Without further ado, here are the 3 things that made Carl Sagan famous.

Creating The TV Show Cosmos: A Personal Voyage

One of the reasons that Carl Sagan is so incredibly famous is because he created the most watched public television show ever.

In 1980 Carl Sagan appeared as the world’s first television science personality in his flagship series Cosmos. This 13 episode series sought to explain in layman terms how the universe worked.

Cosmos would air on the Public Broadcasting Service. To this day reruns are played and as a result over 500 million people worldwide in 60 different countries have been exposed to Carl Sagan.

The reason that Carl Sagan became so famous worldwide was due to his ability to explain extremely advanced concepts in a simple way.

In the first episode Carl Sagan explains to the audience the total timeline of the universe along with its expanse. Unlike previous scientists who use advanced terminology, Carl Sagan explains the entire universe using a dandelion seed he calls the “Ship of the Imagination.”

The entire Cosmos series continues to have Carl Sagan explain advanced concepts in very simple terms. This was the running theme of the show and overtime came to be Carl Sagan’s television personality.

Since the first publication of Cosmos Carl Sagan has achieved a legendary status among scientists and astronomers. As a result this is one of the primary reasons he is so famous today.

This is one of the main reasons that today Carl Sagan is so famous. He created one of the most recognizable shows in the history of mankind.

Pioneering The Field of Exobiology

One of the main reasons that Carl Sagan became so famous was his fascination with an emerging theoretical field of Exobiology.

Exobiology is the theoretical field of life found outside our own planet. While not discovered yet Exobiologists such as Carl Sagan would experiment with different climates to discover where life might exist in our universe.

For Carl Sagan this was his life long mission. Not only did he teach astronomy but he also conducted several experiments and wrote over 600 papers surrounding the possible discovery of alien life.

One of his most famous quotes comes from his Cosmos book where he discusses the possibility of alien life. Sagan often presented the mathematical formula that there are “billions and billions” of stars each with the possibility of harboring life.

Carl Sagan’s best known experiment was the discovery that the building blocks of life, amino acids, could be created by using radiation upon basic chemical compounds.

This experiment demonstrated to the world that life on other planets was possible. From this point on countries around the world would spend billions of dollars on research and space missions to discover life.

Since the 1980’s we have discovered habitable environments where life could survive but so far we have not discovered life. NASA over the past 40 years has spent billions of dollars and discovered water on mars, primordial carbon on Titan, and the possibility of life on Europe.

This all started with Carl Sagan spending his life’s work on to jump start the field of exobiology. This is one the main reasons why Carl Sagan is so famous today, he started the modern search for alien life.

Introducing the World to Astronomy

One of the major reasons that Carl Sagan is so famous is because he made the world fall in love with stars and the universe.

Carl Sagan had the rare ability to explain complex and abstract topics in an easy to understand manner. This allowed him to bring the previously complex field of astronomy to the world through his shows and books.

What happened over the past 40 years is that around the world people have begun to stare up at the sky. The last time this happened was during the cold war between the U.S and Soviet Union.

This time however it’s out of amazement and not fear. Carl Sagan launched a second space race for knowledge. Today the world has fallen in love with the stars all over again.

One of the main reasons for Carl Sagan’s fame is his view on the future of the human race. Carl Sagan feared above all the destruction of the human race from an asteroid or comet.

This fear became realized in 1992 when the Shoemaker comet crashed into Jupiter. An event that shocked the world and the explosion could be seen from earth.

Carl Sagan wrote his now famous book Pale Blue Dot to demonstrate how it should be the goal of all humans on earth to begin the process of colonization and terraforming space.

It was Carl Sagan’s never ending desire to show humanity the wonders of the universe that made him so famous. Today we remember him for his never ending pursuit of teaching and sharing the stars with over 500 million people worldwide.
