Retrograde is an apparent motion. An objects appears to be in retrograde when it is lapped by another object that is the pointContinue reading “What is retrograde motion?” Continue reading → Continue reading
Ever wonder why the siren of a police car or a firetruck seems to change in pitch after it passes by? Well, the phenomenon is known as the Doppler Effect. The Doppler Effect explains how sound, like in the example above, or light waves are manipulated by the movement of an object in relation toContinue reading “The Visible Doppler Effect” Continue reading → Continue reading
Many are familiar with the concept that the Moon creates high and low tides on Earth, but few know that the Sun also plays a role in the process. Tides are formed from the gravitational forces of the Sun and Moon pulling on the Earth differently in different places due to variations in distance. TheContinue reading “Spring and Neap Tides” Continue reading → Continue reading
Light appears almost instantaneous to the naked eye. This seems especially evident on the Fourth of July, watching a firework explode, only for the boom to hit you seconds after the colorful light hits your eyes. It does not seem like something so fast and instant could be affected by a force such as gravity.Continue reading “Gravity’s Effect on Light” Continue reading → Continue reading
Gravity waves have been speculated to exist ever since Einstein set a speed limit to the universe, the speed of light. When Newton came up with the gravitational force equation, it only considered mass and distance when calculating the force. It did not take into account that if one mass disappeared, then that information ofContinue reading “Gravity Waves” Continue reading → Continue reading
Every time I pick up The Cosmic Perspective to do the assigned reading, I end up learning something new and exciting. This unit, while I was reading Chapter 3 “The Science of Astronomy” one particular part struck me. The textbook mentions a Spanish monarch named Alphonso X who lived from 1221 to 1284. Alphonso XContinue reading “Alphonso X” Continue reading → Continue reading
Space travel is a relatively new concept compared to the overall age of astronomy. From Armstrong to Koch, sending people into space is still an amazing feat with distances that don’t dare to go beyond our moon. But what if this could change? What if, like our telescopes, we could travel to Jupiter or PlutoContinue reading “Time Warps- More Than Just Sci-Fi?” Continue reading → Continue reading
