Carl Sagan

Hello! My name is Carl Sagan, and I want to tell you about my journey exploring the stars. I was born on November 9th, 1934, in a big city called Brooklyn, New York. Even as a little boy, my head was full of questions about the universe. I would look up at the twinkling night sky and wonder, 'What are stars?' When I was about five years old, my parents took me to the 1939 New York World's Fair, which was full of amazing ideas about the future. A trip to the library finally gave me my answer: stars were other suns, just very, very far away. The universe was so much bigger than I had ever imagined, and from that moment on, I knew I wanted to spend my life studying it.

My love for the cosmos led me to college at the University of Chicago. I studied everything I could about space—physics, astronomy, and astrophysics. In 1960, I earned my Ph.D., which meant I was officially a doctor of the stars! I became a professor and taught other curious students at universities like Harvard and Cornell. As an astronomer, my job was to study planets, stars, and galaxies to understand the rules of the universe. I got to work with NASA, the American space agency, to help plan missions for amazing robot explorers that would travel where no human could go.

I was so excited to be part of NASA's projects. I helped with the Viking missions that landed on Mars in 1976 to search for any signs of life. I also thought, 'If we are exploring space, maybe we should leave a message for anyone who might find our spacecraft.' In 1972, I helped design a special drawing called the Pioneer Plaque, which was like a 'hello' note from Earth sent out on the Pioneer 10 spacecraft. Then, in 1977, I led a team to create the Voyager Golden Record. This was a collection of sounds and pictures from our planet placed on the Voyager 1 and 2 spacecraft. It had greetings in 55 languages, music from around the world, and photos of people and nature. It was like a mixtape for the universe, a story of who we are, sent on a journey across the stars.

I believed that science wasn't just for scientists in labs; it was for everyone. I wanted to share the awe and wonder I felt about the cosmos. In 1980, I hosted a television show called 'Cosmos: A Personal Voyage.' On the show, I invited everyone to join me in my 'Spaceship of the Imagination' to travel through space and time. We explored everything from the tiniest atoms to the largest galaxies. Later, in 1990, I asked NASA to turn the Voyager 1 spacecraft around and take one last picture of home. The photo showed Earth as just a tiny 'Pale Blue Dot' in the vast darkness of space. It reminded me that our planet is a special and fragile home that we all must share and protect.

I lived to be 62 years old, and my own journey ended on December 20th, 1996. I spent my life sharing the story of the universe because I wanted everyone to feel connected to it. People remember me for helping them understand our place in the cosmos. I hope I have inspired you to stay curious, to look up at the night sky with wonder, and to never stop asking big questions. The universe is waiting for you to explore it.
