We thought we knew the solar system. Apart from Earth, all the worlds out there
were dead lumps freezing in the blackness of space.
Казалось бы, о нашей Солнечной системе
ученые знали всё. Кроме Земли, на всех других космических телах ни
жизни, не тепла, ни даже света в достатке.
It was smoking gun
evidence: after billions of years out in
the cold, Io was more than still warm it was seething with volcanic activity.
За миллиарды лет, проведенных в космическом
"морозильнике", Ио не остыла, на ней буквально "кипела"
бурная вулканическая активность.
The reason for this is Io's unique position in the Jovian system. It sits closer to Jupiter
than any of the other large moons.
Here, tugged and flexed by the planet's
huge gravitational pull, as well as that
of the more distant moons Europa and Ganymede, friction keeps Io piping hot.
