Planetary System
On May 4, 2000, the Geneva Extrasolar Planet Search Team announced the discovery of a 3 MJ planet in a 226 day orbit. Three years later on June 30, 2003, the same two teams using the same method discovered a 3.5 MJ second planet orbiting about halfway between the distances of Mars and Jupiter (or in the middle of the asteroid belt) in the solar system from the star.

“What is a television apparatus to man, who has only to shut his eyes to see the most inaccessible regions of the seen and the never seen, who has only to imagine in order to pierce through walls and cause all the planetary Baghdads of his dreams to rise from the dust.”
—Salvador Dali (1904–1989)
“Each generation’s job is to question what parents accept on faith, to explore possibilities, and adapt the last generation’s system of values for a new age.”
