That's amazing... it is hard to beleive pictures like this are real, it just looks so... science fiction...

Well, they are real, but we might not be able to see them like this with the naked eye. Hubble uses filters etc, that gives the final result like this.

Yup, Hubble needs to get loads of thanx. Most of the stuff Hubble produces is amazing.
Just a bit of info on how Hubble creates images:
Hubble doesn't use "film", but it's camera's rather record light by means of special sensors. This produces an image in shades of black and white.
The color images that is so awe-inspiring are actually a combination of one or more of these black and white images, to which color has been added during processing.
The reason color is added varies: to simulate what an image would look like if we could see it with the naked eye, to enhance an objects detail, or to see something that normally wouldn't be able to be seen by the human eye.
Lets take the Mars (Mars1) image for example. First black and white images are recorded using filters to capture red, green, and blue light respectively being reflected from the planet. During processing each black and white image gets assigned it's color, red for the red light image, etc. The images then get combined to create a full color image. In the case of the Mars image, the colors were used to depict the natural colors of Mars.
The end result - an amazing shot of what awaits us "out there".

Hoho! Are you a "space" student? ;-)
When will come the new generation of space telescope? I think Hubble is at the end of its life now...

LOL. Nope I'm a IT student. Not much going for astronomy here in SA... (work wise). No space agency here. I do have an interest in astronomy and it's a hobby which I'm starting to give a bit of attention to again.
The new generation of space observatory will be here in 2004. SOFIA... it's not a stationory orbiting telescope, but rather a telescope built into a boeing type aircraft. According to estimates, it will be much more powerful than HUbble, but it will only function using Infra-Red. I don't know much details about it though... just heard of it a few days back.
And I've just read that NASA is busy constructing another new telescope "James Webb Space Telescope" which will be launched in 2011. It will be used to see the first stars and galaxies that formed billions of years ago. Should be pretty impressive!

I like the single star in the middle. It adds a lot of distinction...it looks fake.
