    Water vapor is raining down on a young star system, pouring from the cloud of gas and dust around the star onto the dusty disk where planets may form. In the system known as NGC 1333-IRAS 4B, the icy material found in the cloud is dropping towards the star and vaporizing as it reaches the disk. The process could show how water first shows up on planets like our own.
