Re: How do you know?

As Percy has adequately pointed out, this image of some "unknown white circles and dots" is not "computer generated"
I never said it was!

quote:
You say that all WFPC2 images are "transformed" - have you considered the fact that the light and its resultant image which is forming on your retina right now is being "transformed" by your brain into an understandable format?
Yes I did. But that is now going into philosophy. Please stick to astronomy. Tell me, do you know what the function mkobjects does?

quote:
Is there some way each dot is absolutely, demonstrably shown to be a galaxy? Maybe... I don't know. But if you are putting forward the proposition that they are not galaxies, then what would you suggest they are?
I have no idea what they are. I never claimed I knew in the first place. I'm just saying that nobody knows what they are. And that those final images we see are actually an assumption of what "should" be there is the universe is homogeneous and isotropic.

This post has been revised in light of newly uncovered information.

I've uncovered additional information about how the simulated images were created at New Instrument Package to Expand Space Telescope's Vision found at the HubbleSite and have revised this post to incorporate this information.

Smooth Operator writes:

No. There is only one type of WFPC2 camera, and it is the WFPC2 camera. The new one will be called ACS.

That's correct. There's the old WFPC2 camera, and there's the new ACS camera. And before the ACS camera was installed NASA produced some simulated photographs of how the two would compare. They are illustrations, artists conceptions. The WFPC2 picture is on the left and the picture from the yet to be installed ACS camera is on the right:

See the picture with the irregular outline on the left? That's the WFPC2 simulated picture. Possibly it is based upon a real photograph, but if you go to this list of release images you'll see that it and others are all labeled "Artist's Concept."

See the large square picture on the right? That's the artists concept of what a photograph of the same region of space from the ACE camera was expected to look like.

This was all described in the caption at Advanced Camera Will Give Hubble a New View of the Universe:

Article from redOrbit writes:

This is a simulated image of how the universe will look through the eyes of a brand new camera for NASA's Hubble Space Telescope. The Advanced Camera for Surveys (ACS) will offer deeper, wider and faster views of the heavens than the current generation of cameras on Hubble.

For comparison, these simulated images show a distant, massive cluster of galaxies as seen by Hubble's current imaging camera, the Wide Field Planetary Camera 2 (WFPC2), and by the ACS's Wide Field Camera.

The caption's language is a bit ambiguous in one way. Where it says "This is a simulated image" they actually mean both images are simulated. And by "simulation" they mean "artist's concept." Probably the artist used a computer to create the images, but neither article says. While nothing I could find was specific, it is possible that the technician began with an actual photograph from the WFPC2 camera, or at least based his illustration on an actual photograph.

It should now be clear to you that you have misinterpreted what you read. That image was an artist's illustration of how much better the ACS camera would be than than its WFPC2 predecessor. The image was not the product of the process by which actual images from Hubble are produced.

About the rest, I acknowledged your unusual views earlier, and you're welcome to them. There are people out there who can't be convinced that they're not Napoleon Bonaparte, but that doesn't mean they're really Napolean Bonaparte. Apparently you can't be convinced that combining images made at different wavelengths is perfectly valid, but that doesn't mean it isn't actually valid. By the way, making color pictures by combining intensities at different wavelengths is how color TV's work. Each pixel is actually three dots of color, one red, one green, one blue.

LOOOL! I misinterpreted it!?

No, you, are the one who misinterpreted it.

AND IF YOU ACTUALLY READ MY FIRST POST THAT DISCUSSES THAT...

Yeah, if you only read it, you would have known that. You would have know it, because I quoted the part where it says that it's a simulation.

And you still didn't answer my question. What does MKOBJECTS stand for!? What does it do?
