Look what a kewl application! checking out the universe in different wavelengths can be - at least visually - really interesting :

http://www.chromoscope.net/

Too bad i just couldn't find any explanations of what each different wavelength shows e.g: infrared shows changes of temperature so what is brighter in IR is probably hotter - but how do we read the other ones? Anyone has an idea?

Some wiki knowledge on the subject, for the ones with a passion for astronomy :D

Gamma ray

http://en.wikipedia.org/wiki/Gamma-ray_astronomy

- celestial events such as supernova explosions, destruction of atoms, black holes and even the decay of radioactive material in space

X ray

http://en.wikipedia.org/wiki/X-ray_astronomy

-X-ray emission is expected in sources which contain an extremely hot gas at temperatures from a million to hundred million kelvins.
(the universe is hot, huh?! :D)

H alpha

http://en.wikipedia.org/wiki/H-alpha

http://www.prairieastronomyclub.org/halpha.htm

- convenient for solar observations. The H alpha line is universally used for patrol observations of solar
flares, filaments, prominence s, and the fine structure of active regions.

hmm...i don't quite get how we can use this info to understand the Milky way image :P

Microwave

http://en.wikipedia.org/wiki/Microwave#Radio_astronomy

http://www.astronomywa.net.au/education/astronomy-primers/34-different-types-of-astronomy/136-microwave-astronomy

Waaw: . Microwaves are useful, as they allow us to look at what the universe was like right at its birth.
As microwaves are hard to observe from the ground, space-based telescopes are used. There have been a number of probes launched to map the entire sky in the microwave band

Maan, the things that humans do and we've got no idea!!!!

wow! that's so very cool! ilike the visible and the 2 below red modes... i'm officially happy to be seeing in the spectrum i am seeing: tis' very cool! I like the swirly forms possibly better... but then again this spectrum allows for beautiful flames too :D super awesome!!! it's fascinating to think about what else may be around us. I like for example Terry Pratchett's ideas of seeing cities like huge mushrooms on the planes, or Frank Herbert's idea of suns being these really big beings... my point being is like we don't know about all these layers of reality what if there indeed are many layers of things overlapping our own, we just don't very much perceive them. It might even click with some ideas about the spirit world...
Great find!

The amazing thing to me is that it might be the most powerful microscope in the... universe :D
