A new report from the European Southern Observatory (ESO)<\/a>:<\/p>\n

Astronomers find missing link for water in the Solar System<\/strong><\/a><\/p>\n

\"\"<\/a>
This artist\u2019s impression shows the planet-forming disc around the star V883 Orionis. In the outermost part of the disc water is frozen out as ice and therefore can\u2019t be easily detected. An outburst of energy from the star heats the inner disc to a temperature where water is gaseous, enabling astronomers to detect it. The inset image shows the two kinds of water molecules studied in this disc: normal water, with one oxygen atom and two hydrogen atoms, and a heavier version where one hydrogen atom is replaced with deuterium, a heavy isotope of hydrogen.<\/figcaption><\/figure>\n

Using the Atacama Large Millimeter\/submillimeter Array (ALMA), astronomers have detected gaseous water in the planet-forming disc around the star V883 Orionis. This water carries a chemical signature that explains the journey of water from star-forming gas clouds to planets, and supports the idea that water on Earth is even older than our Sun.<\/p>\n

\u201cWe can now trace the origins of water in our Solar System to before the formation of the Sun<\/em>,\u201d<\/p>\n

says John J. Tobin, an astronomer at the National Radio Astronomy Observatory, USA and lead author of the study published today in Nature.<\/p>\n
