Read the following paragraphs concerning space exploration and observations. Use the information in the paragraphs to rearrange the table below, so that the earliest discovery or development is first! DON'T WRITE ON THE SHEETS!
Chinese astronomers made the earliest discoveries, including the satellites of Jupiter. The ancient Greek astronomer Aristarchus, 300 B.C., even believed the Earth went round the Sun. 2000 years later Galileo proved him right. In 200 A.D. the Egyptian Astronomer Ptolemy postulated that Earth was the centre of the Solar System.. A view that was only questioned 1300 years later by Copernicus and then by Galileo.
The 17 th Century produced major developments in astronomy. Lippershey's invention of the telescope in 1619 enabled Kepler to develop his ideas on planetary motion. Galileo developed his own astronomical telescope which he used to observe the Moon and Jupiter's satellites. He also proved Copernicus was correct. Newton then applied his ideas on gravity and forces to planetary orbits in 1687. Halley and Herschel made important discoveries in the 18 th Century, Herschel finding a planet in 1781.
The 20 th Century has had many astronomical events. The number of planets increased to nine in 1930 and van Brown experimented with rockets ten years later. This latest development enabled the Russians and Americans to develop space technology, which first launched satellites and then put man on the moon
