well i read from a croatian science site,so if you use an translator the meaning of words will be totaly different....and no the lake isnt frozen thats the news,and they say that there might be even life underneath,becouse jupiter stretches europa in its orbit causing friction and warmth that heats up the moon melting the ice constantly,and the top layer of ice seems to serve as a protection becouse europa has no atmosphere
edit: this is the source but idk if the translator will translate the words correctly,i see that they dont work well :/
