All About Telescopes

Hubble Space Telescope In the world of telescopes, there are two main types: refracting and reflecting. The first telescopes created by astronomers in the 1600s were refracting telescopes. These work much like eye glasses. A curved lens bends the light into the observer’s eye. The bigger the lens the further into space a person could […] Continue reading

Retrograde Motion

Diagram of Retrograde Motion Retrograde motion is when the motion of a planet seems to reverse direction in the sky. The name of this phenomenon is derived from the Latin word retrogradus, which means “going backward.” This motion, however, is purely an illusion as the planet’s motion does not actually change and start moving backward […] Continue reading

Understanding Retrograde Motion

the planets as seen from Earth Retrograde motion is when a planet appears to move backward in its orbit relative to the rest of the night sky. Planets such as Mars and Jupiter can be seen in retrograde motion. Retrograde motion occurs due to the movements and relative positions of other planets around the sun. […] Continue reading

Gravity on Earth versus other planets in our solar system

Exploring how gravity on different planets in our solar system is different. Gravity definition: Gravity is the force that attracts items to a planet or other body’s core. Gravity keeps the planets in orbit around the sun. Since all the planets weigh differently, and have different radius this causes the gravitational pull of each planet […] Continue reading

Gravity & General Relativity

You throw something up in the air and it falls down. Why? Gravity, obviously, everyone knows that. But what really is gravity? By most common knowledge, gravity is one of the four fundamental forces, and has a lot more to it than just making things fall. Gravity actually works as an attraction between two masses, […] Continue reading
