I mean when measuring in 'light years' for instance, when they are looking through a telescope how can they tell how many 'light years' something is away....
Complex stuff if you ask me
But the zoom and magnifactionof the lense.
Don't forget, the "photo" is probably 1 of about 10,000 bits of data they get from the telescopes. They mainly measure particals, what the dust clouds are made up of, infra-red, and a hole host of things they study I couldn't have the first clue on understanding. They do a LOT of work from the images.
Most pictures that come out of the telescopes are usually not colour photos.

See this shot for example.

Wow thats well cool!
Is it the same part of sky just at a different time, or is it from in space and just added to the pik?

You can get shots like that from earth with a camera and a mount that follows the rotation.

Intricate, glowing nebulae that shine in planet Earth's night sky are beautiful to look at in deep images made with telescopes and sensitive cameras. But they are faint and otherwise invisible to the naked-eye. That makes their relative location and extent on the sky difficult to appreciate. So, consider this impressive composite image of a wide region of the northern winter sky. With a total exposure time of 40 hours, the painstaking mosaic presents a nebula-rich expanse known as the Orion-Eridanus Superbubble above a house in suburban Boston, USA. Within the wide and deep view are nebulae more often seen in narrower views, including the Great Orion Nebula, the Rosette Nebula, the Seagull Nebula, the California Nebula, and Barnard's Loop. The familiar constellation of Orion itself is just above the foreground house. Brightest star Sirius is left of the roof, and the recognizable Pleiades star cluster is above the tree at the right. A version of the big picture that includes simple constellation guidelines is available here.
Basically, its whats up there, its just due to light pollution, gasses in the sky etc, we can't see so much down here.
I've seen our milky way though in a very very quiet part of france which was dark all around. You could see our milky way belt going from lower left to upper right of the night sky. Looked like a huge areoplane flume out the back, but much MUCh larger, and with stars in it. Amamzing sight!
I gotta go see the northen lights during my lifetime as well!!!!

Apparently there is 2.5x10^89odd particles in the universe, particles as in proton, electrons etc thats....
250000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 particles

And the worlds more worried about war, and owning land than trying to put resources into finding out whats out there more.
Mad aint it....

What are your views on other lifeforms similar to ourselves, millions/billions of light years away. I think there must be something else out there somewhere tbh, very weird when you take the time to really think about it.

There are 2 ways to think about it, either we are extremely unique and the odds of another planet like ours that can support life existing are extremely small, or the theory that it's not that difficult and there are so many places it could happen.
Both have convincing arguments.
I'm going for there are loads out there.
Partly because, although amazing in the scope of the solar system, life here isn't that amazing in the scope of the time and distances of the universe and partly because I like Star Trek

I find it strange to think that, if there is places similar to earth; what is it like, their existance, technology, inventions etc etc. We have amazing things on this earth but there might be other places that are far superior to us.

See that annoys me, as its only based on a planet that could support life as we know it. Their is nothing to suggest its not possible for a totally different life form from what we know to survive on a foreign planet totally different to our own.

true there could be things that swim in boiling acid.
Think this though, an intelligent being that could be millions of years ahead technology will be "out of this world"

I agree.
From my limited understanding of what the scientists understand, to have anything even remotely close to what we currently consider life there have to be certain conditions, even if that life isn't exactly like on earth.
Afaik this is what the talk of odds is based on.

Yeah, I know they base it on similar attributes to our own (i.e. water and oxygen is needed iirc). But that totally ignores that their could be an alien life out there that can breath (if they even have to breath) methane and shits oxygen - for example!

I think that's taken into account, even then there are still some pre-requisites.
There's a good chance I've not got it correctly and an even bigger chance there could be something totally different out there anyway.

Whatever is out there, I know they'll be less advanced than me anyway.

Two pics from the upgraded hubble telescope
I wonder what sort of pictures the new space telescope will bring when thats launched!
