Oh thats genuinely realy cool.

I remember back when I lived in Berlin and studied planetary Science there. One of the Professors calculated and predicted where one of those Meteors is gonna go down. So people went there and watched and photographed it. Afterwards there was a little bit of an all hands on deck where a lot of students with different Professors went out and searched for the remains of the meteorite.

  • Wait a second. They predicted (before it even entered atmosphere) where it was coming down with such a precision that you could not just go out and photograph it, but even go and collect remains? I thought this was barely possible if you have a radar that is actively tracking it through the last stages of the atmosphere, while for anything still in orbit you'd be lucky to guess the correct country.

    • The things in earth orbit have a very small angle of entry. I'd expect that if the angle is bigger, the deflection from the atmosphere would be smaller (if it survives the hit).

I wonder if the temporal noise reduction (evident in the video clips) is being applied before integrating the frames to create the thumbnails.
