The entry lists several rare astronomical events expected to occur after the year 10,000. Roughly 8,000 years from now.
Some highlights from the entry:
- The year 12,490: Pioneer 10 passes 3.8 light-years from Barnard's star.
- 25,000: The 1974 interstellar radio message sent by the Arecibo Observatory finally arrives at its destination, the M13 Great Globular Cluster.
- ~34,000: Pioneer 10 will pass 1.76 light-years from the the star Ross 248.
- 864,047: Pioneer 10 will approach the vicinities of eight other stars, including Altair, a star nine times the size of the Sun.
- 600,000,000 to 3,500,000,000 years from now(estimates vary): Slow but steady increase in solar luminosity will cause Earth's oceans to evaporate, leaving it inhospitable to life.
- 3,000,000,000: The Andromeda Galaxy and our Milky Way Galaxy are predicted to collide.
- 5,400,000,000: The Sun leaves the main sequence, becoming a red giant.
- 7,590,000,000: The red giant Sun engulfs the Earth.
- 100,000,000,000,000 to 1,000,000,000,000,000 (one quadrillion years): The Big Freeze according to many cosmologists. Intelligent life existing then may flee to other universes, as suggested by the physicist Michio Kaku. Beginning of the Degenerate Era of our universe. End of normal star formation and normal stars in the Milky Way/M31 super-galaxy. New stars formed only via brown dwarf collisions every hundred billion years or so.
- 100,000,000,000,000 to 10,000,000,000,000,000 (ten quadrillion years): The Universe ends in a Big Crunch according to Frank Tipler's Omega Point Theory, but its inhabitants experience an infinite subjective lifetime.
