Andrew McKay Northrop Grumman Aerospace Systems. 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.. . 6. – Observing at Other Wavelengths. ASTR 101. Prof. Dave Hanes. Why Other Wavelengths? . To Study . New Sources. . In Historical Order. 1. Radio radiation 3. X-Rays. 2. Infrared sources 4. Gamma rays. 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.. So, if you are not sure, do your best to guess.. Please bring pencil(s) so that you can fill out. the scantrons.. No other accessories (calculators, cell phones, …) are allowed.. Important: Anything in the posted slides that I did not cover in class could be on the exam.. Single-Dish . Radio Telescopes. Dr. Ron Maddalena. National Radio Astronomy Observatory. Green Bank, WV . March 2016. ©Associated Universities, Inc., 2016. National Radio Astronomy Observatory. National Laboratory. 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. . The SETI Project. Lesson 6: Where to Survey. Questions? Please contact Carolyn Donelan @ carolyn.donelan@richlandone.org.. The GAVRT SETI Project. The GAVRT SETI Project will search most of the stars in our galaxy, in all the frequencies the telescope (named DSS-28) can reach (in 200 MHz increments).. SPECTROSCOPY. Uses visible wavelength split into colors. Doppler shift. Wavelengths change when object is moving. Red/ . Blue. Shift. RECEDING (moving away) objects show a INCREASE in WAVELENGTH- red shift.
