Could Vanishing Stars Be Alien Satellites Or Is This a Cold War Relic?

I live in Southern Ontario, Canada. I was born in 1950. When I was five, an announcement over the radio stated that we wern't able to drink milk as a nuclear test had been conducted with the fallout coming toward us. The cows would eat the grass with Strontium 90 contamination. So there was a two week period of no milk.

Hello, wonderful person! This is a two part series with the part 1 of the video here: https://www.youtube.com/watch?v=5_Pw_rY04sI This is the part where the Earth shadow disappearance is addressed too Also another study confirming that this was a result of photographic paper packaging: https://journals.aps.org/pr/abstract/10.1103/PhysRev.76.375

That is why dark plates are important for calibration. Basically test exposure of nothing. So just developed of unexposed plates. While patter of dots will be different it can give idea of statistics and development process issues. With electronic sensors it is even more important as some pixels will persistently by bad so dark frames are more useful. But still useful in analog astrophotography.

I used to live just north of the Palomar observatory. You could see the telescope dome from my back yard. You can go and see the telescope still. There is a lot of history there. Its a pretty cool place.

If the plates still physically exist, you could take samples of the gelatine on the surface and at different depths at suspected transient/contamination points and empty space (as a control) and use a GCMS or some other kind of mass spec and look for specific radionucleotides and their specific end products to physically prove the contamination hypothesis. And at this point, it is only a hypothesis, lacking any verifiable evidence.

I have an original Kodak hat as well, it was my late dads he worked with them/at the place a bit from what my moms told me :)

You’re a breath of fresh air in this cold world my friend. You make all Antony’s proud

More and more, I realize that the quality of the science of astronomy hinges on how accurate and precise the measurement tools are. This goes for every science domain, but in astronomy, especially so because we need to view enormous space objects from an unfathomable distance. Still amazed by the jwst, it's pretty mind-blowing that we even have images of some of the earliest galaxies and stars

Looking forward to hearing your take on this.

Hello wonderful Anton!!
