You can check out various scopes, and get a look at a number of beautiful objects of the night sky. Stars and Constellations Finding constellations and groups of stars is enjoyable, and being acquainted with the sky will be invaluable upon further exploration of the universe. Stars are giant balls of hydrogen gas that formed in gas clouds like the Orion nebula. They have so much mass, that the pressure in the deep interior is great enough to combine, or fuse, hydrogen atoms together. This fusion yields a great deal of energy, some of which we can see as visible light.
Stars come in great variety of sizes and brightness, or luminosity.
Their surface temperatures determine their color. Very hot stars are blue or white, medium temperature stars like our sun are yellow, with the red stars being the coolest. Very bright blue or white stars can be much further away from us than cooler stars, even though they appear closer, although red super giants can also be seen at great distances from us. Constellations are recognized patterns of stars that form animals or figures, many named from very ancient times. It is enjoyable to try to see the pattern form into something that has been recognized and named for many centuries, many dating back to the Ancient Egyptians and Babylonians.
