Blog 2: Tides
Tides represent the ebb and flow of ocean waters, orchestrated by the gravitational influences of both the moon and, to a lesser degree, the sun. As the moon orbits the Earth, its gravitational force interacts with our planet. Despite the moon’s relatively small mass, its gravitational pull, although not immense, varies across the Earth’s surface […] Continue reading
Historical Astronomers in Context
Johhanes Kepler was important to astronomy for many reasons, the major reason was for his 3 laws of planetary motion. One of them was that the planets orbit elliptical around the sun. Another is the square of the orbital period of a planet being proportional to the cube of the semi-major axis of orbit. (Link) […] Continue reading

Nicolaus Copernicus Born: February 19th, 1472 Died: May 24th, 1543 Image by: Britannica Nicholas Copernicus was important in astronomy because he opposed the idea that everything revolves around the Earth. He argued that we and all other planets revolved around the sun, not the Earth. He also believed that the orbits of each of the […] Continue reading

Brittanica Johannes Kepler: December 27, 1571 – November 15, 1630– Kepler was originally hired by Tycho Brahe to do many calculations because brahe was not a profound mathematician. After Tycho’s death, Kepler was able to secure some of his formerly privatized data and observations to develop what would become known as Kepler’s Laws of Planetary […] Continue reading
The Speed of Light
In 1905, Albert Einstein took the first crack at the Newtonian foundational physics. In his paper on special relativity, Albert Einstein postulated that the speed of light, c, is constant in all inertial reference frames. Assume that a person on a bicycle is holding a flashlight and moving at a constant speed relative to someone […] Continue reading

Blog 1: Our Expanding Universe
Our expanding universe is a captivating cosmic phenomenon that continues to unfold in the vastness of space. Galaxies throughout the cosmos are in a state of expansion, distancing themselves from one another as space itself expands between them. From our vantage point on Earth, nearly every galaxy beyond our Local Cluster is gradually moving away […] Continue reading
Blog Post 8: How astro2110 Has Changed My View On Astronomy
Before coming into astro2110, I knew very little about astronomy. Now, after completing the course, my appreciation for astronomy has greatly increased. A few days before the semester started, one of my friends who is an astronomy nerd laughed at me for not knowing the phases of the Moon. I thought to myself, “I’m a […] Continue reading
Godzilla the Extremophile
(Diagram of the various conditions in which different types of extremophiles live) Extremophiles are organisms that live in, you guessed it, “extreme” environments, like volcanoes, the bottom of the ocean, acidic areas, etc. When we talked about extremophiles in class, we mostly looked at microbes and bacteria- the little guys. But I want to talk […] Continue reading
