-
This course will provide the student with an introduction to the concepts of modern astronomy, theories on the history of the Universe and the formation of the Earth and the solar system. Students will compare the Earth's properties with those of the other planets and explore how the heavens have influenced human thought and action. The course gives a description of astronomical phenomena using the laws of physics. The course treats many standard topics including planets, stars, the Milky Way and other galaxies, black holes to more esoteric questions concerning the origin of the universe and its evolution and fate. Although largely descriptive, the course will occasionally require the use of sophomore-high level mathematics.Up coming astronomy events

Orion is visible in the early morning hours beginning on the August through early December. Orion will start rising in the East before dawn the first part of August and, over the next several months, rise earlier and earlier until, by December, it rises around 9:00pm and sets in the West just before sunrise.
This means that, beginning in December, Orion is visible during the evening hours. The great constellation is at its most impressive during the crisp cold evenings of winter when it is high and easy to spot in the night sky. Orion remains visible in the evening until around the first of May, when in drops out of our sight until the cycle starts over again the following August.
The easiest way to find Orion is to look for the three stars in his "belt". There isn't another group of three stars in the sky that are spaced so evenly and so easy to find. Once you have found his belt, the rest of the giant constellation is easy to spot. }

That our seasons come from the tilt of Earth's axis relative to its orbit of the Sun is easy to grasp, once you have used this Interactive. It shows the flow of seasons as the planet orbits the Sun, the angle of the Sun's rays for a given location on Earth, how temperature varies at that location, and how the Sun's path varies in the sky by season. Choose from 3 planets to see how their seasons reflect their unique tilts, or customize the tilt. What would "winter" be like if Earth had no tilt? This Interactive will show you.
Everyone is aware that the Moon changes its appearance from day to day. This Interactive will show you why, and allow you to understand how the Moon's phases are linked to where and when each phase appears in the sky. If it's sunset, and the Moon is directly overhead, what phase must it be? Is it possible to see the full Moon during the day? What exactly does a "waxing gibbous" Moon look like? Playing with this Interactive will give you a real understanding of how the interplay between Moon, Earth, and Sun creates what we see.
