www1.eere.energy.govNASA launches the first Orbiting Astronomical Observatory, powered by a 1-kilowatt photovoltaic array, to provide astronomical data in the ultraviolet and X-ray wavelengths filtered out by the earth’s atmosphere. 1969 The Odeillo solar furnace, located in Odeillo, France was constructed. This featured an 8-story parabolic mirror. 1970s

astronomy.nmsu.edumotion, and a staggering new body of astronomical observations. The observations were made possible by the invention of the telescope in Holland c.1608 and by Galileo's ability to improve on this instrument without ever having seen the original. Thus equipped, he turned his telescope skyward, and saw some spectacular sights.

www.grc.nasa.govgalaxy is obtainable from astronomical measurements, but is not necessarily treated in terms of a higher dimensional geometry3. It is treated, rather, as an abstract numerical measure related to the distance – a type of metric – between P and P*. S and θ, in turn, are related by another “constant of proportionality,” ρ.

However, these equations are not well-
