Astronomy the moon will look 50 x as large as it did before.

Kirchoff's laws describe three types of spectra: a) a "hot solid, liquid or gas," that is under high pressure, is known to give off "continuous spectrum"; b) a hot gas that is under low pressure produces a "bright-line or emission line spectrum"; and c) a dark line or "absorption line spectrum" is visible when a "source of a continuous spectrum is viewed behind a cool gas under pressure" (Cornell.edu).

Reflector telescopes don't go through chromatic aberration because the wavelengths reflect off the mirror in the same exact way; reflector telescopes cost less and just one side of the reflector telescope's objective must be perfect.

FOUR: Special relativity is a theory that looks into how matter is able to move through space and time.

FIVE: Which region of the electromagnetic spectrum has: a) the longest wavelength (radio waves); b) the highest photon energy (at the top of the spectrum; where the shortest wavelengths are found); c) the peak wavelength emissions of the Sun (in the visible part of the spectrum)?

SIX: The Sun's...

is 81.5 Lys away; c) 32.6 Lys.
EIGHT: The law of hydrostatic equilibrium is the situation in fluid mechanics where a volume of any fluid is at a point of constant velocity.

NINE: Why are light years more effective at describing astronomical distances than miles? Frankly it is simpler and easier just to use, for example, 4.2 light years rather than 24 trillion, 690 billion, 226 million, 567 thousand 371.2 miles.

TEN: The eight phases of the moon are: new moon; waxing crescent; first quarter; waxing gibbous; full moon; waning gibbous; last quarter; waning crescent. The appearance of the moon depends on the amount of sunlight that is reflected from the moon's surface; as it takes its monthly trek around earth, the side of the moon reflecting sunlight is seen from various angles.

ELEVEN: Venus orbits the Sun…
