You are absolutely right, it is a linier equation - I stand corrected - thanks.

The 0.5 degrees of arc (it's not 2 degrees) is simply there is 360 degrees of viewing angles and a Full Moon will cover 0.5 degrees of the 360.

Sorry, it is not a linier equation. The Moon covers on average 2 degrees of arc (or is ir 0.5?). If Mars was at the same distance as the Moon it would measure 4 degrees - that would be a linier measurement. For the distances of the rest of the planets to equal 2 degrees arc, the equation would have ...

The plasma filaments are going in both direction, they traverse along the magnetic lines away from the Sun's surface then return, only the hottest of the ions break free to become part of the solar winds. If the magnetic line "Snaps" or breaks, the result is a solar flare with the ions loo...

The actual definition of a "Blue Moon" is the second full moon in a given month, it happens once ever 18 months or so, it has nothing to do with the Moon's color ("colour" to our Canadian and European friends).

Most of the Sun's activity at the surface and in the aureole is forged by the strong magnetic fields. Nearly all movement travels along them.

Experiments using massive orbiting pulsars should reveal an answer in a few years as to the speed of gravity, so far, faster than C looks like the most probable outcome.

The atmosphere is also thinner at the higher elevations, it's simple particle separation as would be seen along a shore line, the smaller particles are dispersed farther than larger ones. These have moved much less keeping the edges more pristine.

If they moved, their edges would be much rounder.

There is no atmosphere on Dione, Cassini may get closer on a future pass, it requires too much fuel to make anything other than small corrections or changes in it's orbit.

The terns are sometime misused, or the term nova is used as a general word for all nova types.

Nova: exploding star producing a dwarf of various types
Super Nova: creates a neutron star

I'm saying it is possible that the speed of gravity could be faster than the speed of light. In the String Theory the gravity model has the graviton as an open ended loop, to over simplify, it means part of gravity exists outside of our 4 dimensional world allowing it "violate" the laws of...
