A galaxy is a grouping of stars. All but a few stars in the universe live in galaxies. Our Sun is just one of at least 200 billion stars in our own Milky Way Galaxy. With our best telescopes, we can look deep into space and see billions of galaxies. Galaxies come in all different shapes. Some are spiral shaped like our own Milky Way. Some are like a circle or a flattened circle. Others seem to have no particular shape at all. Make your own collection of beautiful galaxies. Suspend them on a mobile so they turn and sparkle in the wind. Here's how to make your Galactic Mobile. |
