In order . to best address the science objectives identified in the Decadal Surveys, and to help achieve the best science return from NSF . Big Science: Big Telescopes. 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?. 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:. 3: Telescopes. Images can be formed through reflection or refraction.. Reflecting mirror. 3.1 Optical Telescopes. Image formation. Modern telescopes are all reflectors:. Light traveling through lens is refracted differently depending on wavelength.. rd. workshop on . . . Large Mm/. Submm.

FMEA Conference/Phi Beta Mu Jan. 16 2015. Achieving Proper Instrumentation. Always start twice as many instruments as you want (need) in your top group for the following year in beginning band.. 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. . Refraction is the _____________ of light as it passes through glass.. II. Reflection: . Reflection occurs when light _____________ off of a mirror.. F. f. I. Refraction: . Refraction is the ___. bending. 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 . 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. Diffraction of Light. Newton pointed . out in his 1704 book . Opticks. , that "Light is never known to follow crooked passages nor to bend into the shadow". . This concept is consistent with the particle theory, which proposes that light particles must always travel in straight lines.. 1. Active / Passive Instruments. .
