I don't know if anyone said this but you can't hear sounds in outer space so... And if you can't but the headline mentions 'noise', it makes some go 'hmmm.....'

Try to learn something from everything that has been written. Education is a good thing.
"I don't understand it, so it can't be true." is not a good excuse. There are many things in this world we do not understand until we educate ourselves.
I hope that Santa brings you some desire to sit down and learn this year.
Merry Christmas!

Here a correctly exposed picture of the Moon one of mine notice the shutter speed and we have NO stars visible
1/400th of a second f8 iso 400, Sony SLT A37 with a 300mm lens (heavy crop)
Here are some pictures of STARS mine again notice the shutter speed 10 seconds.
All f3.5 10 secs iso 1600 one at 20mm the other 2 18mm focal length.
Pleiades & Taurus
Taurus the V shaped stars at top of picture and Orion below
Moon just about to rise the fat looking star above it is actually Jupiter and a couple of stars from Orion on the right Betelgeuse & Bellatrix.
Lets look at the other exposure details iso 400 for the Moon, iso 1600 for the STARS
Now the Aperture f8 for the Moon f3.5 for the STARS f3.5 that lets in more light than f8
If I had taken the Moon shot at f8 and iso 1600 the shutter speed would be reduced to 1/1600th of a second.
If I had shot the Moon at F3.5 and iso 400 the shutter speed would have been 1/2000th of a second
If I had shot the STARS at 1/400th of a second and f8 like the Moon the iso setting would be over 1.6 million iso
Here is a video of a Sony A7S one of the best low light cameras you can buy
f1.4 1/30th of a second but 256,000 iso
Now if that was shot at the same settings as my star images f3.5 iso 1600 the shutter speed would need to be 30 seconds.
The camera that filmed the Dragon X could NOT show the Dragon X correctly exposed and ALSO show stars it's that simple. If the camera used was digital then it's hot pixels .
In other words... "meaningless garbage."
FFS, shutter speed has nothing to do with showing stars. And there's no reason that a camera can't film the Dragon craft at the same time as stars.
And it's not "hot pixels" when the ISS' camera shows stars, regardless if it's digital.
Can you stop wasting my time now?

Well the good thing is that intelligent readers can discern who is trolling, and who is talking about real things.
At the end of the day, I believe that SpaceX’s video is obviously showing stars, as it seems obvious enough.

So no answer from you on how the pictures above don't show stars just proves you are the one that hasn't a clue last time it was contrast, now exposure settings.
Let's face it photography/video/digital imaging is NOT your subject
