	Astronomy and astrophysics - Wikipedia
		Astronomy, which etymologically means laws of the stars, is the science whose subject is the observation and explanation of events outside the earth.
		Astronomy is one of the few sciences where amateurs still play an active role, especially in the discovering and monitoring of transient phenomena.
		Astronomy is not to be confused with astrology, a pseudoscience which attempts to predict a person's destiny by tracking the paths of astronomical objects.

		Astronomy, which etymologically means "law of the stars", is a science involving the observation and explanation of events occurring outside Earth and its atmosphere.
		Astronomy is one of the few sciences where amateurs still play an active role, especially in the discovery and monitoring of transient phenomena.
		In astronomy, the main way of obtaining information is through the detection and analysis of electromagnetic radiation, photons, but information is also carried by cosmic rays, neutrinos, and, in the near future, gravitational waves (see LIGO and LISA).

		ASTRONOMY, science dealing with all the celestial bodies in the universe, including the planets and their satellites, comets and meteors, the stars and interstellar matter, the star systems known as galaxies, and clusters of galaxies.
		Astronomy grew out of problems originating with the first civilizations, that is, the need to establish with precision the proper times for planting and harvesting crops and for religious celebrations and to find bearings and latitudes on long trading journeys or voyages.
		Greek astronomy was transmitted eastward to the Syrians, the Hindus, and the Arabs.

	astronomy
		Astronomy, which etymologically means "law of the stars", (from Greek: αστρονομία = άστρον + νόμος) is a science involving the observation and explanation of events occurring outside Earth and its atmosphere.
		Astronomy is not to be confused with astrology, a pseudoscience that attempts to predict a person's destiny by tracking the paths of astronomical objects.
		Observational astronomy is concerned mostly with getting data, which involves building and maintaining instruments and processing the resulting data; this branch is at times referred to as "astrometry" or simply as "astronomy." Theoretical astrophysics is concerned mainly with figuring out the observational implications of different models, and involves working with computer or analytic models.

	Solar system (Site not responding. Last check: 2007-11-03)
		In broad terms, the solar system consists of the Sun, eight bodies in relatively unique orbits (commonly called planets or major planets) and two belts of smaller objects (which can be called minor planets, planetoids, meteoroids, planetesimals or, in the case of Pluto, planets).
		In the outer regions of this solar nebula, ice and volatile gases were able to survive, and as a results, the inner planets formed minerals and are rocky, and the outer planets were massive enough to attract gases.
		The point at which the solar system ends and interstellar space begins is not precisely defined, since its outer boundaries are delineated by two separate forces: the solar wind and the Sun's gravity.

		Although the term "solar system" is frequently applied to other star systems and the planetary systems which may comprise them, it should strictly refer to our system specifically: the word "solar" is derived from the Sun's Latin name, Sol (and the term sometimes appears as Solar System).
		In broad terms, the charted regions of our solar system consist of the Sun and its planetary system: the eight bodies in relatively unique orbits (commonly called planets or major planets) and two belts of smaller objects (which can be called minor planets, planetoids, meteoroids, planetesimals or, in the case of Pluto, planets).
		In the outer regions of this solar nebula, ice and volatile gases were able to survive, and as a result, the inner planets are rocky and the outer planets were massive enough to capture large amounts of lighter gases, such as hydrogen and helium.

		He detects infrared light by measuring the temperatures in the colors of the solar spectrum created by passing sunlight through a prism.
		It will combine the light from the twin Keck telescopes to measure the emission from dust orbiting nearby stars, directly detect the hottest gas giant planets, image disks around young stars and other objects of astrophysical interest, and survey hundreds of stars for the presence of planets the size of Uranus or larger.
		The primary goal of Darwin is to search for Earth-like planets around nearby stars, and to search for signs of life on these planets by studying infrared spectral lines in their atmospheres.

		This releases energy which escapes from the surface of the Sun in the form of electromagnetic radiation and neutrinos (and to a smaller extent as the kinetic and thermal energy of solar wind plasma and as the energy in the Sun's magnetic field).
		For some time it was thought that the number of neutrinos produced by the nuclear reaction in the Sun was only one third of the number predicted by theory, a result that was termed the solar neutrino problem.
		To obtain an uninterrupted view of the Sun, the European Space Agency and NASA cooperatively launched the Solar and Heliospheric Observatory (SOHO) on December 2, 1995.
