6. Tracing the rise of dust & metals in galaxies and the path of water across cosmic time to Earth and other habitable planets
The Path of Water
Trace the path of water from the ISM  molecular clouds  star-forming cores  disks  the terrestrial planet zone.

The Multi-phase ISM
What sets the balance of ISM phases?
What is the origin and lifetimes of molecular clouds?
Secret word!
