For those of you who think that stars should easily be seen from the lunar surface in daylight, I have a simple, straight-forward question:
How much brighter would stars be on the lunar surface than on the Earth's surface?
I don't need an exact number; a ballpark guess will do.
Twice as bright?
Ten times as bright?
Fifty times?
A hundred times?
Give me a rough number, please.
How old are you?
If the answer www.youtube.com... from the astronot-actor Armstrong did not satisfy you,
maybe you can ask your school teacher?
Let us know the results so we can compare them with NASA educational outreach programs.
Can you see more stars from the Moon?
On the Moon, there is no atmosphere and no clouds to blur or block our view of the stars. The sky on the Moon is always black, even during the daytime. From the Moon, you would be able to see many more stars than you could see from Earth. You would also see the Earth in the sky, and it would appear much larger and brighter than the Moon appears to us. Earth would also go through phases, like we see the Moon do from Earth. Many astonomers think that the Moon would be a great place to have an observatory.
Compare these NASA answers for kids with the answers of Mr. Armstrong for journalists:

Omg... are you serious? Of course moon would be an ideal place for an observartory. During night. Apollo was there during daytime. I'm reluctant to believe that you don't understand what that means. If that is really the case then please spend some time outdoors or something.

Considering that there is no light pollution, no athmosphere to scatter starligth etc. I think you would see more stars on the sky. However since there is no athmosphere they wouldn't appear as big as they do on earth.

Stars would have been an undeniable evidence for everyone to know that the missions that landed men on the moon were genuine. Photo and movie records would have been measurable for distances and magnitude.

While you are at it, explain why you posted while blithely ignoring all of this stuff, which was covered comprehensively earlier in the thread.
Visibility of stars from the Lunar Module
103:12:44 [Neil] Armstrong (Apollo 11): "I'd say the colour of the local surface is very comparable to that we observed from orbit at this Sun angle—about 10° Sun angle, or that nature."
103:22:30 Armstrong: "From the surface, we could not see any stars out the window; but out my overhead hatch (means the overhead rendezvous window), I'm looking at the Earth. It's big and bright and beautiful."[1]
vs
[Alan] Bean, from the [Apollo 12] 1969 Technical Debrief—"Star (and) Earth visibility was interesting. We could always see stars at the upper rendezvous window."[1] The Sun is currently 5.5° above the eastern horizon.[1] With the Sun 10° above the horizon, stars should have been visible out the Apollo 11 overhead window too.[1]
Visibility of stars from the lunar surface
[Neil] Armstrong (Apollo 11): "We were never able to see stars from the lunar surface or on the daylight side of the Moon by eye without looking through the optics."
[Michael] Collins (Command Module pilot): "I don't remember seeing any."[1](1:06:00–1:06:19) (Collins' remark is misattributed to [Edwin] Aldrin in the transcript.[1] In his book "Liftoff", Collins writes "My God, the stars are everywhere, even below me. They are somewhat brighter than on Earth")[1](p. 33)[1]
Alan Bean (Apollo 12): "Oh so carefully, I removed my silver pin, took one last look at it, and gave it my strongest underarm toss out towards Surveyor. I can still remember how it flashed in the bright sunlight then disappeared in the distance. It was the only star I ever saw up in the black sky, the sunlight was just too bright on the Moon's surface to see any of the others."[1]
Stars are not readily seen in the daylight lunar sky by either the human eye or a camera because of the brightness of the sunlight surface.[1]
vs
103:22:54 Duke: "...Gene Cernan says that, while standing in the shadow of the Apollo 17 [Lunar Module] (LM), he could see some stars while he was outside."[1] (Correction on the star visibility issue from the Moon is introduced later.) Astronauts' reminiscences contradict the descriptions of the star sky observed by Soviet cosmonauts (Leonov, Lebedev, Savinykh) on the dayside of the orbit; light from the Earth (Earth albedo 0.367, Moon albedo 0.12) did not hamper them see the stars.[1] For example, Leonov says that "the brightest of the stars can be recognised when they are farther than 30° away from the daylight luminary [the Sun]".[1]
On the Moon, the sky is black—even during the day—and the stars are always visible.[1]
In fact, the Moon is about the poorest reflector in the solar system... The Moon reflects only 7% of the sunlight that falls upon it.[1]
