Welcome to the astronomical image and movie page for Physics 1060, Introduction to Stars & Galaxies.

These are arranged by topic within each of the course units. I will be showing many of these in class, but you are welcome to browse around on your own at any time.

With the exception of 5 foreground stars that lie in our Milky Way Galaxy, nearly every object in this image taken by the Hubble Space Telescope is a galaxy each containing 10s of billions to trillions of stars. The large grouping of galaxies filling the center of this image is the most massive galaxy cluster known, and lies 2.5 billion light years away. Most of the small blurs of light are galaxies even more distant. If you look carefully, you may notice something peculiar occuring within this image. This image spans an area in the sky corresponding to the apparent size of a dime at distance of 53 feet.
