(ORDO NEWS) — A new science paper shows that other young solar systems also have plenty of water.
The authors claim that the age of water on our planet is 4.5 billion years – almost the same as that of the Earth.
The formation of the solar system begins with a giant molecular cloud. The cloud is mostly made up of hydrogen, the main component of water.
When hydrogen combines with oxygen, they react and form water ice. Heavy water containing deuterium also appears. Scientists have studied its ratio to the usual.
It showed that heavy water arose even at the birth of the solar system.
The researchers concluded that, in general, from 1 to 50 percent of the earth’s water was formed at the initial stage of the formation of the system.
