|Today we will use more of a hands-on approach to learn about stars and their properties. A major topic of the last lab was the evolution of stars. Stars, like people, have lives. They are born, they live out their lives and then they die. Of course, stars do it on much longer time scales. You may be wondering how astronomers know this and whether it can be proven that stars evolve. One of the questions you answered last time was "How do we know stars evolve?" Well, they must.......|
In this lab you will operate a virtual observatory to obtain images of stars and nebulas. You will study these images and determine some properties of stars. In the process you will learn how astronomers know that stars evolve.
The images that our virtual observatory uses come from
"The Digitized Sky Survey". Many of the images
were recorded by the world famous Oschin Schmidt
Telescope at Palomar, California. This f/2.5
telescope has a 1.26 meter (48") aperture with a
focal length of
