Presentation Transcript


is transparent


ERAU Astronomical Observatory


Meade 12.375 inch Schmidt Cassegrain Reflecting Telescope


Ground Based Telescopes

Optical

Infrared

Radio


Refracting Telescope


Refractors Tend to be long….


Reflecting Telescope Designs


Reflecting Telescopes are Compact….


A Prism Spectrograph


A Spectrum


A Modern Spectrograph


An Electronic Imaging Camera called a CCD


Angular Resolution


Angular Resolution depends on two things…

1. The wavelength of light :  (in meters)

2. The size of the telescope mirror (or dish) : D (in meters)

 = 2.5 x 105 /D

 is the angular resolution in arcseconds


A Radio telescope “dish”


The Very Large Array (VLA) in New Mexico


Atmospheric Blurring


No atmospheric blurring in space….


is transparent


Spitzer Space Telescope


Chandra X-Ray Observatory


Compton Gamma-Ray Observatory


The sky at five different wavelengths

a- Visible

b- Radio

c - Infrared

d - X-ray

e - Gamma ray
