The Hubble pics are amazing, that's for sure. They are beyond amazing. They are what is known as Virtual Reality.
The Hubble is actually a big mysterious hunk of junk floating up in space, more of a computer than a telescope. It is difficult to operate because you can't get near it, and it's more for show than anything. It can't even take a decent picture of the moon. There's a thread running here right now about backyard telescopes that take better pictures of the moon than the Hubble does. www.abovetopsecret.com...
But because the Hubble is "up there" the virtual reality pictures we're told it's giving us seem to be so special and believable and wonderful because they're coming from this thing floating up in space, even if it's only 100 miles up, and even assuming we can even believe any of these pictures NASA is feeding us are even coming from the Hubble at all. Furthermore, once these images are produced they are prettied up by graphic artists such as Calvin Hamilton, who you can thank for almost all the photos that are put up on NASA's website and all the fancy NASA space posters you buy in the Space Museum.
In addition to the backyard telescopes currently being discussed on ATS, we also have another VLT (very large telescope) in Chili that takes way better pictures than Hubble does, has far greater resolution, and produces pics that are not so much virtual reality.
Since Hubble is really a big computer floating in the sky we need to remember that it's data in, data out. If you put garbage in, you get garbage out. The images are based on computer data that's put into the Hubble, telling Hubble what it would see if it could see but it can't see. Who are the ones putting the data into Hubble? NASA "scientists" who have agendas, who are very biased in their beliefs, and who need people to support them so they can keep their jobs working for the same agency that faked the moon landings. The NASA "scientists" have extremely vivid imaginations about how things work in space and/or have sinister agendas for the NWO.
In light of these things, would there not be a temptation to contrive images to support agendas or at least to promote and foster the idea in the taxpayers' and voters' minds that NASA has super capabilities to discover things about the wonders of space, super capabilities that in fact NASA does not have at all? If the American taxpayers think NASA is discovering amazing things beyond the imaginations of anyone, then might they not continue to fork out billions to keep NASA busy roaring around in the Shuttles and their other romantic adventures?
I don't believe Hubble can produce accurate images of deep space because the Hubble images of the moon are so poor. As a telescope, Hubble is a disaster. If Hubble does such a poor job as a telescope, why should we trust it more as a computer to show us the virtual reality of space? A computer is only as good as the information that's fed into it.
NASA's budgets are being cut because Americans are tired of paying for space shuttles that crash and pollute the atmosphere and cost too much money. Therefore, NASA needs any kind of public relations boost it can get. These mysterious Hubble pics pique the interest of the public and help to keep the tax dollars flowing.
Therefore, why should I want to trust the Hubble pictures?
Answer: I don't.

The Hubble cannot see things that are nearby very well. It's far-sighted. That means it lacks the "ability to focus on near objects," such as the Moon. Backyard telescopes, on the other hand, are not. They cannot bring in images of the far away stuff, as where Hubble can. You're comparing apples to oranges there!
We stole the following off a NASA discussion board. We would usually just link to it, but discussion messages have a habit of expiring and this was too good to lose. Ed Cheng explains there's a law of physics that would prevent Hubble seeing the Lunar Module, and it's to do with the size of its light collecting mirror.
The wavelength of visible light is around 550x10^-9m (i.e. very very small).
The diameter of Hubble's mirror is 2.4m.
Highest ever physically possible resolution = 1.4 x 550 x 10^-9 /2.4 m = 3.2 x 10^-7 radians
At a distance of 350,000km this works out as about 124 metres. As Ed says, roughly the size of a football field.
So even if Hubble's camera had a greater resolution, it still couldn't see the Lunar Module.
But doesn't this same Hubble take photos of things billions of light years away? Yup.

It is true that the Hubble Space Telescope can see things very clearly -
one can argue that it provides the clearest view of the sky in visible light
"colors" that humans have ever had. However, its capabilities are still
limited by the laws of physics.
For a telescope with a circular collecting area of diameter D (2.4 m for
Hubble), the smallest feature that one can resolve at wavelength L
(550 x 10^-9 m for visible light) is given roughly by:
resolution = 1.4 L/D = 3.2 x 10^-7 radians
This estimate gives the "diffraction limited" resolution, or the resolution
based on light's wave-like characteristics. It is difficult to improve
upon this limit.
The distance to the Moon is roughly 240,000 miles. Hubble's resolution
corresponds to a physical dimension of
size = x = 0.08 miles = 405 feet = 124 meters
at the Moon's surface ... roughly the size of a football field.
This is quite a bit larger than any of the artifacts you would want to see
on the lunar surface, so even Hubble's tremendous clarity is not enough for
what you would like to do! If we had an aircraft carrier at the lunar
surface, then Hubble could probably get a pretty good look at it.

I dont know if this is true but I think I remembering hearing that some pictures taken by the Hubble are nottrue colors pictures
If that is true wouldnt they be "fake" to some extent? Not that the object is not really out there just thats not how it would look to human eyes.

Enhanced is the word not 'not true' or 'fake'. The reason is that NASA feels that the public won't be satisfied with the original images and that they need to be enhanced.
