Gravity

Posted on February 11, 2018 by samssolarsystem

Gravity is a fascinating phenomenon of physics that is integral to understanding the universe.  Gravity keeps Earth in orbit around the sun, and the Moon in orbit around Earth.  Any object that has mass, also has gravity. Moreover, the gravitational force between two objects is caused by two factors: mass and distance.  The gravitational force … Continue reading Gravity → Continue reading →

Blog 2 – Archeoastronomy

Posted on February 11, 2018 by natsastronomy

For this post, I’ve chosen to write about archeoastronomy in the ancient Peruvian city of Machu Picchu. I will be visiting the city this summer, which is perfect for this blog! First, a little bit about archeoastronomy. Archeoastronomy is the study of astronomical knowledge from ancient societies and civilizations. Machu Picchu is hidden away in … Continue reading Blog 2 – Archeoastronomy → Continue reading →

Posted on February 10, 2018 by dempsy

Through out the history of China, people are curious about how Sun, Moon and stars move according to Earth, and astronomers have created different tools to assist observing stars. Armillary Sphere The earliest well-known tool is Armillary Sphere (Chinese: 浑天仪), which is designed by Zhang Heng in 117 AD and completed in 125 AD. An … Continue reading Archeoastronomy – Armillary Sphere and Horolgoe in China → Continue reading →

Using Tides as a Renewable Energy Source

Posted on February 10, 2018 by adventuresinspace

Picture Source- Groundsure The rise and fall of tides produces a renewable energy source called Tidal energy. Originally, at the beginning of the 20th century engineers began to use spring tides to generate electricity because of the dramatic change in water levels. While tidal energy has grown in the past century, it is still at … Continue reading Using Tides as a Renewable Energy Source → Continue reading →

Blog Post #3: The Great Attractor

Posted on February 10, 2018 by jonsastroblog

Ever since Edwin Hubble’s groundbreaking observations, it has been known that the universe is expanding. According to his observations, galaxies farther away from us are moving faster than objects closer to us (at least in terms of relative velocities). However, according to more recent studies, the Milky Way and other galaxies near us seem to … Continue reading Blog Post #3: The Great Attractor → Continue reading →

Posted on February 10, 2018 by jonsastroblog

For centuries astronomers have used telescopes to look into the night sky. In 1946 Lyman Spitzer, a prominent astrophysicist in his time, theorized that a telescope placed outside of Earth’s atmosphere would be able to collect much clearer data than telescopes on the surface of the planet. The logic behind his theory is that the … Continue reading Blog Post #2 → Continue reading →
