Stardust Brings Interstellar Dust
Scientists are of the opinion that interstellar
dust coming into our solar system, being brought in by Stardust is of great significance. The results have exceeded all expectations, according to Donald Brownlee, a University of Washington astronomy professor //who is the principal investigator, or ...

Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar
