Galileo and the Telescope

Galileo and the telescope have become synonymous over the ages. It’s difficult to think of one without also considering the other. But it was not Galileo who invented the telescope– although he was one of a few who revolutionized its use for astronomy. The telescope’s origins can be traced back to English philosopher Roger BaconContinue reading “Galileo and the Telescope” Continue reading

Retrograde motion

Like the ancients Greeks, I also had some trouble understanding retrograde motion and how it’s possible that it might seem that some objects in the sky move in reverse motion. Instead of rising in the east and setting in the west, it appears that some objects move in reverse from west to east for a […] Continue reading

What makes the Tides happen?

This blog will be referencing information sourced from the Tides: Crash Course Astronomy #8 video. We know that mass has gravity, and more mass had more gravity. This raises the question, why does the moon have a greater impact on the Earth’s tides than the Sun, even though the Sun has such a greater gravitational …

How Stonehenge is Astronomical

Stonehenge is a prehistoric monument that is basically a ring of stones. Located in Salisbury, England, tourists come everyday to see the beautiful mystery. There are many legends and myths about how Stonehenge was created. According to different theories it could have been built by wizards, Danes or it was ruins from Roman Temples. Although […] Continue reading

Gravity in Solar System

Acceleration due to gravity (g) is different for different planets due to their diverse masses and radii. Physicists usually figure out the by the formula g = GM/r**2, where G is the Universal Constant of Gravitation (6.67 * 10**(-11)), M is the mass of the planet, and r is the radius of the planet. By […] Continue reading

Tides on Titan

As we learned in class, different celestial bodies can have varying tidal forces depending on their masses in relation to the object of interest. This phenomenon was mainly explored by the tidal forces on the Earth by the Moon and the Sun. In order to calculate the gravitational forces between two objects, we utilized the […] Continue reading

Black holes and spacetime | blog post II

Black holes are areas in spacetime where the gravitational force is so strong that nothing can escape. This includes forms of electromagnetic radiation like light. Current general relativistic models depict black holes as a taking on spheroid shapes, with an interminably long “tail” leading to its point of singularity. Singularity is a geometric point where […] Continue reading

Archeoastronomy: the Ancient Greeks

The quest for knowledge about the universe we live in is not a modern phenomenon. Many cultures throughout history have devoted a significant amount of time and resources in pursuit of this knowledge. One ancient civilization that dramatically improved our knowledge of astronomy was the ancient Greeks. One of the main goals of Greek astronomers […] Continue reading

We know the way

A long time ago, before we had our fancy GPS and siri to tell us where to go and how to get to and from places, we had to rely on the sky, more specifically the stars (the Sun included). We learned to use the stars and Sun to tell time and by creating angle […] Continue reading

An Eclipse’s Blinding Beauty

We’ve all been told when we were children to NEVER stare directly into sun. Whether it be our parents, teachers, or someone on tv, right before we were sent out to get our daily exercise, we were made sure to know to avoid making eye contact with that big, bright, bulb in the sky. But […] Continue reading
