@xKingPola3ux: The reason we can see more in those wavelengths are twofold: We get redshift due to the expanding universe and the great distances, so most EM radiation moves to longer wavelengths. Things that are very, very distant have no more radiation inside the visible spectrum, it's only infrared left. The second reason is due to materials absorbing different light.
@xKingPola3ux: Excellent questions. First, "back and forth" is sound waves (compression), but electromagnetic (EM) waves are more similar to "increase, decrease in energy" (even though that is still inaccurate). Secondly, we can only see visible light since our atmosphere stops most other frequencies, so almost nothing from those are leaked down to earth. Since only part of the spectra is present around us, we only evolved sight for that subset. This is why we want to have telescopes in space.
@xKingPola3ux: If we're talking about "seeing" as in taking a photo, it's just due to how you calibrate the light sensitive parts of the camera / the film. We often see infrared due to heat and almost anything casts of infrared. Have you ever seen a black-and-white movie taken during the dark (aka "Night Vision")? That is infrared. You should read up on "Black Body Radiation" for more insight in this.
Stunning pictures like every time... And wow, there are even stars INSIDE the observatory (2:50+) ;-) Someone with less imagination would call them hot pixels on the CCD. Unfortunately I know them very well, because my digicam always captures the same "fixed stars" in every night shot.
@xKingPola3ux: cont... If you know why objects have color you know the principle. Sometimes, an object has the "color" of "infrared", and sometimes there is a cloud of gas in the way that absorbs almost everything. Think about it. Your walls stops all visible light, but radio waves passes through from your wireless router without much effort. This is the same thing. Hope this cleared things up for you. :-)
@cdholder18 I absolutely love this part of your comment: "just look at viruses and cells microbiology basically, and that will defeat any and all religious dogmas." Thanks!
Humans are social creatures. Social events and music are not worthless, they are the fruits of our creativity and intelligence just like science and technology are. I was referring more so to the things are are destructive to humanity, the obvious example being war. See MythicSun's comment.
Orion nebula is made by sulfur,carbon dioxide and hydrogen that is impossible to be imagined and captured by human imagination to the amazing universe.
"A group of very hot young stars, pumping out fierce UV radiation that is clearing the surrounding region and making the gas glow." Some night at the disco, eh?
What you are talking about is essentially genetically engineering the species. Our technology is still a very long way off from that, and of course there are an array of ethical concerns involved, but I'd want to see a concrete situation to cast an opinion. Photosynthesis is not a single or even several gene process. At this point suggesting humans that can photosynthesize is like saying humans who can, say, live without oxygen, or divide asexually on their own. Sci-Fi, basically.
4 people are christians who still think that we're the dead center of the universe and the only thing within it that matters. (X)amount of the 444 likes are mormons and are scouting potential real estate.

@xKingPola3ux: Wavelength. It's the only thing that differs infrared, microwaves, radiowaves, visible light, etc. from each other.
That's awesome! What a view!

Please tell me they named it VISTA before Windows Vista.

Orion nebula is the most spectacular nebula ever in the milky way galaxy.Orion nebula produce more new stars with cloud made by carbon and oxygen.

is the quy talking from South Africa?? :))
they already are working on telescopes much more powerful to be put in orbit.
On second thought, at least they didn't call it the iPad...

I think theyre gonna be fancy and spell it 53v3n
What are they gonna name the next telescope? Seven?
I wonder if the telescope was preserved in the earthquake...

cool
They really need to upgrade... I'm thinking Windows 7.
Vista is too small. lets go Bigger!
Ok but where the view from the actual telescope. This is just cgi and bad cgi at that. Oh wait you showed a 5 second clip of the actual at the end
lol
Convince your politicians to spend more money on science. Scientists will go as big as society allows them.
