Io Plasma Torus
A bagel-shaped region of trapped sulfur ions around Jupiter that
originates from the surface of Io, one of Jupiter’s moons.
Gravitational tidal forces between Jupiter, other Galilean moons,
and Io cause tidal friction in Io’s interior, producing
geysers that spew sulfur at tremendous speeds. Some of the sulfur
ions leave Io’s surface and become trapped around
Jupiter.

to Apollo 14.
"The Hubble Space Telescope Repair Mission was
extraordinary on so many levels... The foresight to attempt
repairs rather than scrap the investment in the original telescope,

stunning visual images of the spacewalks transmitted from space,
and an outcome that extended the life of this marvelous portal into
the universe - all add up to an unmatched technological
achievement."
