This image of Jupiter was taken January 9, 1979 by TV cameras aboard Voyager
1. The image was taken while Voyager was still 54 million km (34 million
miles) from its closest approach to Jupiter.

This image shows Jupiter and two of its Galilean satellites (Io, left,
and Europa). The image was taken by the Voyager 1 spacecraft February
13, 1979 at a distance of about 20 million kilometers (12.4 million miles)
from the planet. In this image, Io is about 350,000 kilometers (220,000
miles) above Jupiter's Great Red Spot and Europa is about 600,000 kilometers
(375,000 miles) above Jupiter's clouds.

This mosaic of Jupiter was assembled from nine separate images taken through
a violet filter by Voyager 1 on February 26, 1979. The spacecraft was
7.8 million kilometers (4.7 million miles) from Jupiter.

Jupiter and its four planet-size moons, known as the Galilean Satellites,
were photographed in early March, 1979, by Voyager 1 and assembled into
this collage. They are not to scale but appear in their relative positions.
Startling new discoveries on the Galilean Moons and the planet Jupiter
were made by Voyager 1 and prompted new mission parameters for Voyager
2's flyby of Jupiter in July. Reddish Io (upper left) is nearest Jupiter;
then Europa (center); Ganymede and Callisto (lower right). Nine other
much smaller satellites circle Jupiter, one inside Io's orbit and the
others millions of miles from the planet. Not visible is Jupiter's faint
ring of particles, seen for the first time by Voyager 1.

and part of description from NASA/JPL press release photo #79-H-97 (P21181C).This image of Jupiter was taken by Voyager 1 on March 1, 1979, from a distance of 4.3 million kilometers (2.7 million miles). The image shows Jupiter's Great Red Spot (top) as well as one of the white ovals that can be seen from Earth in Jupiter's atmosphere. The Great Red Spot is large enough that the Earth could just fit inside it.

#P21457.This full disk image of Jupiter's satellite Io was made from several frames taken by Voyager 1 on March 4, 1979, as the spacecraft neared the satellite. Io is about 862,000 kilometers (500,000 miles) away here. Io is the first body in the solar system (beyond Earth) where active volcanism has been observed. A variety of features can be seen in the image that appear linked to the intense volcanic activity on Io: the circular, donut-shaped feature in the center has been identified with a known erupting volcano; other, similar features can be seen across the face of the satellite. Io's volcanic activity appears to be of at least two general kinds - explosive eruptions that spew material into the sky as much as 250 kilometers (160 miles) high; and lava that flows from vents across the surface.
