Time Travel Trail at the Effelsberg Radio Telescope

Highlight • Trail

The interesting “time travel path”, which was opened for the 50th anniversary of the Effelsberg radio telescope in 2021, begins and ends at the visitor pavilion of the radio telescope. It runs for a total length of just over 5 km around the site of the radio observatory. Unfortunately, Caterpillars have left ruts on the forest floor. If it has rained, the path is sometimes muddy.
The time travel path at the Effelsberg radio telescope includes a total of 20 stations and the first 50 years in the history of the Effelsberg radio telescope (1971-2021) are presented. Further information at mpifr-bonn.mpg.de/effelsberg/visitor/zeitreiseweg.

Effelsberg Radio Telescope

Highlight • Monument

From the path that leads over the meadows above Max-Planck-Strasse, you have a beautiful view of the Effelsberg radio telescope. In addition, there is usually less going on there than on the street.

Effelsberg Radio Telescope

Highlight • Monument

The Effelsberg radio telescope is one of the most powerful observatories in Europe. The large surface of the antenna with an opening of approximately 7,850 square meters and a diameter of 100 m is important for the secure reception of the extremely weak radio signals from long distances. The total weight of the steel structure is 3,200 tons. The telescope's parabolic mirror can be rotated 360 degrees in just under fifteen minutes and tilted almost 90 degrees in about five minutes. This allows the entire sky above the horizon to be observed with the telescope. More interesting information is available here: mpifr-bonn.mpg.de/effelsberg
