Solar Storms
Who knew there were actually storms on the surface of the earth? Well, they aren’t the storms that we are used on earth. Actually, they are quite different. Storms on the sun occur when magnetic fields throughout the sun passing through sun spots and prominences spontaneously shift dramatically. The most known of these storms are […]

The Pock-Marked Sun God
Sunspots are areas on the Sun that appear darker compared to their surroundings because they are cooler than the areas around them. This does not mean that the spots are actually cold, but relative to the 5800K temperature of the rest of the Sun, sunspots are much cooler at 4000K. Magnetic fields prevent the hotter […]

Coronal Mass Ejections and You
A coronal mass ejection (CME) is a massive outburst of Sun matter interweaved with magnetic field lines. This Sun matter basically consists of superheated particles accelerated at millions of miles per hour. This ejection isn’t self-contained, a lot of this stuff just goes shooting into space. This wouldn’t be so bad in of itself, except […]

Nuclear Fusion in the Sun
At the core of the Sun, and every other Sun like star, a process called fusion takes place. Fusion describes a process where light elements, such as hydrogen, get fused together to form heavier elements, like helium. Fusion happens due to the intense pressure of gravity acting on the suns mass. A byproduct of this […]

The Sun’s Absorption Spectrum
Absorption spectra occur when a hot solid or liquid or very dense gas give off a continuous spectrum, with all colors, and then that continuous light moves through a thin gas that is cooler than the source of the continuous light. This thin gas absorbs some of the light being given off by the source […]

Lunar and Solar Tides
Tides are a fascinating effect of the Moon and Sun’s gravitational forces acting on the Earth. They are a visible sign of how distance effects the strength of a gravitational force. Because the Sun is so large, it has the greatest gravitational force acting on the Earth. However, because it is so far away, the […]

The Sun and the Missing Neutrinos
First of all, what is a neutrino? It’s an elementary particle, like an electron or a photon, but it hardly interacts with matter. In fact, billions of neutrinos pass through you every second, but you don’t feel them. This characteristic makes them hard to detect. It’s no wonder that, in recent history, scientists thought some […]

It’s kind of in the name
captain’s blog, Stardate 69536.8 you, potentially: “wait Phil, isn’t the Stardate of blog post 2 is pretty close to the Stardate of blog post 1?” me: “Shhhhhhhhh.” This last week we looked deeply into the movement of the sun throughout the year. Without discussing it, we were inherently learning about solstices and equinoxes, a topic […]

The Zodiac Signs
Image link The zodiac signs surround a lot of peoples’ daily lives, in that most people look to a horoscope to direct their lives. The fact that the position of the stars at a certain time can tell so much about a person’s individual personality is absurd, yet we attribute personality traits to the constellations.…
