“[In] everyday life, it is very rare that we are confronted with new facts about events of long ago. Our memories are almost never challenged. They can, instead, be frozen in place, no matter how flawed they are, or become a work in continual artistic revision.”

American astronomer and science communicator of the mid-to-late 20th century, Carl Sagan made complex cosmic concepts accessible to the public through his books and television series. He championed scientific skepticism and the search for extraterrestrial life, blending rigor with poetic clarity to inspire wonder about humanity’s place in the universe.
