1.3 Flashcards
Archaeoastronomy
when investigations link archaeology and astronomy
Describe copernicus theory of the orientation of the solar system
The retrograde motion of the planets could be readily explained if the sun, rather than the earth were at the center of the universe, the earth is a planet, and the planets move around the sun in circles
describe the mars retrograde
as the Earth approaches a part of the orbit closest to Mars the production of the Earth-Mars line outwards the stars move slightly against the stellar background as Earth comes to the point in his orbit closest to Mars then passes it the projection of the line joining the two planets go backward since the Earth is going quicker than Mars as Earth continues to orbit Mars goes forward again
the heliocentric model led copernicus to what 2 additional result
He was able to work out the distances to the planets based on observation of their motion across the sky with respect to the changing of the sun.
He was able to derive the periods of the planets
describe Stonehenge and how it is relevant to astronomy
It contains a set of giant Standing Stones when 25 each, it relates to astronomy because at the summer solstice when the sun is the farthest north in the day of the longest the sun rises over a certain Stone
describe Newgrange and how it is relevant to astronomy
Huge Mounds known as passage Graves. It has a Huge Central chamber 50 ft high with a long tunnel.
they are used for ceremonial astronomical purposes. The tunnels are oriented in astronomically significant directions
describe some of the astronomy that the Mayan people used
They base their calendar by the sun and moon and the rising and setting of venus they can tell from Venus the dates of its heliacal Rising many features of their buildings and measurements are aligned to astronomical phenomena
describe some of the astronomy that the native American people used
They use a medicine wheel it’s line are drawn between significant marking point to the sunrise and sunset but also toward the rising Point are the 3 brightest stars
