Space exploration has developed through key astronomers and scientists throughout history. Early astronomers like Aristotle and Copernicus challenged ideas that the Earth was the center of the universe and that planets orbit in perfect circles. Galileo used early telescopes to make discoveries on other planets and moons. Isaac Newton discovered the law of gravity and that gravity is what holds planets in orbit around the Sun. Later, Edwin Hubble showed that the universe is expanding. Space exploration uses astronomy and technology to explore and study outer space. Malaysians can watch live Olympic events in other countries through television broadcasts and live streams online.

5. • ‘Planets’ orbits are elliptical,not circular!
• ‘I found law of gravity!’
• ‘I think the planets remain in their orbits
because of the gravity force of the Sun
G
• ‘I assure you,the universe is expanding!’
