During the fourth quarter, science classes will study the Earth-moon system including seasons and eclipses, the objects that make up the solar system, and stars and space. Students will learn about the causes of day and night, seasons, phases of the moon, and solar and lunar eclipses as it relates to the Earth-moon system. When studying the solar system, students will examine how scientists' work has expanded understanding and the formation and characteristics of planets, comets, asteroids, and meteoroids. Finally, students will learn how astronomers study the universe using various tools and about constellations, galaxies, the Milky Way, and the big bang theory. CRCT testing will take place from April 19th to

A lecture I'd given on spiral galaxies, barred spirals, mass of galaxies, Sgr A, Elliptical galaxies, standard candles, dark matter, composition of the universe, back in my university days.
You probably need to download the file for the animations to work.
We are in the middle of one of the most exciting moments in history of Astronomy and maybe of mankind. Any minute we will discover our next home. Learn more about the Exoplanet Revolution in this presentation that includes spectacular pictures.

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World (see astrology and astronomy). In some cultures, astronomical data was used for astrological prognostication.
Ancient astronomers were able to differentiate between stars and planets, as stars remain relatively fixed over the centuries while planets will move an appreciable amount during a comparatively short time.

Lab Report for Lab #9:Where in the Milky Way Are We?
Part I: The shape of the Milky Way
1. Look up the morphological classification of the Milky Way. There is a bit more to it than “spiral”. Look for information on morphological classification in text books and/or online. Find out the shape of the Milky Way galaxy.
[Type answer here]
2. Identify the parts the Milky Way. Some possible parts of a galaxy are: bulge, disk, halo, bar, or arm. Knowing the type of galaxy the Milky Way is, you should be able to identify the types of features the Milky Way has. Create a physical model of the Milky Way and identify the features it has. (A globe is an example of a physical model of Earth.) Describe your model and label all possible parts.

3. Use your planetarium software to observe the Milky Way from the northern and southern hemispheres. Based on your observations (without the aid of telescopes or other wavelengths of light outside the visible range) explain how these observations support the conclusion that we live in a galaxy with the shape of your model. Further, determine in what part of the galaxy the Sun must be located to see the Milky Way as we do.

Part II: Mapping the Milky Way with Globular Clusters
Galaxies like the Milky Way have objects, called “globular clusters” that exist in the outer regions of the galaxy (or halo). Globular clusters are dense clusters of stars that are generally free of gas and dust. In galaxies like the Milky Way, the gas and dust are located primarily in the disk. If we want to look for objects that we can see clearly (with no interference from gas and dust) we must observe objects in the halo. In the late 19th century an astronomer named Harlow Shapley devised an experiment to determine the position of Earth in the universe using globular clusters. He chose these objects because of their apparent lack of interaction with the gas and dust in the Milky Way.
Step 4.Explain how Shapley’s experiment could be used to determine the position of Earth within the Milky Way. Given what you already know about the part of the galaxy in which the Sun is located and the information about globular clusters, what information would Shapley need to figure out the position of Earth? For about how many globular clusters do you think he would need to get this information to determine the position of Earth? Describe the experiment and list the steps one would need to take.
[Type answers here]
Step 5. As a group, devise a method for determining the position of Earth within the Milky Way using globular clusters. Decide how many globular clusters you want to observe. Decide what information you need to do the analysis. There may be many different ways of analyzing the data, there does not need to be group consensus for the analysis, but each method that is used should be discussed with the group.
