Specks in Time

In 1977 the unmanned probes Voyagers I and II were launched to explore Jupiter and Saturn.  The completed their missions.  And they are still alive and going, farther and farther from the Earth, and transmitting interstellar space data.  They are close to leaving our Milky Way.  Their data transmission batteries should last another 14 years roughly.  After that the Voyagers will keep moving away from the Earth.   Potentially they could travel for BILLIONS of years!  In about 5 Billion years our Sun will consume the Earth and life will end.   (We'll see.  Man can be very inventive.)   So the Voyagers could outlive us, and perhaps if there is intelligent life elsewhere and they find a Voyager there is information available on board about us and the Earth to be decoded.  The information includes music, images, and greetings in hundreds of dialects.  (Thanks to Peter Krauss for the above.  He writes:   "The universe will go on quite nicely with or without us." and "...perhaps giving the impression (from the information mentioned above) that we knew we were lucky to exist for a brief time on this cosmic speck, instead of suffering under the solipsistic notion that we somehow reigned supreme in a universe created for us."
