Astronomy is one of the oldest sciences. Astronomers of early civilizations performed methodical observations of the night sky, and astronomical artifacts have been found from much earlier periods. However, the invention of the telescope was required before astronomy was able to develop into a modern science.
		Astronomers study the night sky including the galaxies, black holes, and the stars. Today there is Radio Astronomy, Infrared astronomy, Optical Astronomy, Ultraviolet astronomy, x-ray astronomy, and Gamma ray astronomy.
