Astronomers at Caltech have discovered the largest reservoir of water in the universe, located 30 billion trillion miles away in a quasar.

The water vapor is over 12 billion years old and is 140 trillion times more than all the water in Earth's oceans combined.

The quasar is powered by a massive black hole 20 billion times the Sun's mass, emitting substantial energy.

Observations of the warm and dense gas around the black hole challenge previous beliefs about the origins of water in the universe.

Advanced telescopes and spectrometers are being used to study this water distribution further.

Plans are in place to build a new telescope in Chile to explore these cosmic mysteries further.

This discovery expands our understanding of the distant cosmos and prompts a reevaluation of the origins of water in the universe.
