When we go BACK to the moon again in the near future, everyone on Earth will be able to watch on TV, as people again walk on the surface of the Moon. Do you realize just how "cool" that is? Do you look forward to watching it happen with your own eyes. (In case you missed it in the late 60's and early 70's) NOTE : If you are part of the delusional minority that thinks we were "never actually there"...Please don't bother answering this question. WE WERE...and will be going back again relatively soon.

c. These stars are so cool that nearly all of the electrons in the hydrogen atom are in the ground state.
d. Stars of this temp are too cool to produce an absorbtion spectrum
e. Stars of this temp are too hot to produce an absorbtion spectrum

Recently, on some nights there is a yellowish light visible in the western sky at night. It seems a bit bright to be a star, or possibly too close to the Earth.

I live close to Gulf Shores, Alabama, if that helps. The object is not visible every night. I haven't studied it in length, but it is visible shortly after the sky is completely dark and the stars become visible.

It is no longer to be found when I go out again (usually after 10-11 PM). I thought it might be a planet, because it doesn't appear to move.

WOULD YOU PURCHASE LUNAR SPACE STATION BONDS TO FINANCE PRIVATE SPACE EXPLORATION?
I do not have any for sale, just asking a hypothetical question.
I would if they were available. Would you invest in a bond issued in a private corporation that was focused on space exploration? What about to fund NASA?
Regardless, if it were a typical rated bond giving a good 1.5% return or something like that over 5-10 years, would you consider that investment?

I was in my brothers room looking at a cool website and from no where we heard a high pitched whirling noise just above the roof. Me and him were startled my this noise so we opened up his blinds to see a large T shape object with lights all over it speeding up at a 180o into the air and the lights got smaller and smaller until it got to small. I really do know what i saw and i'm now scared because i have read of other cases were people have been abducted from this noise above thier roofs. who can i phone to report this incident?
