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
Spectrum of Waves
Radio Waves
 Microwaves
 Infra Red
 Visible Light
Spectrum
 Ultra Violet
 Gamma Rays
 And X-Rays

Visible vs. Non-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
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.
Visible Spectrum

Non-Visible Spectrum

The Non-Visible Spectrum, Includes;
Radio Waves
 Microwaves
 Infra Red
 Ultra Violet
 X-Rays
 Gamma 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.

Microwaves
Microwaves are all around us
 You use them every day with your;

cell phone
 Microwave
 and any other wireless transmissions


Microwaves are isotropic, what this means
is that they are constant and surrounding
all of us all the time.
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
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.
Spitzer Satellite
The Helix Nebula from Spitzer
(Infra Red)
Vs. The Helix Nebula from Hubble
& Blanco (Regular Light)
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
Compare the ultra Violet of
Andromeda with the Visible Light
X-Rays

X-Rays of Galaxy NGC 4697 vs. the
fuzzier optical image
Gamma Rays
This is an image captured in
Gamma Rays by Fermi.
Fermi is a Gamma Ray Detector.
Compton Gamma-Ray Observatory
False Color Images

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”
Milky Way
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.
