Radio telescope in Effelsberg
The radio telescope in Effelsberg with an aperture of 100 m is the second-largest radio telescope in the world. It was built between 1968-1971 and it was at that time the largest radio telescope in the world. It explores space by measuring radio waves (wavelengths between 90 cm and 3.5 mm).
Aside from its scientific importance, the telescope is a stunning piece of technology. Its delicate design and precise alignments make it a masterpiece in terms of architecture. In the last week I had the opportunity to visit it. The size of the mirror in combination with the – relative to the big mirror – thin connecting struts provide a breathtaking image. I would describe it as a Technology-Gothic, but I’m no architecture expert
Radio Observatory Stockart
More than one year later, I had the possibility to do a trip to the radio observatory Stockart. It is also located in the Eifel (in near of Bad Münstereifel) and was at the time of its construction (at the end of 1950's) the first free steerable radio telescope in Germany. At that time it was used both scientifically and militarily. Today it is a monument and it is still run by a team of enthusiastic amateur astronomers. It is a nice destination, e.g., for a bike ride. You can sign up to take a tour through the telescope (5,- € per person), what we did. The tour ends on the top platform, from where you can get an nice overview of the Eifel.
