"Rare Opportunity: Bid on Carl Sagan's Masterpiece, NASA's Voyager Golden Record"

A copy of the master recording for NASA's Voyager Golden Record, designed as the first recorded interstellar message from humankind, will be up for auction at Sotheby's New York. The recording, kept by Carl Sagan and Ann Druyan, is expected to fetch between $400,000 and $600,000. The Voyager probes, launched in 1977, continue to explore interstellar space and provide valuable data about the heliosphere. Despite their age, the probes are still operational and are expected to continue their missions for years to come.
