Where do you think the largest ever detected reservoir of water exists? On our home planet, dear Earth? After all, that is what makes it habitable for us, and that is what we have been searching for everywhere. We got thrilled when we found buckets of water on moon, or some ice on Mars. But now we have found water "equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away."
Think about those amounts and distances. Now, only if we could send a probe there! But wait, it says it is close to "a black hole 20 billion times more massive than the sun and produces as much energy as a thousand trillion suns." Attractive and unattainable? Maybe so!
