The speed of light, often denoted by the constant “c,” is faster than anything that we know. Although there have been attempts to get certain particles to travel faster than the speed of light, like when scientists at the CERN laboratory in Switzerland tried to get a hold of neutrinos, no one has successfully brokenContinue reading “Breaking “c” and the Warping of Space-time” Continue reading → Continue reading
There are four different processes that shape planetary surfaces; volcanism, tectonics, erosion, and impact catering. Impact catering is the creation of a bowl-shaped impact crater by asteroids or comets striking a planet’s surface. Volcanism is the eruption of molten rock, or lava from an interior onto its surface. Tectonics is the disruption of a planet’sContinue reading “The Geology of Mars” Continue reading → Continue reading
The aurora borealis and aurora australis – often called the northern lights and southern lights – are mysterious and unpredictable displays of light in the night sky. The most common occurrences of this phenomena take place at higher northern and southern latitudes, less frequent at mid-latitudes, and are almost never seen near the equator. AurorasContinue reading “The Aurora” 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
How did you first picture the universe? Before being taught in school or at home what the universe was like, we often start to wonder about the world around us. This phase in a child’s life often leads to parents being questioned about almost everything. Questions range from why the sky is blue, why isContinue reading “Our Place in the Universe” Continue reading → Continue reading
Although Isaac Newton’s most famous contributions to astronomy are his laws of motion and gravitation, which he published in Principia, Newton also founded modern spectroscopy by publishing his second work, Opticks. Spectroscopy is an essential tool for astronomers because it allows them to not only analyze the presence of certain chemical elements, but also physicalContinue reading “Spectroscopy and Space” Continue reading → Continue reading
Have you ever been fishing? If you have, you probably know that your success partially depends on whether the ocean experiences a low tide or a high tide. But do you know the science behind what causes tides? Below is a quick and simple explanation why. Tides are caused by differential gravity. We know fromContinue reading “What Causes Tides?” Continue reading → Continue reading
The impact that spectroscopy and light has had on the world has not been recognized enough. The discovery of spectroscopy has allowed us to know so much more about astronomy and what makes up our universe. Spectroscopy is the investigation and measurement of spectra when matter interacts with electromagnetic radiation. In astronomy, we look atContinue reading “The Importance of Spectroscopy” Continue reading → Continue reading
Flip a switch. Turn a knob. Push a button. Look in the sky in the day or at night. Each of these actions will allow you to see light, and most people see light as nothing more than an illuminator. Its purpose in the field of astronomy is much more than illuminating the Universe forContinue reading “Light: It’s More than We Think” Continue reading → Continue reading
We all know that light travels fast – 299,792,458 meters per second, to be precise. Still, if the sun were to suddenly disappear into a mysterious void, you and I on Earth would not notice for about 8 minutes and 20 seconds. Or would we? Would we not immediately feel the sudden jolt of ourContinue reading “The Speed of Light and Gravity” Continue reading → Continue reading
