		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 one of the few sciences where amateurs still play an active role, especially in the discovery 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.

	Stellar evolution - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-21)
		In astronomy, stellar evolution is the sequence of changes that a star undergoes during its lifetime, the millions or billions of years during which it emits light and heat.
		Stellar evolution is not studied by observing the life cycle of a single star—most stellar changes occur too slowly to be detected even over many centuries.
		Current understanding of stellar collapse is not good enough to tell whether it is possible to collapse directly to a fl hole without a supernova, if there are supernovae which then form fl holes, or what the exact relationship is between the initial mass of the star and the final object that remains.

		Cosmology, a discipline that has a large intersection with astronomy, made huge advances during the 20th century, with the model of the hot big bang heavily supported by the evidence provided by astronomy and physics, such as the cosmic microwave background radiation, Hubble's Law and cosmological abundances of elements.

	astronomy
		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.
		Optical astronomy describes the techniques used to detect and analyze light in and slightly around the wavelengths that can be detected with the eyes (about 400 - 800 nm).

	STELLAR EVOLUTION (Site not responding. Last check: 2007-10-21)
		Based on observations of stars at various stages of their evolution, astronomers have developed a general theory of stellar evolution, by which the Sun is a typical "main sequance" star, in the middle of its evolutionary lifespan.
		One does not study stellar evolution by observing the life cycle of a single star; but rather, by observing numerous stars, each at a different point in its life cycle.
		However, our understanding of stellar collapse is not good enough to tell us whether it is possible to collapse directly to a fl hole without a supernova, if there are supernovae which then form fl holes, or what the exact relationship is between the initial mass of the star and the final object that remains.
