Tropic of Cancer
2013-02-19 16:11:13

The Tropic of Cancer, which is also referred to as the Northern tropic, is the circle of latitude on the Earth that serves as a marker for the most northerly position at which the sun may appear directly overhead at its zenith. This event happens once per year, at the time of the June solstice, when the Northern Hemisphere is tilted towards the Sun to its maximum degree. Its Southern Hemisphere counterpart, marking the most southerly position at which the Sun might appear directly...

Prime Meridian
2013-02-19 15:54:46

A prime meridian is a meridian, i.e. a line of longitude, at which the definition of longitude is zero degrees. A prime meridian and its opposite in a 360 degree-system, the 180th meridian, create a great circle. This great circle separates the sphere into two hemispheres. If one uses directions f East and West from a defined prime meridian, then they can be named Eastern and Western Hemisphere. A prime meridian is eventually arbitrary, unlike an equator, which is determined by the axis...

Equator
2013-02-19 15:46:08

An equator is the intersection of a sphere’s surface with the plane that is perpendicular to the sphere’s axis of rotation and midway between the poles. The Equator is normally referred to the Earth’s equator: an imaginary line on the Earth’s surface halfway between the North Pole and the South Pole, separating the Earth into the Northern Hemisphere and Southern Hemisphere. Other planets and astronomical bodies have equators that are similarly defined. The Equator is approximately...

Radio Astronomy -- Radio astronomy is the study of celestial phenomena through measurement of the characteristics of radio waves emitted by physical processes occurring in space. Radio waves are much longer than light waves. In order to receive good signals, radio astronomy requires large antennas. Radio astronomy is a relatively new field of astronomical research. The earliest investigations into extraterrestrial sources of radio waves were by Karl Guthe Jansky, an engineer with Bell...

The Moon -- natural satellite of a planet, in particular, the single natural satellite of the earth. The Earth-Moon System The moon is the earth's nearest neighbor in space. In addition to its proximity, the moon is also exceptional in that it is quite massive compared to the earth itself, the ratio of their masses being far larger than the similar ratios of other natural satellites to the planets they orbit (with the exception of Charon and Pluto). For this reason, the...
