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:. The most important property of a telescope? . No, it’s not it’s “power” or magnifying ability, it is……. Its . Light Gathering . power! So, . t. he diameter of the mirror or lens is THE most important property. 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.. 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. . antenna-coupled Transition Edge Sensor bolometer detectors . for studies of the . Cosmic Microwave Background. Aritoki Suzuki*. 1,2. , Chris Bebek. 1. , Maurice Garcia-Sciveres. 1. , Stephen Holland. , Floating Point Numbers. Serialization. Serialization is the concept of turning any data structure or objects into a stream of bytes.. In C, we lack proper objects so most of our data structures are already bytes in memory.. 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.. 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? . . Size does matter. The bigger, the better. 2. Resolve detail. 3. Magnification. Only important for solar system objects. Refracting Telescopes. Cheap. Good for bright objects. Basic design. Reflecting Telescopes.
