Timeline of Io
Return to home
Io is 2,000 miles in diameter and orbits 260,000 miles above Jupiter. Every 42 hours every point on Io goes from high tide to low tide and the rocky surface rises and falls up to 300 feet or more and lava erupts constantly.
(SFC, 5/19/00, p.A17)
1610 Jan 7, The astronomer Galileo Galilei sighted four of Jupiter's moons. Galileo discov-ered the 1st 3 Jupiter satellites, Io, Europa & Ganymede. He discovered mountains and valleys on the moon, that Jupiter has a moon of its own, and that the sun has spots which change. Galileo discovered multiple moons around Jupiter. He also observed Mars.
(V.D.-H.K.p.200)(SFC, 11/5/96, p.A4)(SFC, 11/29/96, p.A16)(AP, 1/7/98)(MC, 1/7/02)
1676 Ole Christensen Romer (Roemer), Danish astronomer, derived a speed of light of 130,000 miles per second based on his observations of Io, the innermost moon of Jupiter.

1997 Dec 16, Metallic cores inside Io, Ganymede and Europa and the lack of a similar core inside Callisto was also indicated.
(SFC,12/17/97, p.A4)
1998 Oct 13, New photos from the Galileo satellite showed glowing lava and an arc of light generated by power surges due to volcanism, magnetic field generation of power and the grav-ity of Jupiter.
(SFC, 10/14/98, p.A4)
1999 Nov 25, The Galileo spacecraft flew to within 186 miles of Io's surface. Radiation shut down its cameras and other equipment 4 hours before the point of closest approach. The Io volcano called Loki was shown to be the most powerful in the solar system.
(SFC, 11/27/99, p.A6,7)
2001 Aug 5, The spacecraft Galileo flew as close as 120 miles above Io’s north pole and cap-tured wisps of volcanic gas largely composed of sulfur dioxide.
