In honor of Clyde William Tombaugh [1], the astronomer who discovered Pluto, a canister [2] containing his ashes is on-board the New Horizons space probe. It reads: "Interned herein are remains of American Clyde W. Tombaugh, discoverer of Pluto and the Solar System's 'Third Zone.' Adelle and Muron's boy, Patricia's husband, Annette and Alden's father, astronomer, teacher, punster, and friend: Clyde W. Tombaugh (1906…
It's interesting that by sending his remains on that probe we basically guaranteed that at least some human remains will survive millions of years in interstellar space, unless of course, New Horizons collides with something(which I guess it will, given enough time?).
Although our own solar system is believed to support no other life than on Earth, other stars in the galaxy may have hundreds of thousands of habitable worlds. Races on these worlds may have been able to utilize the tremendous amounts of power required to bridge the space between the stars..." Tombaugh stated that he had observed celestial phenomena which he could not explain, but had seen none personally since 1951 or 1952. "These things, which do appear to be directed, are unlike any other phenomena I ever observed. Their apparent lack of obedience to the ordinary laws of celestial motion gives credence."
