A new study suggests that water was abundant in the early Universe, potentially allowing for the formation of life just 100 to 200 million years after the Big Bang. Astronomers modeled the explosions of early stars and found that these stellar deaths could have greatly enriched molecular clouds with water. This challenges the previous understanding that water became more common over time.
Water is the essence of life. Every living thing on Earth contains water within it. The Earth is rich with life because it is rich with water.
Because of its origin, we've generally thought that oxygen grew in abundance over time. From the first stars to the present day, each generation cast oxygen into space in its dying moments. The youngest and most metal-rich stars, such as the Sun, are called Population I. Older stars with fewer metals are Population II. The oldest stars, the very first stars to appear in the Universe, are known as
Based on simulations, these stars would have greatly enriched the environment with water. The molecular clouds formed from the remnants of these stars had 10 to 30 times the water fraction of diffuse molecular clouds seen in the Milky Way today.

Early Universe Water Abundance Challenged: Did the First Stars Seed Life?A new study suggests that water, a key ingredient for life, may have been abundant in the early Universe, earlier than previously thought. The study challenges the conventional understanding that water abundance increased gradually over time. By modeling the explosions of early stars, the researchers found that these stars, particularly massive ones, would have released significant amounts of water into the interstellar medium. This water enrichment could have created the conditions for life to emerge as early as 100-200 million years after the Big Bang.
