Imaging Space I believe that If we look somewhere hard enough, we will find something… Presentation by Emily Bowers

What is out there? The Electromagnetic Spectrum “To start with you should know what a spectrum is: when white light is shone through a prism it is separated out into all the colours of the rainbow; this is the visible spectrum. So white light is a mixture of all colours. Black is NOT a colour; it is what you get when all the light is taken away.” –Purchon.com

Visible vs. Non-Visible Waves Visible waves Visible waves Objects that we can see with our own eyes in the visible part of the wave spectrum, otherwise known to us as normal light waves Objects that we can see with our own eyes in the visible part of the wave spectrum, otherwise known to us as normal light waves Non-Visible waves Non-Visible waves Other types of waves within the spectrum that we as humans are unable to perceive with out some kind of assistance, for instance; X-Rays.

Radio Waves Scientist are able to pick up radio waves from different parts of space, these are the longest wave in the electromagnetic spectrum, and it as such, has the highest frequency.

Any amateur with a transceiver can also point it into space and find some radio waves to listen to; right from their own backyard.

Microwave Background This is a WMAP Image of space “Wilkinson Microwave Anisotropy Probe”

Infra Red “These radio/light waves have a very short wavelength; their wavelength is longer than visible light. Infra-red can be detected by special infra-red film.” -Purchon “These radio/light waves have a very short wavelength; their wavelength is longer than visible light. Infra-red can be detected by special infra-red film.” -Purchon

Infra Red Images from Space Galaxy: Messier 81 These are multiple infrared photos of the same galaxy, in the top right corner there is the visible light spectrum of the same gallaxy.

Visible Light Spectrum

Hubble Space Telescope The Hubble Space Telescope produces the visible light photographs from space with out atmospheric interpherence.

Visible Light Photos captured by the Hubble Telescope Carina Nebula in visible light

Hubble takes first photo of a planet circling another star:

Ultra Violet These waves have very high energy and very short wave lengths; shorter than visible light. - Perchon These waves have very high energy and very short wave lengths; shorter than visible light. - Perchon

Compare the ultra Violet of Andromeda with the Visible Light

X-Rays X-Rays of Galaxy NGC 4697 vs. the fuzzier optical image X-Rays of Galaxy NGC 4697 vs. the fuzzier optical image

Gamma Rays Compton Gamma-Ray Observatory This is an image captured in Gamma Rays by Fermi. Fermi is a Gamma Ray Detector.

False Color Images Many images are created with false colors to emphasis a particular importance. Many images are created with false colors to emphasis a particular importance. “This is a visible light image of the planet Jupiter. It is in false color - the colors were chosen to emphasize the cloud structure on this banded planet - Jupiter would not look like this to your eyes”

Conclusion I have discovered many great things about both visible and non-visible waves that we can see objects in space with, I hope that this has helped you to appreciate all that our growing technology has to offer us in our quest to find more growth and activity in the heavens.
