Have you ever been to a beach and wondered why at some times of the day, the ocean water reached further onto the land than at other times of the day?  You may have heard the terms ‘high tide’ and ‘low tide’. Tides are caused by the gravitational force of the sun and moon, as… Continue reading

Gravitational Redshift

Most of us know about redshifting, a phenomenon of the Doppler effect. This is the change in frequency of a wave, both mechanical and electromagnetic, for an observer when there is relative motion between the source and the observer. For example, when an observer is moving closer to a wave source, each successive wave front […] Continue reading

The Scale of Atoms and Modern Processors

Everyone knows that atoms are small, but exactly how small is small? This new video by Kurz Gesagt explores this question, and the sheer scale is mind boggling to try to imagine. Among the analogies used is that of filling rooms with rice grains; if the end of your finger was the size of the room, and […] Continue reading

The Early Telescopes

The earliest working telescopes was made around 1608 with many who claimed its discovery. The design was simple; a convex objective lens and a concave eyepiece allowed the user to see further. In 1655, astronomers had build more powerful telescopes using a design by Kepler. This design used a convex objective lens and a convex […] Continue reading

A Smiley Face in Space :)

A picture taken by Hubble shows what appears to be a face complete with two eyes, a nose, and a smile. The two eyes are actually galaxies while the smile is made up of curving light that forms a partial circle around the figure. However, the smile doesn’t exist. There is lots of immeasurable and […] Continue reading

The James Webb Space Telescope

The James Webb Space Telescope (JWST or Webb) is set to be the official successor to the Hubble Space Telescope, due to launch is 2018. In order to understand how the JWST will be improving on the Hubble, I think it is first important to understand some of the light aspects of space observation. Model […] Continue reading

Archaeoastronomy

One of the topics I found most interesting to think about in these readings is the topic of archaeoastronomy. I had never even heard of this concept before reading chapter 3! It’s very interesting to think about how ancient civilizations viewed the sky. Some, like the Blackfoot tribes in the Americas, viewed the Sun, Moon, […] Continue reading

Archaeoastronomy: A Connection between Ancient and Modern Cultures

I have always been fascinated by different cultures and how cultures interact with each other. Thus, whenever I learn about a new subject, I always try to approach it from a cultural perspective. I had not found a way to do so with astronomy until I learned about the field of archaeoastronomy. I am especially […] Continue reading
