When they saw the giant moon, both Ling Jiu and Bai Ya exclaimed.
"This is... Jupiter!"
Of the eight planets of the solar system, the ones that one could recognize at a glance was first Earth and followed straight by Saturn and Jupiter.
The characteristics of these three planets were just too obvious!
"Since that is Jupiter, isn't the planet we are standing on now Jupiter's moon?"
Bai Ya whispered. "With the hundred-kilometer-deep ocean, that is to say, this is Jupiter's second moon, Europa?"
"It's very likely!"
Ling Jiu nodded. "The scientists had speculated that the Ganymede is a satellite covered with thick ice, with a liquid ocean beneath the ice."
"Europa!"
Bai Ya was shocked. "We've just went through a wormhole and a layer of glass and we went all the way from Mars to Europa? Unbelievable!"
"It is indeed incredible!"
Ling Jiu nodded, and then said. "Let's look around?"
"Yeah!"
