Blog #2

Posted on January 25, 2016 by astronomer0110

The topic of zodiac signs and how they the constellations and the ecliptic is fascinating to me. Humans have recognized the appearance of certain constellations behind the sun throughout a large part of history. Of course, the true cause of the changing zodiac signs is that the earth’s position changes relative to the sun and […] Continue reading →

Common Misconception: The Earth’s Tilt At An Equinox

Posted on January 25, 2016 by andyastronomer

Upon visiting Dr. Grundstrom with a homework, I caught myself making a pretty silly error regarding the Earth’s Equinoxes. Looking at one of the homework questions for the seasons, I was asked to rank the order of several globes in order of how much daylight they received. One of the globes stood straight up, rotating […] Continue reading →

Solar Eclipse

Posted on January 25, 2016 by OscarBen

A total solar eclipse. Source: SoftPedia There are two types of eclipses, lunar and solar, but I’d like to talk about the latter. Solar eclipses can be broken down into four subtypes: total, partial, annular and hybrid. In order for any of these to happen, the Sun, Moon and Earth must form a straight–or almost… More Solar Eclipse Continue reading →

Precession of Earth

Posted on January 25, 2016 by sarabkeller

I think one of the most interesting topics in Chapter 2 of the Astronomy textbook is about the concept of precession, or the gradual change in the rotational axis of Earth. The direction of Earth’s axis rotates on a 26,000 year cycle. That may mean next to nothing to us in our lifespan, but precession will gradually […] Continue reading →

Every morning the sun rises on the Eastern horizon, and every evening the sun sets in the West. I have seen approximately 7800 of these sunrises and sunsets over the course of my life. Every night I go to bed in the dark, … Continue reading → Continue reading →

The Great Shift

Posted on January 25, 2016 by alecsolarsystem

The Earth is like the top from Inception. As it spins around at very high speeds it wobbles or “precesses” back and forth as the force of gravity from the Moon and Sun tug it from different directions, but it will never fall over. This movement, although much slower and less noticeable than the Earth’s […] Continue reading →

Name That Constellation

In English, we typically use names derived from Greek and Roman mythology for the constellations, referring to constellations such as Orion and Pleiades […] Continue reading →

Constellations of the East

Posted on January 23, 2016 by jasperluastronomy

When we were looking at star maps inside of Stellarium during class, I couldn’t help but think about how arbitrary all of the constellations seemed. If I didn’t know what shape to look for, I don’t think I would ever have found the same patterns in the sky. I decided to study the Chinese constellation system […] Continue reading →

The best way to propose to an astronomer: Solar eclipses

Posted on January 23, 2016 by d51blog

  A solar eclipse, which is the only acceptable way to propose to an astronomer, is a fairly uncommon event which occurs when the Moon passes between the Earth and the Sun. Although the Moon is much smaller than the Sun, it is able to completely block the Sun because it is much closer to the […] Continue reading →
