With such images available, where do I go to view full HD pictures of the moon?

Those pictures are worth a million bucks. It is really neat to see a picture of earth from there. When I say a million bucks, I mean cost S&F I wonder if they doctored the rings image?

Eerily amazing.

We really are... nothing.

As with most NASA images, they are composites and touched-up. They are "hardly" doctored.

As well some of the most stunning images we get aren't even taken with cameras, they are radio frequencies and thermal images and composites blended into really beautiful images.

Sadly, when it does become within our ability to go see these places with our own eyes, we won't see half of the beauty.

Nice post OP.

It truly is mesmerizing.
And to think we are all alone :/

There isn't such satellite for that. Satellites are not for entertainment, but research. Making satellites is expensive, that is why there is so few.

Best is Lunar Reconnaissance Orbiter, but it isn't very HD. It takes images like this:

Wrong, the Lunar Reconnaissance Orbiter provides great hi-res images of the Moon. lroc.sese.asu.edu...

There's only one thing lacking in those images - colour. The Moon isn't utterly black&white, there are subtle colour variations depending on mineral makeup of the terrain.

Raw images are rarely suitable for public releases (although they are made public at sites like saturn.jpl.nasa.gov... ), so there is almost always some editing and photoshopping wizadry involved. For example, for this image, they combined the rings from a low-exposure shot like this one, and the Earth and the faint outer rings from a long-exposure shot like this one. There's also the issue of alignment of the rings and the Earth from frame to frame, due to the fact that Cassini moves some distance between taking pictures. Based on my experience on making my own colour composite of this image, NASA had to align the rings and Earth in separate images, then combine them together.

Anyhoo, it's not what I'd call doctoring, but rather using various techniques to overcome technical issues (like exposure, alignment, digital noise, cosmic particle streaks) and presenting a nice-looking picture to the public. Everything you see there is real, and similar to what you'd see with your own eyes (despite what GaryN says).

and still can't get high res color pics from mars ..

awesome ..

Still making those idiotic claims!!

Very Cool! Saturns rings look pretty awesome there as well! What's up with the outer one made out of light?

It is the so-called E-Ring. Actually, it's more like a torus (donut-shape). It's formed from the ice-geysers on Saturn's moon, Enceladus, which orbits right in the middle of it..

How cool is that?!

I didn't know the earth emitted that much light

Someone in another thread was questioning the size of the moon being to big..
I thought it was due to sun glare, so I removed the glare.. and got a picture that mach the scaled as we know it.

just wanted to share it here also

NASA has uploaded some higher resolution versions of the rings and Earth picture. The resolutions are from 800x600 up to 1920x1080 (suitable for desktop wallpaper).

They also describe the image, and how they took it:

Just incredible pictures all around. And I find total beauty in Saturn's outer rings, they almost look fake to me... Does anyone know the thickness of the rings of Saturn? The pic got me wondering...

It brings a question to my mind though...

If Saturn is so big compared to earth,
then why doesn't Saturn appear bigger in the nights sky?

The tiny blue dot is still visible as a planet really from the pic,
and small compared to the size of Saturn.

Atmospheric interference?

If you look at an orbital map of our solar system, you'll see that Earth, Mars, Venus and Mercury are really in in the inner suburbs, while Jupiter, Saturn, Neptune and Pluto are way out in the suburbs and cottage country. It's really just a matter of distance and size.

One photographer did imagine if our Moon were replaced with any of the other planets:

sorry ..

I'm not buying this .. there's something obviously missing in this picture .. especially when the pic is able to zoom in at that distance ..

What happened to the last post on this anyone know? I came back and it was 404'd?
