Observing the moon


Dear all, today I wish to clarify a puzzling matter that has had many skywatchers (including myself) scratching their heads; namely, the question of our Moon’s seemingly bizarre ‘behaviour’ and apparently fluctuating tilts / orientations as viewed from Earth. To be sure, spatial perspective is a quite challenging subject matter – especially when it comes to astronomical observations, what with all its angular variables (diverse earthly locations / observational frames of reference, oscillating seasonal tilts, latitudes & longitudes of our moons and planets, etc). This present exercise will also provide another opportunity to demonstrate the usefulness of the Tychosium 3D simulator and what I like to call its “explanatory power”.

Simon sees a curve

Took a few years, but Simon finally weighs in.

Lately, I’ve been discussing with a pen pal the issue of Earth’s curvature which, of course, is one of the Flat Earther’s favorite topics which they endlessly submit as ‘proof’ of the world’s flatness. Let me first make it clear that I do actually share ONE thing with the (earnest) Flat Earthers: that is, their quite reasonable request that whatever is claimed by astronomers should be EMPIRICALLY OBSERVABLE (that is, only under optical conditions that allow them to be observed).

all unreal | South is Center – North is infinite and unknown

Hard to keep one’s eye on the ball-earth and come to terms with how its geography can be levelled out and presented flat. Globe earth is so complex to render in 2D that we have hundreds of different maps and projections as experts like to label them.
