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.

An expert panel will review submissions from the public, and a new Golden Record will be unveiled on October 7. [more inside]

Want to make eggnog weeks ahead of time? You might try this recipe, courtesy of The Rockefeller University's Dr. Rebecca Lancefield (PDF biographic article). In this 2008 video, her colleagues demonstrate how to make it; they suggest starting it now, tasting it at Thanksgiving, and drinking it at Christmas. In their 2009 follow-up video, they intentionally add Salmonella to the recipe as they make it, to see if the added liquor kills off the infection. Videos courtesy of Science Friday.
