why is not a single star visible in the astronauts moonwalk videos???

[neelam]

hi guys i want to know that when we see the videos of different astronauts repairing or spacewalking then why cant we see millions of stars in the background or why can we see the milkyway trail??

there is vacum and no light pollution or clouds etc then why are those HD cameras incapable of showing stars whilst if we point a HD camcorder towards stars from earth we can capture some star activity but why does every thing vanishes in the space?

why dosent an astronaust takes canon 100d with him and captures the milkyway trail through the window ??

My take on this is that to capture the faint light from stars you need long exposures in order to make them appear on the photo.

When the astronauts are taking photos of, for instance, them holding the flag, stepping down onto the lunar surface they are just using normal exposure lengths that pick up bright, normal images - but are not sensitive enough (or long enough) to pick up the fainter stars in the background.

I think this may relate to a video scenario too. Just been reading the link Gaz posted as I've been typing this up, looks pretty good, give it a read

(someone if I am wrong on this please put me right!)

Because the entire space program was filmed in a studio back-lot in Texas.

You'd be surprised how many people believe this

Hmmm, I thought it was Arizona....

I thought it was in the car park of the local Tesco's with Elvis in the suit rather than Buzz Lightyear..

Seriously...anyone who thinks it's faked wants sectioning/shooting or both

[Milamber]

Oh wait, I am living in a conspiracy - I must be since I cannot see any stars...

It's daytime, so no stars - well, maybe one. Effectively, it was daytime on the Moon as well.

I always tell people that there is a star visible, the Sun. It seems to placate them.

Look, if they'd filmed it in Arizona (or Texas) the sky would have been full of contrails even if the Nasty Low Clouds had parted for once.

Only on a few occasions each year down here on earth though

Spot on.

I went to a presentation by Michael Fowles, the astronaut. Talking to him afterwards, he said that during "daytime" space walks, you can't see any stars either. They're simply lost due to the the glare from the earth (and sun).

But orbital night time is another story. He said the sky is ablaze with light and colour. The milky way is apparently astonishing - to the point of distraction. The same applies on the moon.

Be nice to see that, one day....

True - I heard it on Talksport last night when a caller rang in and saw it on the internet. So, it must be true then

[RichieP]

I always like to tell people it's like standing under a streetlight during a clear night. You can see the sky is black but you'll see no stars because it has to be dark to see stars!

Another way of thinking of it is its like being in a floodlight sports stadium at night. The sky is black but its practically daylight.

[Talitha]

I like the streetlight analogy, Richie!

Arizons it is!

But the fact's not half as true.

" why is not a single star visible in the astronauts moonwalk videos??? "

Because Chuck Norris ate them all .

[NickH]

He didn't eat them...Stars are just the dandruff on Chuck's hair (that is if Chuck had dandruff, which of course he doesn't)

Amanda you are right about the exposure time on the cameras.

Basically the exposure time was set to capture the moon walks, since the moon was so bright, with not only sunshine but also earthshine, the pictures would have been saturated had they had an exposure time long enough set to "see" stars. The lunar dust is actually highly reflective from what i gather, so alot of the radiation incident will be reflected back. This actually ties in to the arguements about the disappearing crosshairs in the apollo pictures.

Sometimes people forget that the moon is an alien world. You simply cannot compare experiences of what you are used to here on earth and apply them to the same situation on somewhere like the moon.

The reason we dont see the stars during the day here on earth, most people think because of the Rayliegh scattering making the sky blue, hence not being able to see stars. But you also wouldnt be able to see them in the absence of an atmosphere anyway.

And since paradoxically we will never observe stars during "daytime" in the absence of an atmosphere, it somehow seems inconceivable to some people.

Speaking of Chuck Norris, try googling for him and hit the 'feeling lucky' key...

You may already know this of course (while you're at it also try 'French Military Victories'.

[NickH]

Anyone who thinks it was faked...or believes a word of that Fox rubbish...I suggest

The Flat Earth Society -- Home

rather than here...much more your kind of thing..

:-)

[narrowbandpaul]

the flat earthers really make me laff.

there is at least the slightest glimmer of the possibility of a chance that the moon landing were faked.

but the flat earthers have no reason for their 'theories'

but for anyone who believes that.....if you give me £1million I can make you live forever.....

[NickH]

There is no glimmer of anything w.r.t the Moon landings, they went, they landed, they brought back a stack of rock, left several seismic test rigs, laser reflection devices, and other bits and bobs....

end of story...move on! :-)

As a Pro Am photographer of over 30 years standing, I can say with authority derived from personal experience, that Amanda's reasoning is spot on. Now look at this:-

Argument won I think!
