3 giorni fa · The accidental discovery of the CMB in 1965 by American radio astronomers Arno Penzias and Robert Wilson was the culmination of work initiated in the 1940s. CMB is landmark evidence of the Big Bang theory for the origin of the universe.
28 mag 2024 · The American astrophysicist Arno Penzias, who has died aged 90, was responsible for one of the biggest cosmological revelations of the 20th century – the discovery of cosmic microwave background, the leftover radiation from the big bang.
17 mag 2024 · Sechs Jahrzehnte lang haben sich seit dem Zufallsfund von Arno Penzias und Robert Wilson unzählige Kosmologen, Astrophysiker und Radioingenieure der weiteren Erforschung der Drei-Kelvin-Hintergrundstrahlung gewidmet und sie mithilfe ausgeklügelter, kostspieliger Weltraummissionen hochgenau analysiert.
12 mag 2024 · This story begins in the mid-1960s, in Bell Telephone Laboratories–funded by none other than AT&T. Physicists Arno Penzias and Robert Wilson were creating a radio receiver, and discovered the CMB completely by accident. In fact, at first they were quite puzzled by a signal they were receiving.
20 mag 2024 · Failure is often fundamental to discovery. In the early 1960s, Robert Wilson and Arno Penzias, two scientists who were doing research in radio astronomy, were baffled by “noise” in their measurements of cosmic radiation. They couldn’t figure out why they couldn’t eliminate it from their data.
3 giorni fa · In experiments conducted in connection with the first Telstar communication satellite, two scientists, Arno Penzias and Robert Wilson, of the Bell Telephone Laboratories, Holmdel, New Jersey, measured excess radio noise that seemed to come from the sky in a completely isotropic fashion (that is, the radio noise was the same in every ...
2 giu 2024 · Arno Penzias and Robert Wilson were building a radio receiver for the Bell Telephone Laboratories in Murray Hill, New Jersey for experiments in satellite communication. They encountered radiation that was an annoying source of too much noise.
