The Cosmic Microwave Background, or CMB, is a nearly-isotropic 2.725 K signal which formed during the epoch of recombination (when the universe went from being mostly ionized to mostly neutral) approximately 300,000 years after the big bang.
It was first postulated in 1948 by George Gamow, Ralph Alpher and Robert Herman, who predicted its temperature to be approximately 5k. However their work was largely forgotten until Robert Dicke arrived independently at the same prediction in the 1960s. The first publication discussing CMB radiation was in 1964 by two Soviet physicists.

Which observational tool helped astronomers Arno Penzias and Robert Wilson discover the existence of the cosmic microwave background (CMB)?
radio telescope
What is cosmic microwave back group radiation?
Cosmic Microwave Background (CMB) radiation is the afterglow of the Big Bang, providing a snapshot of the universe approximately 380,000 years after its formation. It is a uniform, faint glow of microwave radiation that fills the universe, with a temperature of about 2.7 Kelvin. The CMB is crucial for understanding the early universe's conditions, revealing information about its composition, structure, and expansion. Its discovery in 1965 provided strong evidence for the Big Bang theory and has since been instrumental in cosmology.
All of space is bathed in microwave energy. where did this energy originatens?
The microwave energy that fills all of space primarily originates from the Big Bang, which occurred approximately 13.8 billion years ago. This energy is a remnant of the hot, dense state of the early universe and is now observed as the Cosmic Microwave Background (CMB) radiation. As the universe expanded and cooled, this radiation stretched and cooled to the microwave wavelengths we detect today. The CMB serves as a crucial piece of evidence for the Big Bang theory and provides insights into the early conditions of the universe.
What is the scientific method used to determine the age of the universe?
The age of the universe is primarily determined through a combination of observational evidence and theoretical models, particularly using the cosmic microwave background (CMB) radiation and the expansion rate of the universe. The CMB provides a snapshot of the early universe, while measurements of the Hubble constant, which describes the rate of expansion, help estimate the time elapsed since the Big Bang. By analyzing these data alongside models of cosmic evolution, scientists estimate the universe to be approximately 13.8 billion years old.

What is cmb?
CMB stands for Cosmic Microwave Background, which refers to the faint radiation left over from the Big Bang. It is the oldest light in the universe and provides important clues about the universe's origin and evolution. Scientists study the CMB to learn more about the composition, age, and structure of the universe.
