As far as the scientific world is concerned they have no answer as yet since none of the probes sent out were capable of chemically analyze the stuff However the ESA (european space agency) has a proposal on the table to find out what galactic dust is made off (see the links below) http://www.mpi-hd.mpg.de/dustgroup/dune/content/science.htm www.mpi-hd.mpg.de/dustgroup/dune/files/proposal.pdf http://www.space.com/scienceastronomy/astronomy/dust_grain_991216.html |

A lot of information can be obtained from spectroscopy, from examining the way light is polarised and from looking at the dust's behaviour in magnetic fields. This url has some useful info - http://www.astrochem.org/DenseISM.html There's a lot of information on the web, but I didn't find pages that summarised it. Useful search terms would be ISM (Interstellar Medium), GMC (Giant Molecular Clouds) and Bok Globules. Ian G. |
