* The Solar System

* Through the years, our understanding of the Solar System has been changed by amazing scientific discoveries.

* The Ptolemaic Theory said that Earth was the center of all celestial bodies.

* The audacious Copernican theory change the way of thinking, proposing that the sun is actually the center of the universe and the planets are rotating around it.

* For many years, people believed that nine planets were rotating around the sun. Nowadays, we know that there are only eight planets. New discoveries of Pluto caused the changing of his designation to dwarf planet. (Ekscentar; 2007).

* The Moon Landing occurred in July of 1969 and the human been vision of the universe was different from that day. This event was historical and gave to United States of America its position as a leader and the prestige among the world.

* Nasa scientists have pioneered more than 6,300 technologies during their bid to understand space that are now routinely used in day-to-day living.

1. CAT scanner: this cancer-detecting technology was first used to find imperfections in space components.

2. Computer microchip: modern microchips descend from integrated circuits used in the Apollo Guidance Computer.

3. Cordless tools: power drills and vacuum cleaners use technology designed to drill for moon samples.

4. Ear thermometer: a camera-like lens that detects infrared energy we feel as heat was originally used to monitor the birth of stars.

5. Freeze-dried food: this reduces food weight and increases shelf life without sacrificing nutritional value.

6. Insulation: home insulation uses reflective material that protects spacecraft from radiation.

7. Invisible braces: teeth-straightening is less embarrassing thanks to transparent ceramic brace brackets made from spacecraft materials.

8. Joystick: this computer gaming device was first used on the Apollo Lunar Rover.

9. Memory foam: created for aircraft seats to soften landing, this...
