Explanation:
Back in 1979, NASA's Voyager 1 spacecraft flew past Jupiter and its moons.
The images in this mosaic, featuring the moon Io against a background of gas giant
Jupiter's
diffuse swirling cloud bands,
were recorded by Voyager's camera from a distance of about 8.3 million kilometers.
The
Io image from this mosaic may be the first to show curious round features on
Io's surface
with dark centers and bright rims more than 60 kilometers across.
Now known to be volcanic in origin,
these features were then thought likely to be impact craters,
commonly seen on rocky bodies
throughout the Solar System.
But as
Voyager
continued to approach Io, close-up pictures revealed a bizarre world devoid of impact
craters, frequently resurfaced by volcanic activity.
Earlier this year a new robotic spacecraft,
NASA's Juno, began to orbit Jupiter and last week
made
a pass within 5,000 kilometers of Jupiter's clouds.
During the next two years, it is hoped that
Juno will discover new things about Jupiter, for example
what's
in Jupiter's core.
