Carl Sagan was a pioneer in the search for extraterrestrial life and a strong advocate for astrobiology, the science that studies the possibility of life on other planets. His interest in extraterrestrial life was manifested through various aspects of his career, from scientific outreach to his involvement in research and space exploration projects.
Sagan collaborated on the design of the
interstellar messages aboard the Pioneer 10 and 11 and Voyager 1 and 2 probes,
intended to communicate with potential extraterrestrial civilizations. These
messages included sounds and images selected to portray the diversity of life
and culture on Earth.
Furthermore, Sagan was a co-founder of SETI
(Search for Extraterrestrial Intelligence), a scientific initiative dedicated
to searching for signals from extraterrestrial intelligences through the
observation and analysis of space signals. His book "Contact"
reflects this passion, exploring the idea of what would happen if humanity
received a signal from an extraterrestrial civilization.
Through his work and enthusiastic communication, Carl Sagan played a crucial role in fostering public and scientific interest in the search for life beyond our planet, always maintaining a rigorous scientific approach combined with deep curiosity and an open mind about the possibilities of the universe.
Carl Sangan I make great and important contributions. Knowing about him and his works transmits that interest and curiosity for what may be on other planets, abroad; about extraterrestrial life, it's really impressive.
