Water’s Origins Traced Back to Pre-Solar System Times by Astronomers”

Sci­en­tists have made an intrigu­ing dis­cov­ery regard­ing the ori­gins of the Solar Sys­tem’s water. 

A young star named V883 Ori­o­n­is, locat­ed 1,300 light-years from Earth, has been observed with a disk of mate­r­i­al around it that will even­tu­al­ly coa­lesce into orbit­ing plan­ets. Sci­en­tists have detect­ed water vapor in this disk along­side the oth­er gas and dust that will become part of a new world. 

This find­ing sug­gests that the water present on Earth and oth­er plan­ets in the Solar Sys­tem was present in the gaseous cra­dle from which the Sun was born. In oth­er words, water was present before the for­ma­tion of the Sun itself and played an essen­tial role in the growth of planets.

Accord­ing to astronomer John Tobin of the US Nation­al Radio Astron­o­my Obser­va­to­ry, this dis­cov­ery implies that the ori­gins of water in the Solar Sys­tem can be traced back to before the for­ma­tion of the Sun. While water is com­mon through­out the Uni­verse, it is a vital ingre­di­ent in plan­et for­ma­tion. The col­lapse of dense clumps of gas and dust under grav­i­ty leads to the for­ma­tion of stars, and the remain­ing mate­r­i­al forms a disk that feeds into the baby star. 

Plan­ets then grow from this disk, and water is thought to play a sig­nif­i­cant role in this process. Beyond the snow­line, where water vapor freezes, dust grains are coat­ed with ice, giv­ing them greater stick­i­ness to help par­ti­cles cling togeth­er in the ini­tial stages of plan­e­tary growth.

The researchers study­ing V883 Ori­o­n­is have iden­ti­fied the spec­tral sig­na­ture of water vapor in the star’s disk, pro­vid­ing a glimpse into the build­ing blocks of the planets. 

The detec­tion of water vapor, along with the iden­ti­fi­ca­tion of hydro­gen iso­tope ratios, can pro­vide valu­able insights into plan­et for­ma­tion and the ori­gins of life in the Universe.
