Good afternoon. I captured this photo while trying to set up a cute video using Astronomy Cast/Universe Today as the audio track. The subject was variable stars. Fraser and Pamela do a great job. I also got photos of Algol in the constellation Perseus. The meteor showers should be coming up soon.

Towards the end of the year, Mars will be traveling in the constellation Gemini. There is one particular variable star that really upsets me. I guess that what makes star gazing great.

Planets are milestones of time

This should be fun. Charlie is suppose to be born on October 10, 2007. I know Charlie exists because I saw him in a picture call a s.....gram. I know his name is Charlie. How do I know that? Because his mother told me. Let me get started.

Retrograde motion--astronomy lecture note Rev-1

Wow! This is wild. The last post(Rev-0) I couldn't get the links to start up. I guess I should get started. The purpose of this post is to get a line of thought for an astronomy lecture.
