===Trivia===
 Other permanently shadowed regions (spots) are parts of the inner steep walls and floors of several ''skylights'', although I don't think there are northern and southern ''skylights'', only the few near the equator (once in a lunar day they are illuminated by the sun at or near their zenith). We could only guess if there are subsurface tunnels near these ''skylights'', if so, they might receive their first light when unmanned crawlers explore their interiors. See [http://the-moon.us/wiki/Skylights Skylights].<br /> <span class="membersnap">- DannyCaes <small>Nov 9, 2017</small></span><br /> <br />

<br /> '''Appendix'''<br /> [https://my-moon.org/ The perfect globe-shaped MOON-balloon from sculptor Luke Jerram] (diameter''':''' 7 meter) also shows the permanently shadowed regions on the moon's north and south poles. Because this balloon is almost always hanging northpole-up/ southpole-down above the art-lovers and occasional visitors, the moon's southpole region is the most frequenly photographed part of it. I wonder if this 7 meter globe is also hanging in large indoor multiple-floor places where you could explore the northpole region too, from locations "above" the balloon.<br />  This MOON-balloon is composed of orbital LROC photographs (Lunar Reconnaissance Orbiter Camera), which means you see the most perfect globe-shaped lunar atlas ever created! (imagine such a MOON-balloon with additional IAU-nomenclature of the basins, craters, and mountain ranges'''...''' could be a superb hovering moon-atlas to be explored by those who have small binoculars'''...''') (a subtle red laser pointer could be very interesting to aim the attention of the visitors toward certain noticeable spots on the globe).<br />  I wonder how many (of the art-lovers and occasional visitors) are really aware of what they are looking at?<br /> <span class="membersnap">- DannyCaes <small>Nov 11, 2017</small></span><br /> <br />
