Just a little oddity. Has probably been noticed before. :)

Both taken from the same position in edras e10.

An explanation for that would be interesting.

My money is on the glowey thingy.
Anyway, it works the same way in real life. Back when I was somewhat interested in astronomy, I learned that several dimmer stars, the ones near a brighter star, are only visible out of the corner of your eye. This is probably because the brightness of the brighter star washes out the dimmer star if you stare straight at the pair, but turning your eye slightly changes the angle at which the light of the brighter star his your eye, in essence making it dimmer than the dimmer star, which happens to have a more favorable angle. Or something. Wee sugar!

certainly explains why I can't see the Pleiades if I look at them directly...

Heh.

The planet is being obscured because the sun is... weird. It's a sprite that rotates to always face you as you rotate your view, which is compounded by the fact that its position is stretched near the corners of the view because of the way perspective works on modern hardware. The end result is that its perimiter seems to move relative to things behind it, so the planet pokes its head out and then hides again as you turn.

As far as real life phenomena go... your eyes are simply more receptive to light in your peripheral vision. It's an evolutionary advantage - if you're a cave man wandering around in the jungle at night, you need to be able to see the light reflecting from a saber tooth tiger's eyes before the tiger pounces.

Cool, not a big deal anyway. Let's blame it on more receptive corners of the eye. <.<
Wow! You guys think of everything! :P

No seriously, I always thought planets and suns are rendered directly into the background texture (at lower quality settings atleast).
