Infrared Astronomy

Slide 2

Infrared Light In 1800 William Herschel found "undetectable light" It\'s vitality with all the same attributes as noticeable light, yet is not detected by the human eye The light Herschel found was just past the red part of the range. So it was named "infrared"

Slide 3

The Spectrum of Light Visible light is a little division of the Electromagnetic Spectrum Gamma beams - billions of waves per inch Radio waves- - up to miles-long wavelengths Low Energy Waves High Energy Waves

Slide 4

All items in the Universe transmit light contingent upon their temperature. Cool items emanate essentially long wavelength light Hot articles radiate principally short wavelength waves The Physics of Light

Slide 5

Objects transmit light contingent upon their temperature. The Physics of Light Cool articles discharge essentially long wavelength light Hot items emanate basically short wavelength light. Human Electric Stove Lightning Bolt Spot Light Red Light 4,130° C (4,400 Kelvin) Ultraviolet Light 30,000° C (30,273 Kelvin) Infrared 33° C (306 Kelvin) White Light 5,230° C (5,500 Kelvin)

Slide 6

The Range of Infrared Light Infrared light lies just past the red segment of the unmistakable range ("below red"). Infrared wavelengths are around 0.7 to 350 microns. (a micron is one-millionth of one meter, or around 1/50th the width of a human hair). Close Infrared Mid Infrared

Slide 8

Getting the WHOLE picture An item can look fundamentally changed contingent upon the sort of light gathered from it: Since not long after Herschel found infrared light space experts have been watching cosmic articles in Infrared Light to get a more finish picture Visible Light Image Mid-Infrared Light Image

Slide 9

Why Study Infrared? Unmistakable: dim cloud, intensely darkened by interstellar dust ("Horsehead Nebula") Near-Infrared: dust is about straightforward, inserted stars can be watched framing Mid-and Far-Infrared: shine from cool dust is specifically recognizable Visible Near Infrared Mid-Infrared

Slide 10

Why Study Infrared? Cool items - like recently shaping stars and heavenly bodies - transmit only in the Infrared

Slide 11

Why Study Infrared? Infrared infiltrates interceding dust mists, permitting us to see through or into them Visible Light Infrared

Slide 12

But there\'s a Challenge... Earth\'s climatic water vapor retains all approaching infrared radiation Even peak observatories get a constrained perspective of the infrared universe Infrared telescopes need to see from high height or in space
