The Public Observatory (“Volkssternwarte”) at Hangeweiher has been in operation since 1935 \u2013 a joy for Aachen’s hobby astronomers. <\/h4>\n

<\/p>\n

“When a supernova explodes, it can light up as bright as a whole galaxy,” says Karl Wyrsch, retired Mathematics, Physics and Astronomy teacher. And then he continues \u2013 about the formation of planets, the characteristics of stars, and the grand mystery of black holes. His audience in the conference room of Aachen’s Public Observatory listens intently to every word. But most of all, the people gathered there are looking forward to seeing the centrepiece of the observatory: the huge telescope in the dome.
\nA 20-centimetre lens, with a 3-metre focal length, precision crafted by the master lens makers of the company Carl Zeiss \u2013 while Wyrsch supplies facts and figures about the telescope, he performs the well-rehearsed routine of opening the cupola. The old wood creaks.<\/p>\n

Everything still in its original condition<\/strong>
\nThe observatory has been in operation since 1935. In those days, the location at Hangeweiher was on the extreme outskirts of the town, far away from any artificial lighting. As a so-called “Public Observatory” the small observatory’s mission has always been to impart basic astronomical knowledge to broad segments of the population. Germany boasts 27 of these public observatories. What makes Aachen’s observation post special is that \u2013 in spite of some damage incurred in the Second World War \u2013 the building has survived in its original condition, along with all the original equipment.<\/p>\n

Live images from Mars<\/strong>
\nOne after the other, the visitors climb the steps to look through the eyepiece. “I can hardly wait to look through the telescope,” says one little girl. Mars is on the discovery menu today. Its red colour is due to iron oxide dust. Its distance from the Earth varies immensely \u2013 between 56 and 401 million km. One thing is for sure: it’s very, very far away. So far, and yet so near. After ample amounts of oohs and aahs, it’s time to go home, especially for little girls. But everyone can look forward to the next celestial event: images from Mars, transmitted live by the NASA InSight Mars Lander on Monday, 26.11.2018.<\/p>\n
