Overview of Basic Astronomy

About 400 years ago Galileo’s used first telescope to study the skies

On July 21, 2009 man landed on the moon

Earth and Our Solar System

What do we know about it in terms of Astronomy … What do we know about it in terms of Astronomy … The Earth is our home in a vast galaxy The Earth is our home in a vast galaxy

On August 11, 2009, Saturn, made its 170,000-mile-wide ring system disappear. Saturn has been performing the "ring plane crossing" illusion about every 15 years.

Relative Sizes of Earth & Moon

Pluto is now considered as a dwarf planet. A "dwarf planet" is a celestial body that: (a) is in orbit around the Sun, (b) has sufficient mass, (c) is (nearly round) shape, and (d) has NOT cleared the neighborhood around its orbit.

Asteroids & Comets Asteroids are small celestial bodies composed of rock and metal that move around the sun and are round/irregular shapes. Comets are a chunk of frozen gasses, ice, and rocky debris that orbit the Sun. When a comet nears the Sun, heat vaporizes the icy material producing a cloud of gaseous material that looks like a tail, called a coma.

Meteor-Shower This happens each summer as the Earth's orbit takes it through debris scattered by the tail of comets.

Let’s take a look beyond our Solar System... Solar System...

Conclusion Just ponder, whether this vast galaxy and thousands of galaxies like this have come into existence by themselves, or there is a creator of all this??? Think seriously !!!
