Yes, Ladies and Gentlemen. This *is* a question on a "Homeland
Security" test for the Federal Government.

Even TV, Stage, and Movie stars have to twinkle evey once in a while, even
if they don't drink a lot of water. Just like us regular folks in that
respect.

I think that you mean "tinkle".

The question should be: "Why do stars twinkle, but planets do not twinkle"?

You obviously don't live under the jet stream in the Colorado mountains.
The planets twinkle all too often here.

For some reason i rarely seem to see stars as twinkling. And my seeing =
is quite poor being just east of a 10k foot mtn range. I also don't tend =
to see colors in most stars. On the other hand i CAN see quite faint =
objects. Just peculiarities of my eyes i guess.

The reason you don't see the stars twinkling and lack of color in poor
seeing is because the jetstream winds above you are blowing hard and steady.
Planets would be totally blurry in a telescope, lack color and definition,
but wouldn't be bouncing around like they do when seeing is poor, but slow
oscillations of the winds (varying speeds high above).

It may also be how you are looking that effects this.

The center if the human eye only sees in black and white, the color
receptors are in a ring surrounding the center. Because of this, it's
sometimes better to look to the side of an object to better discern
the colors in it.
