Can we have some pictures of other planets outside our solar system? Are there any really good ones?

As far as I know...there are other planets...but we don't have good pictures of them...hell we barely have a good photo of Pluto so we don't have pics of other planets...um...but I think some Nebula pictures would be cool...just suggesting...

Are you referring to such "nebulosities" as M47 in Orion, or the Ring Nebula or such? I think our club has some; I'll see what I can do. I can also scout out some astronomy sites and bring pics here from other places if you want....

Oh yes, we do not have any pics of any planets outside of our system. They are too far away.

I have seen the best picture we have of Pluto and Charon(sp?) and I'm wondering how they got as much info as they have from it...They look like 2 bright dots...I don't remember the name of the artist but he is an astrnomer and he did some painting of how a planet would look like if you were on it...my astronomy teacher really liked it..I'll get the name of the guy from him.

Bob: we can extrapolate the nature of a planet by its reflectivity as well as by sending satellites behind it, then analyzing the spectral shift of the light these satellites emit as this passes through the planet's atmosphere; its rotational velocity using redshifting or blueshifting of light, and its period of revolution around the Sun using Kepler's Third Law. Knowing the period (and from this, it's orbital "width") we can determine its mass. We can also determine its general temperature by determining it's albedo, (that light reflected, not emitted from the planet)~ once this is known, we then know it's true luminosity, and can calculate how much heat there ought to be to make it as bright as it is.
