  4. 3.Medieval alchemists studied the North Star, believing it held the secret to perpetual motion.

  5. 4.Stars are formed from dense knots contained in large clouds of dust and gas called nebulae

  6. 5.There is enough matter in the Orion Nebula to produce over 10,000 stars

  7. 6.The ancient Greeks believed that the stars and all other heavenly bodies made a daily rotation around the Earth

  8. 7.By astronomical standards, a star that was formed 2 million years ago is considered to still be in its youth

  9. 8.Supergiants are massive stars that are hundreds of times the size of our sun

  10. 9.Our sun was formed 4600 million years ago and is expected to live a total of 10,000 million years
