“For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.”
“One glance at a book and you hear the voice of another person, perhaps someone dead for 1,000 years. To read is to voyage through time.”
“The universe is a pretty big place. If it’s just us, seems like an awful waste of space.”
“I don’t want to believe. I want to know.”
“If you wish to make an apple pie from scratch, you must first invent the universe.”

Life of Carl Sagan
Carl Sagan was an American astronomer, astrophysicist, author, and science communicator, renowned for his ability to make complex scientific concepts accessible to the general public. He is best known for his work in the field of extraterrestrial life and his contributions to the understanding of the cosmos.
Sagan was born on November 9, 1934, in Brooklyn, New York, to Samuel Sagan, a garment worker, and Rachel Molly Gruber, a homemaker. A voracious reader since childhood, his interest in astronomy was sparked when he discovered a book about stars in the local library. This interest turned into a life-long passion that led him to the University of Chicago, where he earned a bachelor’s degree in physics in 1955, followed by a master’s degree in 1956, and a Ph.D. in astrophysics and astronomy in 1960.
Carl Sagan’s career trajectory took him through some of the most esteemed institutions. His first academic post was at the University of California, Berkeley, where he contributed to NASA’s Mariner missions to Venus and Mars. Later, he moved to Cornell University, where he remained for the rest of his career, shaping minds and fostering a culture of curiosity and scientific inquiry.
Notably, Sagan’s work extended beyond academia. He was instrumental in the creation of the Pioneer plaques and the Voyager Golden Records—interstellar messages sent aboard unmanned spacecrafts, intending to convey the story of our world to extraterrestrials. This demonstrated his optimism and belief in the possibility of intelligent life beyond Earth.
Carl Sagan’s prolific career also saw him become a beloved science communicator. He authored over 600 scientific papers and was an author, co-author, or editor of more than 20 books. His most famous work, “Cosmos,” was published in 1980 and accompanied his television series of the same name. Both the book and the series conveyed the vastness and complexity of the universe in an engaging and approachable way. His other popular works include “The Dragons of Eden,” for which he won a Pulitzer Prize, and “Contact,” which was later made into a film.
As an advocate for scientific skepticism and the scientific method, Sagan contributed significantly to the popular understanding of science. He was a frequent and popular guest on talk shows, where he discussed topics ranging from nuclear disarmament to the environment, further cementing his role as a bridge between science and society.
Sagan passed away on December 20, 1996, from pneumonia, a complication of the bone marrow disease myelodysplasia. His passing was a significant loss to the scientific community and the broader public sphere, where he had been a guiding light and a passionate voice for scientific discovery.
