Space Dust

At http://phys.org/print328538416.html … the space dust in question was collected by NASAs Stardust mission in 2006, microscopic particles captured from the vicinity of a comet. Some of the conclusions are interesting – if only to show they way the minds of the researchers are taking them. Three of the particles seemed to contain sulphur compounds and some astronomers believe they should not occur in interstellar space – but apparently they do. It is hoped the dust will confirm consensus views on the origin of the solar system and possibly on the origin of life.
