Hot Rocks from Comet Wild 2
Scientists are finding surprises from analyzing tiny particles of comet dust collected by the Stardust spacecraft and returned to Earth 8 weeks ago. They had expected mostly “primitive” particles that had condensed under cool conditions in the solar nebula and been preserved in the deep freeze of space. However, some of the comet dust is made of minerals that can only be formed at high temperatures — either close to the Sun or perhaps in other planetary systems that existed...
