"Nobel Physicist Arno Penzias, Co-Discoverer of Big Bang Echo, Dies at 90"

Arno A. Penzias, Nobel laureate and physicist, has passed away at the age of 90. He was known for his groundbreaking work in helping find early evidence of the Big Bang Theory and was awarded the Nobel Prize in physics in 1978 for his contributions. His research with colleague Robert W. Wilson involved the discovery of cosmic microwave background radiation, which supported the current theory of the origin and development of the universe. Penzias' life was marked by his escape from Nazi Germany, his contributions to science, and his later work in Silicon Valley.
