Jodrell Bank Discovery Centre. Contents. Part 1: Gravity on Earth. Mass or weight?. The strength of Earth’s gravity. Part 2: Big Telescopes. How do we see space?. Part 3: Gravity in Space. Essential Questions- You should be able to answer these questions by the end of the PowerPoint.. What is the purpose of a telescope?. How do refracting telescopes work?. How do reflecting telescopes work?. Telescopes. Key Concepts. What are the regions of the electromagnetic spectrum?. What are telescopes and how do they work?. Where are most large telescopes located?. Telescopes - Key Terms. Telescope. 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.. 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.. rd. workshop on . . . Large Mm/. Submm. Telescopes . . . in the ALMA Era. March 10, 09:00 – 18:10. March 11, 09:00 – 17:40. COSMOS Lodge. Conference Room. Background of the workshop. Types of Telescopes. A telescope collects light over a large area and focuses it in a . small area where it can be viewed with an eye or a camera. This can be done in 2 ways:. Refracting Telescopes. Agenda. Turn in Displacement Lab work. Turn in Permission slips. Notes on . Studying Space & . Exploring . Space packet. Studying space from Earth. Tele. = distance. Scopos. = to watch. Light and radiation (energy in the form of waves that travel through empty space). 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 we need telescopes?. Humans can only see 6000 stars at night and cannot resolve (discern) the detail of objects in the sky if they are too close together. . Humans also cannot see anything but visible light. . History. In 1773 Herschel invented a large . reflecting . telescope and discovered Uranus. This was the first “new” planet.. In late 1800’s . Kuiper. found methane gas in Saturn’s moon with the largest . Agenda. Turn in Displacement Lab work. Turn in Permission slips. Notes on . Studying Space & . Exploring . Space packet. Studying space from Earth. Tele. = distance. Scopos. = to watch. Light and radiation (energy in the form of waves that travel through empty space). Ninth Edition. Neil F. Comins • William J. Kaufmann III. CHAPTER 3. Light and Telescopes. WHAT DO YOU THINK?. What is light? . What type of electromagnetic radiation is most dangerous to life?. What is the main purpose of a telescope? .
