Bok Globule

Caption

This Hubble image features dark knots of gas and dust known as "Bok globules," which are dense pockets in larger molecular clouds. Similar islands of material in the early universe could have held as much water vapor as we find in our galaxy today, despite containing a thousand times less oxygen.
