Nearly 40 years ago, the two Voyager spacecraft left Earth. Aboard each was a time capsule of humanity for extraterrestrials: a golden record containing sounds and images portraying the diversity of life and culture on Earth, including a diagram of DNA, greetings in 55 languages, a map of our solar system's position relative to stellar landmarks, the sound of a kiss, Louis Armstrong's "Melancholy Blues" and "Dark Was the Night -- Cold Was The Ground" by Blind Willie Johnson. Since culture and technology don’t stand still, Science Friday asks: "If humanity were to send another Golden Record to the stars, what would it contain?" An expert panel will review submissions from the public, and a new Golden Record will be unveiled on October 7. [more inside]
Sasha Sagan talks about Lessons of Immortality and Mortality From My Father, Carl Sagan.
The cosmos is also within us, we're made of star-stuff. We are a way for the cosmos, to know itself.
Cosmos: A Personal Voyage is a thirteen-part television series of one hour shows written by Carl Sagan, Ann Druyan, and Steven Soter, that was aired at the tail end of 1980 and was - at the time - the most widely watched series in the history of American public television. It is best introduced by an audio excerpt of one of his books, The Pale Blue Dot. Inside is a complete annotated collection of the series. [more inside]
The Mix Tape of the Gods: made to be played at 16-2/3 revolutions per second, now traveling 300 million miles per year
August and September 2011 mark 34 years in the journeys of Voyager 1 and 2. The two scientific probes, progeny of the Mariner program, were sent out to survey this solar system and beyond. Voyager 2 completed the Grand Tour in 2009 (excluding Pluto), and Voyager 1 is getting closer to interstellar space (previously). Both scientific probes were sent out in with a time capsule from 1977, golden records secured in plain view on the outside of the Voyager Spacecraft. These greetings from earth (alt links: Coral Cache, Archive.org) were recorded in the form of 116 images, a collection of sounds of this planet, greetings in 55 languages (YT), 27 songs from around the world, and brain waves of Ann Druyan, then recently engaged to Carl Sagan. For all that work, the "Mix Tape of the Gods" almost didn't get sent into space because of some last-minute writing in the run-outs. [more inside]
