Thread:Comments:Study says young stars 'shoot water bullets'/Water Bullets from Stars/reply (2)

Water from stars is news to me. Where did you learn this before 2011?

www.smithsonianmag.com/science-nature/how-did-water-come-to-earth-72037248 seems to know by 2013, with no works cited.

There is no record of our relatively young sun as an explanation how water got to the planets. Supernovae have been known to expel oxygen, a component. But water was never found in deep space. I'm not 100% sure it's been found!

Please cite one credible space source on this, from any time.
