What is the quasar water vapor cloud?

追加: 2026-05-07

[00:00:00]12 billion light years away, a rapidly growing supermassive black hole is surrounded by the largest reservoir of water ever discovered. This quasar, designated APM 08279 +5255, holds a massive cloud of water vapor containing 140 trillion times more mass than all terrestrial oceans combined.

[00:00:22]Instead of liquid seas, this moisture exists as a superheated expanse spanning hundreds of light years across the galactic core. As the central singularity accreted surrounding matter in the early universe, it violently ejected intense X-ray and infrared radiation. This immense energy output acted like a cosmic furnace, bathing the surrounding molecular gas and dust in extreme heat. Under these turbulent conditions, oxygen and hydrogen atoms were forced to bond, forging an unimaginable amount of water vapor. The sheer scale of this phenomenon proves that water is not a rare planetary feature confined to quiet habitable worlds. It is a fundamental cosmic building block manufactured in staggering abundance around the most violent and energetic objects in existence.
