Do scientists know all about our Do scientists know all about our galaxy, the Milky Way? No. There is much galaxy, the Milky Way? No. There is much that waits to be discovered. This that waits to be discovered. This PowerPoint show focuses on celestial PowerPoint show focuses on celestial bodies. Celestial bodies are constellations, bodies. Celestial bodies are constellations, comets, meteors, asteroids, galaxies, and comets, meteors, asteroids, galaxies, and basically everything in space.basically everything in space.

CometsComets

Comets are made of dust, stones, ice, and frozen gases. Their tail is made of gas and dust and faces away from the solar wind coming from the Sun. They are only a few miles across, but when the sun heats them, they turn to gas and expand to thousands of miles across. Their ellipse (orbit) is shaped like a flat beach ball. One famous comet is Halley’s Comet. It is seen every 76 years. It’s discoverer was Edmund Halley, who discovered it in 1682.

Stars and ConstellationsStars and Constellations

Stars are a gaseous mass within space that give Stars are a gaseous mass within space that give off light. They live more or less than 10 billion off light. They live more or less than 10 billion years. One of the mysteries about stars is why do years. One of the mysteries about stars is why do the stars twinkle? We have the answer. As the the stars twinkle? We have the answer. As the light travels through earth’s atmosphere, light travels through earth’s atmosphere, turbulence in the atmosphere messes with some turbulence in the atmosphere messes with some and make them look like they are twinkling. and make them look like they are twinkling. Constellations are a group of stars that form a Constellations are a group of stars that form a path, creating a picture. Long ago, people named path, creating a picture. Long ago, people named stars and constellations after animals, gods, and stars and constellations after animals, gods, and heroes. The next couple slides will go in depth heroes.
