. When humans have walked the earth for hundreds of thousands of years, it is hard to recognize that our collective existence is a mere flash in the grand scheme of the universe’s 14-billion year life. Every […] Continue reading

Waxing phases light on the right side of the […] Continue reading

The answer is that the moon is just a rock, not a glowing one, so all of the light we see is just reflected sunlight. Since […] Continue reading
