Yebes Observatory RT40m

The Yebes Observatory houses a 40-meter radio telescope with a Cassegrain mirror system that directs radio waves using primary and secondary reflectors toward specialized receivers. The facility sits at 931 meters elevation and is equipped with modern instruments designed to capture faint signals from space.

The radio telescope was built between 1999 and 2007 as part of Spain's effort to advance radio astronomy research. This period marked an important phase in modernizing research infrastructure for space science across the country.

The National Geographic Institute of Spain operates this facility, contributing to international research networks and fostering collaboration among astronomers from different countries.

The observatory can be viewed from outside and visitors see the impressive antenna structure from various angles. A short walk around the facility provides a good overview of the telescope's size and construction.

The telescope can receive radio waves across a broad range from 2 to 90 gigahertz, setting it apart from many other facilities. This capability allows it to study different types of signals from space simultaneously.
