Exercising in Space
Picture Source When asked what we want to be when we grow up as kids, many of us answer “Astronaut!” We imagine going into space is cool, and it is! Astronauts “floating” in space looks like the best thing ever. One thing we don’t know as kids is that astronauts don’t float in space, it’s actually … Continue reading Exercising in Space → Continue reading
Archeoastronomy – Armillary Sphere and Horolgoe in China
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
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
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

Blog Post #2
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

Gravitational Lens by astronomical objects.
A gravitational lens is an observed image of light that is bent into a circle around the gravitational objects. The general relativity theory or the curvature of the space time is used to explain this amazing phenomena. When there is a sufficiently large gravitational objects such as stars, black holes and celestial bodies in the … Continue reading Gravitational Lens by astronomical objects. → Continue reading

Atmospheres of Planets in Solar System
In many different scientific, astronomical movies, different planets than Earth are often portrayed as hardly habitable environments with almost impenetrable, dusty atmosphere. The atmospheres of these planets seem to vary a lot in many aspects such as density, and components. Among all 8 planets, including Earth in the solar system, the atmospheric conditions of each … Continue reading Atmospheres of Planets in Solar System → Continue reading
