Astronomers just discovered the largest reservoir of water ever, roughly 140 trillion times the volume of the Earth's oceans. With severe drought afflicting Africa, Asia and the southern United States, you might ask whether this offers a solution to earthly afflictions.
Alas, it is in the very distant universe, roughly 12 billion light years from Earth. So even moving at light speed (NASA's fastest spacecraft move about 20,000 times slower), it would take humans several trillion lifetimes to reach this water blob, never mind bringing it home - definitely too far for a quick trip to the well.
But it's worth taking a deeper look. The newly discovered water can teach us about the universe when it was only a fraction of its present age.
