This one didn't work for me either.  None of the real mysteries were ever discussed.  How can you have aliens steal something and then never explain it? 

Ditto on most all of the other bellyaching above.

I just reviewed this, never have time to look back on posts.  I did not realize there were three moon stealing stories.  There was the one where aliens are taking the moon, and one where the billionaire is having it painted dark.  I don't recall the third.

The third was about pushing for a change in the scientific classification of the moon to call it a planet.

I think all three are broadly about "losing the moon" in some sense or another, rather than "stealing the moon".  Physical loss, visible loss, pedantic loss.

As a lunar geologist, I really should have liked this story (or three) about the Moon. But I didn't, for all of the reasons people gave. :(

I did want to clarify one thing from the forum posts, though:

....not to mention, regolith (the material of the moon) is already extremely dark. Covering in ash is likely to *lighten* it. The reason we perceive the moon as at all bright is

a) The sun shines on it and the sun is REALLY BRIGHT
b) We see it when the sun is down, and NOT lighting up our atmosphere, and we see it against a black background with superfaint stars....

Only the mare regolith is very dark, because the maria are made of basalt, a very dark rock. Regolith from the highlands is quite bright, because the highlands are made up of anorthosite, a very bright rock. So, a carbon-based ash would, in fact, darken the highlands. Though, it wouldn't be enough to make the Moon disappear, because even the very dark maria reflect enough sunlight for us to see them.

Also, we do see the Moon when the Sun is "lighting up our atmosphere". It is not uncommon to see the moon during the day, especially in the early morning or late afternoon.

Yeah Buzzfeed is not necessarily the place to find deep riveting science conversations. As far as telescopes go though, I am content with my Celestron 127EQ PowerSeeker Telescope. Helps me look at the star at night and spot the occasional meteor. toponlinereviews.com
