裡面有一段還蠻有趣的
"We suggested hydrogen consumption because it's the obvious gas for life to consume
on Titan, similar to the way we consume oxygen on Earth," McKay said. "If these
signs do turn out to be a sign of life, it would be doubly exciting because it
would represent a second form of life independent from water-based life on Earth."
這裡大意是說, 如果像科學家所想的那樣, 這些生物是以 hydrogen (氣體)為生, 那等於是說
發現了一種不同於地球生物(以水為生)的生命形體.
