230606 喷出巨大水柱!土卫二有望成为新地球?

▍原文

Astronomers have detected a huge plume of water vapour spurting out into space from Enceladus, an icy moon of Saturn.

The water stream spans some 9,600km - a distance equivalent to that of flying from the UK to Japan.

Scientists are fascinated by Enceladus because its sub-surface salty ocean - the source of the water - could hold the basic conditions to support life.
