is the sun more dangerous to humans outside of earth (on the moon, for example ;)) because of the lack of an ozone layer? what exactly would long-term sun exposer without an ozone do, if you know!
IT SURE IS. the moon reflects the sun to shine oh-so-bright for us, after all!
the solar rays that hit the moon are unfiltered and SUPER dangerous actually, and are one of the reasons Neil and his buddies needed basically a complete suit of armor with a face shield built in:
solar rays on the moon FAR surpass those on earth in both intensity and the spectrum of radiation they carry. these rays are capable of destroying solar panels by overloading them, and every piece of optical equipment (including cameras!) ever used up there had to be specially designed to be shielded from all that junk.
if you had a telescope good enough to give you a 4k view of the lunar surface, you could see the long-term effects of these ultrarays yourself- all those flags we left all over the moon in fits of hyper-nationalistic pride?
yeah, they're almost certainly just piles of sun-bleached white rags, if not actual dust at this point.
and don't get brilliant ideas about going up there to commit moon grand theft auto on the lunar rover, either- all the equipment that's been sitting in the sun for 50 years is probably no longer in working order, even if it is in one piece. (UTMOST TRAGEDY)
and now you know!
