Water on Earth Older Than the Sun – Astonishing Discovery
Summary of the Article:
This article discusses a groundbreaking discovery made by scientists studying the young star V883 Orionis using the ALMA radio telescope. Here’s a breakdown of the key findings:
* Discovery of Heavy Water: Scientists detected signatures of heavy water (where hydrogen is replaced by deuterium) in the protoplanetary disk surrounding V883 Orionis – the first such detection in a planet-forming region.
* Ancient Water: The ratio of heavy water to regular water suggests the water molecules were formed before the star itself, surviving the turbulent process of star and planet birth.
* Water Predates the Star: This evidence indicates that the water in the protoplanetary disk is older than the star and any planets forming around it. Researchers believe this likely applies to our solar system as well.
* Origin of water Debate: The findings support the theory that water originates in the interstellar cloud before star formation, rather than being solely created within the protoplanetary disk.
In essence,the research suggests the water we drink could be older than the sun! This is a meaningful step forward in understanding the origins of water in planetary systems.
