    One of the coolest photos I’ve ever seen. I like mountains amid the human development too

      I don’t understand why they call it an “accident”. The camera was set up and taking timed pictures. I just don’t think “accident” is accurate

      They’re not necessarily accidental (for example, taking long exposures during a meteor shower), but yes the vast majority of meteor pictures are by chance. A few meteors have been detected just before entry and photographed but that number is in the single digits.

      A lot of spaceship debris looks like this because copper is used in a lot of rocket engines.

      Alternatively or additionally, I think oxygen plasma glows blue or green, because northern lights (near the poles, at least) are greenish.

      Probably nickel and/or salts of barium. Copper burns blue as a pyrotechnic colorant.

        Depending on the salt you can make both blue and green. Copper sulphate flame test is a pretty common school lab practical isn’t it?

        Ah ok. I was going to say nickel but I did a quick search and somehow I read that it was copper.
