Hi.
I recently found that there is evidence that water exists in space.
From articles I've read , there are also "clouds" in space that carry large volumes of water in various states(vapor,ice etc.).
Now I don't know if those "clouds" would carry dust also , but if these clouds exist and they travel , what would their effect be on planets in our solar system if the clouds pass through our solar system.
I'm trying to find out about this (here is one article I'm reading http://www.nasa.gov/mission_pages/ju.../pia01639.html for example)
but if you know any evidence or if you can point me to articles I'll appreciate it really.
I ask this because I want to find out whether water clouds could've affected planets in our solar system.
-Thanks
