Holmdel Horn Antenna, Radio telescope in Holmdel Township, United States
The Holmdel Horn Antenna contains a 50-foot-long aluminum structure with a 20-by-20-foot radiating aperture mounted on a 30-foot diameter elevation wheel.
In 1965, physicists Arno Penzias and Robert Wilson utilized this antenna to detect cosmic microwave background radiation, leading to their 1978 Nobel Prize in Physics.
The antenna stands as a monument to scientific exploration, drawing researchers and students who study its contributions to radio astronomy and cosmology.
Visitors can access the antenna site in New Jersey following the 2023 purchase by Holmdel Township, which plans to transform the area into a public park.
The antenna's design includes a steel triangular base frame that rotates on a turntable track, enabling precise adjustments for astronomical observations.
