Watching the skies is an ancient occupation. The Sumerians who lived in the Middle East began studying the movements of stars and planets about 3500BC.
Chinese astronomers built an ________________ and made maps of the Dragon, Phoenix, Tiger and Turtle ________________ around 2000 BC.
These early sky gazers believed the movement of stars was a guide to the future. Although ________________ is still popular, modern telescopes are used to study our universe.
Telescopes help us learn about black holes, meteors, supernovas and all sorts of exciting things.
Mapping The Skies
Find words that mean the opposite:
last, disconnect, inefficient
Star charts list the position and brightness of stars, planets, comets and other objects. Until recently scientists sat up night after night, carefully noting what appeared in the night sky.
Chinese astronomer Shih Shen made a map of about 800 stars, meteors and sunspots in fourth century BC. In the west, Greece's Hipparchus was the first astronomer to make a map of 850 stars in 129BC.
Today's astronomers link their telescopes to computers. These computers convert images from the telescope to maps. Computers compare new pictures to existing star charts and only alert scientists if they find something new.
This modern system means sky-gazing is much more efficient. But do you think it's as much fun?
Find words that mean the following:
rounded, distant, look at
The idea of looking through curved lenses to make far-away objects look bigger is very old. But as glass lenses are very hard to make, it wasn't until 400 years ago that the first telescopes were built.
The first person to apply for a telescope patent was German-Dutch inventor Hans Lippershey. He called his invention a 'kijker' (pronounced KEI-ker), a word that means 'looker' in Dutch.
When Lippershey first showed his invention to the public on October 2, 1608, he suggested it would be useful in battle.
In 1609 Italian inventor and scientist Galileo Galilei made a similar but better tool. As Galileo was the first to use it to examine the night sky, he is sometimes called the inventor of the telescope as well.

One of the most famous telescopes on/in earth is The Very Large Array in New Mexico, in the United States. It features in films like Contact and 2010: Odyssey Two.
Telescopes are also travelling at/in space. The Hubble Space Telescope has been orbiting the Earth and sending us pictures since 1990.
