The Holmdel Horn Antenna is a large microwave horn antenna that was used as a satellite communication antenna and radio telescope during the 1960s at Bell Telephone Laboratories in Holmdel Township, New Jersey, United States. It was designated a National Historic Landmark in 1989 because of its association with the research work of two radio astronomers, Arno Penzias and Robert Wilson. In 1965 while using this antenna, Penzias and Wilson discovered the cosmic microwave background radiation (CMBR) that permeates the universe. This was one of the most important discoveries in physical cosmology since Edwin Hubble demonstrated in the 1920s that the universe was expanding. It provided the evidence that confirmed George Gamow's and Georges Lemaître's "Big Bang" theory of the creation of the universe. This helped change the science of cosmology, the study of the history of the universe, from a field for unlimited theoretical speculation into a discipline of direct observation. In 1978 Penzias and Wilson received the Nobel Prize for Physics for their discovery.

Holmdel Township is a township in Monmouth County, in the U.S. state of New Jersey. Located near the Raritan Bay within the Raritan Valley region, the township is a bedroom community of New York City in the New York Metropolitan Area.As of the 2020 United States census, the township's population was 17,400, an increase of 627 (+3.7%) from the 2010 census count of 16,773, which in turn reflected an increase of 992 (+6.3%) from the 15,781 counted in the 2000 census.Holmdel Township was formed by an act of the New Jersey Legislature on February 23, 1857, from portions of Raritan Township (now Hazlet). The origin of the township's name is unclear, with some sources indicating that it was named for the Holmes family, who were early settlers of the area, while others point to Dutch language words holm and del, meaning 'pleasant valley'.Holmdel is located 15 miles (24 km) west of the Jersey Shore. The township is notable, among other things, for its historical and present connection to Bell Labs. Important evidence for the Big Bang was discovered using the Holmdel Horn Antenna at a Bell Labs facility by Arno Penzias and Robert Wilson, both of whom won the Nobel Prize in Physics for their work here. In addition, former Secretary of Energy Steven Chu earned a Nobel Prize in Physics for his work on laser cooling in Holmdel.Holmdel's picturesque beauty, proximity to New York and main highways, award-winning public schools, large homes, rich history, the PNC Bank Arts Center, and the presence of many high paying jobs within commuting distance led the township to be ranked the #1 "Six-Figure Town" by Money magazine and CNN for 2009.The township has been one of the state's highest-income communities. Based on data from the American Community Survey (ACS) for 2013–2017, Holmdel Township residents had a median household income of $155,842, ranked 10th in the state among municipalities with more than 10,000 residents, more than double the statewide median of $76,475. Based on data from the 2006–2010 ACS, Holmdel had a per-capita income of $62,120, ranked 46th in the state.
