Looks like Homer Simpson eating a donut.
Ringworld!
What proof do you have that Hubble cant take color photos?
Well, colorized by the astronomers. They take three or more exposures through narrowband filters, some of which are for wavelengths shorter or longer than we can see. Then, they choose visible colors and assign them to the resulting images and superimpose them, giving the dramatic chromatic effect.
To the human eye (through a powerful enough telescope), they tend to look gray and white.
See my post following yours. I should add that the Hubble CCD sensors have natively wideband response and very fine resolution.
Making a color-sensitive CCD array, or set of arrays, would not be the best available use of the total sensor area; making it wideband (infrared to ultraviolet) yields the best tradeoff between high resolution and high sensitivity. This is especially true considering that they want to observe a greater variety of wavelengths than any traditional color imager could provide.
Instead, they make the whole array sensitive to one strategic wavelength (actually a narrow band of wavelengths) at a time by putting one of several available filters over it. Some of these wavelengths are in the visible range, and some are outside.
lol
Cause I sent similar photo’s around before and was corrected. See post 24.
I wish it would look like the photo’s however.
Oops, forgot the number the second two.
“Starwomb” baby is #47
Human skull #17
I stared at the photo for about 20 minutes and I think I see a puppy..........
