[Rick]

A torrent of water-ice cascading down on an embryonic star system may shed light on how a key ingredient for life makes its way into planets.

Writing in Nature journal, astronomers detected enough water vapour to fill Earth's oceans five times over in the collapsing nest of a young star system.

Ice pours down from the outer envelope of this forming star, vapourising as it hits the dusty disc where planets form.
