In the infinite vastness of space and time, our planet is but a speck. Yet in that speck, life has arisen and from that life, we have come to know the Universe. We have looked deep into space and we have looked deep into time. We have seen the birth and death of stars, the dance of galaxies, and the fury of quasars. We have glimpsed the splendor of creation and we have felt the sublime grandeur of our place in it. This is Carl Sagan’s Cosmos, an exploration of who we are, where we came from, and where we are going. It is a journey through space and time, a pilgrimage to the stars. Join us now as we take our first steps on a journey that will take us to the ends of the Universe and beyond.

The Life and Career of Carl Sagan

Carl Sagan was an astronomer, astrophysicist, and science communicator. He is best known for his work as a science popularizer, which helped bring astronomy and other sciences to a mass audience. He was also the author of the bestselling book Cosmos, which was turned into a television series. In this article, we will take a look at the life and career of Carl Sagan.

Early Life

Sagan was born in Brooklyn, New York, on November 9, 1934. He was raised in the Lower East Side of Manhattan by his mother, a housewife, and his father, a garment worker. His father died when Sagan was only seven years old, and he was raised by his mother and maternal grandparents who were Jewish immigrants from Russia. As a child Sagan showed an exceptional interest in the night sky and would often lie on the roof of his building staring at the stars for hours. When he was four years old he began to learn Model T Ford engines with his grandfather who was a mechanic. Carl grew up poor but happy and loved to play with neighborhood children even though they were often several years older than him.

Sagan excelled in school and skipped several grades before enrolling at the age of sixteen at Cornell University where he studied physics and astronomy. He received his B.A. in 1955 and his M.A. in 1956 from Cornell. He also met his first wife, Doris Jean Freeman, while attending college. The couple married in 1957 and had three children together: Amy, Elizabeth, and Sasha


Sagan attended the University of Chicago, where he received both his undergraduate and his graduate degrees. He later became a professor at Cornell University.

During his time at the University of Chicago, Sagan became involved in the developing field of exobiology, which is the study of life on other planets. He also met a fellow student named Ann Druyan, with whom he would eventually have two children.

Professional Life

Born in Brooklyn, New York, in 1934, Carl Sagan was a gifted scientist and communicator who was among the first to bring the wonders of space into everyone’s living room. After finishing high school at age 16, Sagan attended the University of Chicago, where he earned his bachelor’s degree (1955) and his master’s (1956) and doctorate (1960) in astrophysics. He later taught at Harvard University (1963-1968), Cornell University (1968-1974, 1985-1996), and Stanford University (1971-1972).

Sagan’s scientific research focused on planetary atmospheres, atmospheric temperatures on Venus and Jupiter, rising sea levels on Earth due to global warming, nuclear winter created by a global nuclear war, the likelihood of finding intelligent life elsewhere in the universe, and SETI (the Search for Extraterrestrial Intelligence). He also wrote several books on astronomy and science for the layperson.

In addition to his work as a scientist and teacher, Sagan also played an important role in communicating science to the general public. He served as a scientific adviser for NASA missions including Mariner 9 (1972), Voyager 1 and 2 (1977), and Galileo (1989). He also wrote or co-wrote several popular books on astronomy, including Cosmos (1980), which was made into a successful television series in 1980. In 1995, he wrote The Demon-Haunted World: Science as a Candle in the Dark, a book about science and skepticism that continues to inspire readers today.

The Cosmos Television Series

Cosmos: A Personal Voyage is a thirteen-part television series written by Carl Sagan, Ann Druyan, and Steven Soter, with Sagan as presenter. The series was first broadcast by the Public Broadcasting Service in 1980, and has been rebroadcast a number of times since. It was also broadcast in the Soviet Union and several other Communist countries.


“Cosmos: A Personal Voyage” was Carl Sagan’s award-winning television series that aired on PBS in 1980. The series was first conceived by Sagan and Ann Druyan in 1977. After pitching the idea to various networks, they finally found a home at PBS, where the series was produced by scientific filmmaker Robert Zemeckis.

The show was an instant hit, becoming one of the most watched series in PBS history. It won several Emmy Awards and a Peabody Award. In addition, it sparked a renewed interest in science and astronomy among viewers of all ages.


Cosmos is a thirteen-episode television series written by Carl Sagan, Ann Druyan, and Steven Soter, with Sagan as presenter. It was broadcast by the Public Broadcasting Service in 1980, and has been rebroadcast a number of times most recently in April 2006. It remains the most widely watched PBS series in history. Each episode explores various scientific concepts in cosmology, astronomy, and space exploration. Topics covered included the origin of life on Earth, the development of civilizations, relativity, DNA, and extraterrestrial life.

The final episode of Cosmos ended with a look ahead to challenges faced by humanity in its quest for understanding of our place in the universe. Some of these challenges were self-imposed; poverty, disease, and war contribute nothing to furthering our knowledge. Other challenges come from nature; as our technology improves we are able to detect more potentially hazardous objects in space, such as asteroids. The final challenge discussed was one of perspective; as we gain knowledge about the universe it becomes clear how tiny and insignificant we are in comparison. The show ended with a call for humanity to unite in order to solve these challenges and become “a brain…the first thinking being in this vast and silent universe.”

The Legacy of Carl Sagan

In 1980, Carl Sagan released his documentary series Cosmos, which detailed the history and evolution of the universe. The series was a massive hit, and it inspired a new generation of scientists. Today, Carl Sagan’s legacy continues to inspire people all over the world. Let’s take a look at some of his most famous quotes.

Impact on Science

Carl Sagan was an American astronomer, cosmologist, and author who had a profound impact on the way we understand the universe. He is best known for his popular science book Cosmos, which was adapted into a Emmy Award-winning television series. Sagan was also a passionate advocate for space exploration and helped to popularize the idea of life on other planets. His work has inspired generations of scientists and continues to shape our understanding of the cosmos.

In the years after its initial publication, Cosmos became one of the best-selling science books ever published, and has remained in print since then. The book has been translated into dozens of languages and has inspired a television series, an award-winning stage show, and a number of subsequent books.

The book and television series had a significant impact on popular culture, helping to make science accessible and interesting to millions of people around the world. Sagan’s work also helped to rekindle public interest in space exploration at a time when many were losing faith in the possibility of discovering anything new about the universe.

Sagan’s vision for Cosmos was to create a “personal view” of the universe that would be accessible to everyone, regardless of their scientific knowledge. In this respect, he was successful: Cosmos has been read and enjoyed by people from all walks of life, including scientists, academics, students, and laypeople. The book continues to inspire new generations of scientists and explorers, and is likely to remain one of Sagan’s most important legacy.
