    Welcome to week 1 of IntroAstro!! Our journey through the cosmos begins this week on Tuesday, Nov 27th, 12:00 pm (noon) EST.

    Auspiciously, if you look up this evening - almost anywhere - you will be treated to a pretty conjunction (what astronomers call an event in which two objects appear near each other in the sky) of the full Moon and Jupiter - the two brightest objects in the night sky. For those living at longitudes between Europe and Eastern Asia this will create a dimming of the Moon due to a deep penumbral lunar eclipse ar 14:33 GMT on November 28.

    This week we will begin our discussion by thinking about the apparent motions of objects in the sky, understanding what they tell us, and developing some mathematical machinery to describe them. At the end of the week, you will be able to follow the reasoning that led me, upon looking up a few days ago, to realize a conjunction was likely coming tomorrow night, and why a conjunction with Jupiter at full Moon suggests an eclipse is likely. We will not take the math all the way to making precise long-term predictions of sky events like eclipses. Modern software can take care of the details. However, we will know enough to explain what goes into the software and make rough estimates of our own.

    We suggest you start by clicking the Start Here! button on the Navigation bar to the left hand side to learn some general things about the class.

    This week’s material is covered in six video clips, with in-video quizzes to help you see how well you are following the discussion. There is a two-part homework assignment due Monday, Dec. 3 at 12:00 pm EST. Before tackling this, you should do the quick "Sample Homework" to help familiarize yourself with the types of questions you might encounter and the way the system handles your responses.

    We are all excited to “meet” you finally, and we’d like to know a bit about you. If you have not yet filled out the survey please do so. In addition, we have a Forum thread asking you where you are from and why you are taking this class. Finally, if you like, you are invited to join an optional Facebook Community for our class.

    “See” you tomorrow!
