Astronomy the Moon Will Look 50 X

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 photosphere is what appears to be the surface (or the atmosphere), although there is no distinct surface; the Sun's chromosphere is the collection of gases that extend well beyond the photosphere.

SEVEN: Calculate the distance of the following stars: a) Star A is 16.2 Lys away; b) Star B. 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 (inside Earth's orbit) so because it never goes outside the earth's orbit it can never be more than 47 degrees above the horizon at sunset (law of physics). Venus is an inferior planet because its orbit is between earth's orbit and the sun.

TWELEVE: The Seasons on earth are caused by the tilt of the earth on its axis and by the fact that as the earth orbits the sun different hemispheres receive less direct rays from the sun; for example, when it is summer in Australia it is winter in North America, and vice -- versa.

THIRTEEN: Kepler's 3 laws of planetary motion: a) planets move around the Sun in ellipses and the Sun is at one focus; b) the line connecting the Sun to a planet sweeps equal areas in equal times; and c) the square of the orbital period of a planet is "proportional to the cube (3rd power) of the mean distance from the Sun" (Stern, 2007).
