One of the most important insights gained with data from the 25m radio telescope at Stockert Observatory is certainly the study of the structure of the Milky Way<\/a>. With our solar system<\/a> in the middle of our galaxy<\/a>, the Milky Way appears to us as a diffuse band of stars in the sky. Even early on, optical astronomers were able to take pictures of distant galaxies that had a distinct spiral structure, and with that, the question which shape our own galaxy has became pressing.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

In the early 1950s, measurements from the Dutch radio observatory Dwingeloo<\/a> indicated a spiral structure<\/a>, and this hypothesis was confirmed with data from Stockert.<\/p>\n

In addition, the Stockert radio telescope was used in preperation for the American lunar missions: By observing the thermal radiation<\/a> of the Moon<\/a>, important conclusions about the surface properties of the Moon and suspicions of an extremely thin atmosphere could be drawn.<\/p>\n

A brief, if imprecise, overview of the work can be obtained from Google Scholar<\/a> with a query such as “Stockert radio telescope OR observatory<\/a>“. Further information about the research can be found in the annual reports of the Astronomical Institute Bonn.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>
