Part 3: Gravity in Space. Telescopes were first invented around the year 1600. . Galileo . Galilei was an early astronomer who first used telescopes to view objects in our solar system. . He . made many important discoveries including: the moon was covered in mountains and Jupiter had 4 large moons.. Jon Holtzman. NMSU Astronomy. Telescopes are light buckets: bigger buckets collect more light, and faint (far away) objects don’t produce much light!. Why build bigger telescopes?. In principle, bigger telescopes make sharper images:. Optical Telescopes. Ground based and on satellites. Observations are recorded using a camera instead of the human eye most times. . This is so we can separate colors into light and using times to study changes over time.. . Our . Objectives. To . determine the . physical properties of the . stars;. to learn how . they . differ; and to understand why. those differences arise . We can now get around . the problem of the variety .

By . taking our sense of sight far beyond the realm of our forebears' imagination, these wonderful instruments, the telescopes, open the way to a deeper and more perfect understanding of nature. How astronomers study space. Electromagnetic Radiation (EMR). Light can travel through empty space. All EMR travels at the speed of light. . 3 x 10. 8. m/sec. Astronomers study different types of EMR. Why do you say, O Jacob,.     and speak, O Israel,. ‘My way is hidden from the Lord,.     and my right is disregarded by my God’. ?. Have you not known?
