Fraunhofer is a lunar crater that is located just to the south-southwest of the walled plain Furnerius, in the southeastern part of the Moon. This crater appears foreshortened when viewed from the Earth, and is actually nearly circular.
This crater has undergone some erosion from lesser impacts, particularly along the northern part of the rim. The satellite crater Fraunhofer V lies along the northwestern edge and part of the inner wall. A pair of smaller craters also lie along the northern rim. The remainder of the rim is relatively intact, with small craterlets along parts of the inner wall. The interior floor is nearly level and is marked by a several small craterlets. The southern two thirds of the floor has a slightly lower albedo than the northern part.
Usage examples of "fraunhofer".
Like the Fraunhofer Institutes in Germany, MARC would bridge that gap with a formal structure for joint business-university research projects.
A similar politically wrong trend was recorded over fifteen years by the Fraunhofer Institute of Atmospheric Sciences in Bavaria, Germany.
Barry was back in the home continuum, rushing toward the blue-white inferno with enough velocity to shift the fraunhofer lines toward violet.
In the early Nineteenth Century Joseph von Fraunhofer developed a device, the spectroscope, which could identify the various components, or bands, in the light emissions of an energy source.
Von Fraunhofer himself directed his invention to the analysis of light from extraterrestrial sources.
Although he did not utilize the spectral analyses to study the chemical composition of space, von Fraunhofer may nevertheless be considered to be the founder of astronomical optical spectroscopy.
The instrument is a very powerful one, and, like the smaller one we looked through before, was made by Fraunhofer, a famous optician at Munich.
They looked exactly like what the astronomers called Fraunhofer lines, when the only way they had to know what a star or planet was made of was to study it through a spectroscope.
