There is a massive water vapor cloud floating in space so large that it could provide each person on Earth an entire planet’s worth of water—20,000 times over.
The 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. A quasar is powered by an enormous black hole that steadily consumes a surrounding disk of gas and dust. As it eats, the quasar spews out huge amounts of energy.
The cloud could supply 140 trillion planets that are just as wet as Earth is.
If the Milky Way Galaxy has about 400 billion stars, and if every one of those stars has 10 planets, each as wet as Earth, that’s only 4 trillion planets worth of water.
The new cloud of water is enough to supply 28 galaxies with water.
