The giant-like clouds are light-years in size. So they’re so large they sort of boggle the mind. He’s talking about huge clouds of molecules in space that collapse to form thousands of stars and planets. So we know that we’re seeing CO, and we know we’re seeing methanol, we’re detecting alcohol in space, and most importantly, water. As a gas cloud in space collapses under its own weight, Bergin said that hydrogen and oxygen molecules combine and freeze as water ice on grains of dust. He added that a lot of water, enough water to fill oceans, collects as ice in planet-forming discs that surround young stars. So the disc itself, and the cloud, will have thousands, perhaps tens of thousands of oceans of water. And a fraction of that gets incorporated into Earth-like planets. Bergin also said that the building blocks of life what scientists called pre-biotic molecules, ride along with the ice in clouds during planet formation. Now maybe they don’t have anything to do with the initial steps of life. But maybe they aided and sort of jump-started the initial steps transitioning from chemistry to biology.
