Retrace the steps of astronomer Edwin Hubble, who in 1929 shocked the
world when he discovered that the universe was expanding. |

Color |
Look up at the sky - what do you see? If you're near a city, you may
see a few bright white stars. But you're not really seeing the full story of the sky -
stars come in a dazzling array of colors, from bright blue to white to deep red. In this
project, you'll see stars of all colors, and you'll learn what causes the color of
a star. |
 |
Spectral Types |
How do astronomers make sense of the millions of stars they see? In
this project, you will learn by classifying the stars yourself. |
 |
Hertzsprung-Russell Diagram |
Learn how astronomers study the lives and times of stars, which live for millions
or billions of years. |
 |
Galaxies |
How do astronomers study galaxies, which can be millions or billions of
light-years away - so far away that most just look like fuzzy patches of light?
In the Galaxies project, you will learn by examining galaxies yourself. |
 |
Sky Surveys |
Learn about how astronomers map the sky, from ancient times to today's
cutting edge technology. |
 |
Quasars |
Learn about quasars, the most distant and mysterious objects in the universe. |
 |
Image Processing |
Learn what goes in to the beautiful images you see on SkyServer. You'll
never look at a picture of the sky the same way again! |
