The Cosmic Microwave Background (CMB) is a really important thing to study if we want to understand more about our universe. It is a kind of light that is left over from the Big Bang, which happened about 13.8 billion years ago.

There are a lot of people who have helped to study the CMB and make new discoveries about it. Some of the most important figures include George Smoot, John Mather, and Anna Sajina.

George Smoot is an American astrophysicist who won the Nobel Prize in Physics in 2006 for his work on the CMB. He helped to create a special machine called the Cosmic Background Explorer (COBE) that measured the temperature of the CMB and showed us that it is very uniform across the entire sky. This was really important because it helped to confirm theories about how the universe began.

John Mather is another American astrophysicist who won the Nobel Prize in Physics in 2006 for his work on the CMB. He also worked on the COBE project and helped to show that the CMB has a particular pattern that can tell us more about the properties of the universe.

Anna Sajina is a Russian-American astrophysicist who studies the CMB and other things in space using telescopes. She has helped to discover new galaxies and understand how they form and evolve over time. Her work has also helped us to learn more about the CMB and the history of the universe.

Overall, these scientists and many others have made important contributions to the field of CMB research. By studying this special kind of light, we can learn more about the beginning of the universe and how it has changed over billions of years.
