By contrast, this new study analyzes relatively fresh interstellar dust, and the findings may reveal insight into mysterious interstellar clouds and their relationship with our solar system. To look for potentially pristine samples of interstellar dust , scientists collected about 1, lbs.

It was collected several hundred miles from the coast of the frozen continent, near Germany's Kohnen Station. To identify the snow's components, the researchers brought it to Munich, melted it, filtered out the solids, incinerated the residue and analyzed the pattern of light it gave off. They discovered the presence of two rare, mildly radioactive isotopes : iron and manganese Isotopes of an element vary in how many neutrons they possess in their nuclei; so for example, the most naturally abundant iron isotope, iron, has 30 neutrons, whereas iron has 34 neutrons.

According to the researchers, the most likely source of the iron was a supernova , a powerful explosion from a gigantic dying star that is bright enough to briefly outshine all of the other stars in its host galaxy. Other natural ways of creating iron produce only up to one-tenth as much. However, iron and manganese also can be produced when atom fragments called cosmic rays strike interplanetary dust. Nonetheless, the researchers found a greater ratio of iron to manganese than they would have expected from this mechanism.

The researchers also investigated whether the iron came as fallout from nuclear weapons or power plants.

However, they found that the production of iron and manganese from these sources should be negligible.
