Water Vapor Seen 'Raining' Onto Young Star System
tonganqn writes "Using NASA's Spitzer Space Telescope scientists have discovered huge amounts of water vapor in the young star system, called NGC 1333-IRAS 4B. From the article: 'The water vapor is pouring down from the system's natal cloud and smacking into a dusty disk where planets are thought to form. The observations provide the first direct look at how water, an essential ingredient for life as we know it, begins to make its way into planets, possibly even rocky ones like our own.'"
I can imagine large clouds of thin Oxygen and Hydrogen gas. But how do you get the gas dense enough to actually react. In those gaseous nebulas, the "gas" is nearly a vacuum. And water isn't going to come from anywhere but gaseous hydrogen and oxygen.

"Why did only one stellar embryo of 30 show signs of water? The astronomers say this is most likely because NGC 1333-IRAS 4B is in just the right orientation for Spitzer to view its dense core. Also, this particular watery phase of a star's life is short-lived and hard to catch."
IANAA. Is this a reasonable explanation?
