Equally stunning is the age of the water factory. The two teams of astrophysicists that found the quasar were looking out in space a distance of 12 billion light years. That means they were also looking back in time 12 billion years, to when the universe itself was just 1.6 billion years old. They were watching water being formed at the very start of the known universe, which is to say, water was one of the first substances formed, created in galactic volumes from the earliest time. Given water’s creative power to shape geology, climate and biology, that’s dramatic.
And it’s not as if this intergalactic water can be of any use to us here on Earth, of course, at least not in the immediate sense. Indeed, the discovery comes as a devastating drought across eastern Africa is endangering the lives of 10 million people in Somalia, Kenya, and Ethiopia. NASA’s water discovery should be a reminder that if we have the sophistication to discover galaxies full of water 12 billion light years away, we should be able to save people just an ocean away from drought-induced starvation.
