    This is for all of you astronomers:



    And yes, there are plenty of these videos, from different seasons, locations, years, etc.

    Put on that thinking cap!


    Let's play

    Are we sure that, that is the moon?

    And if it is, the clouds don't seem so opaque. That moon seems ridiculously bright. But if it is so bright, it's like holding a paper to a light bulb. The light bulb shines through. Of course, it appears that the moon is brighter than a light bulb and a piece of paper is more opaque than those clouds. That said, it's an optical illusion. The moon never gets as close as clouds.

    Again, there are plenty of videos out there... find some and post them as well.
    Nobody interested in playing?

    Discussion on colonizing the moon:



    "The whole moon program got cancelled, didn't you hear?"



    The Pizza/Moon analogy:




    Neil deGrasse Tyson says:

    Host: "If the moon is constantly getting farther away from the earth every year..."

    Tyson: "...About 2 inches a year"




    Discussion on terraforming the moon:

    "the moon is one of the most... the moon reflects like a sidewall tire"
    "the moon is a bad.., it's dark... it's as reflective as the surface of an iron skillet"

    So if the moon gets farther away from the earth by about 2 inches a year, and it is as reflective as an iron skillet....


    Neil deGrasse Tyson, explain this:




    How is the surface of the "moon" visible through thick and heavy cloud cover in this video, and a few others posted in this thread?

    Are these opaque cloud formations or is this moon in front of the cloud formations?


    Just more to chew on

    Just to add another for those that cannot see it that well


    Optical illusion?

    What alternatives do you think it could be?

    Look at what Tyson says about the moon moving farther away and being low reflective.
    Pretty much contradicts these images and videos.

    Either he is fabricating or like you asked "are we sure that, that is the moon?"

    So what would create such an optical illusion if this is the case, and if this is not really the moon?


    Respect

    Like Tyson said, the Sun is so bright (and close) that the moon's low reflectivity causes it to appear bright. I.e. if the moon reflect's 1% of the Sun's brightness, it's (roughly) 1/100th as bright as the Sun. 1/100 as bright as the Sun is still brighter than anything man-made.

    Case and point, the Sun's Luminosity is 3.8 x 10^26 W or 3.8 x 10^26 J/s.

    The nuclear bomb that exploded over Hiroshima had a yield of 63 Terajoules or 63 x 10^12 J.

    In other words, if the Moon reflects even 1% of the Sun's Luminosity, the Moon's effective Luminosity would be 3.8 x 10^24 J/s or reflect nearly a trillion times the energy as given by a nuclear bomb every second.

    Of course, we should bare in mind that the nuclear bomb's brightness can blind a person--like the Sun can blind a person. But there are other factors to light blinding a person than total 'brightness.' For example, a laser or flashlight can blind a person though their brightness can't be compared to a nuclear explosion or the Sun.
