Discover the Universe!
Welcome to the amazing world of astronomy! Astronomers spend their time discovering the
nature of space and everything in it. As big as our planet Earth is, it is just one of eight planets
orbiting the sun, which is just one of billions of stars in our home galaxy, the Milky Way, which is
just one of billions of galaxies in the universe. So you can see that it will be a long, long time, if
ever, until astronomers run out of things to discover!
Your Own Planetarium
Have you ever been to a planetarium show? Do you remember when you sat back and saw the
night sky projected by a huge star projector, while the astronomer guided you on a journey
through space and time? Remember how fun and interesting that show was? Your planetarium
does much the same thing, right in your own room.
Your planetarium allows you to...
•
Project stars, outlines of the constellations, and their names on the walls and ceiling all
around you
•
Project the night sky for any season or month of the year with its one-piece
fully-integrated Star Sphere — no separate overlays to break or lose
•
Accurately project the night sky by season, date and hour
•
Project the night sky in its correct directional orientation
•
Treat yourself and your friends to an exciting sight and sound tour of the night sky.
With your planetarium, you will learn the locations of the brightest and easiest-to-find
constellations, stars and planets. By taking the tour and reading this guide, you will come away
with a good understanding of the night sky.
What Is a Constellation?
If you look at the stars in the night sky long enough, you will notice how groups of stars form
familiar objects, something like connect-the-dots pictures. Many centuries ago, people who
gazed at the stars noticed pictures out there— and gave names to them. This helped them
create a "map" of the night sky, making it easier to locate the stars.
But these figures are not really sitting out there in space. They are only imaginary patterns
created by the relative positions of the stars as we see them from Earth. Some stars that appear
to be right next to each other are in fact very far apart. They just look close together from where
we are looking at them. If you could somehow see the night sky from another part of the galaxy,
the relative positions of the stars would be completely di erent and you would be able to
discover totally new constellations.
