Go figure this one. Scientists may have identified the first specks of interstellar dust in material collected by the US space agency’s Stardust spacecraft. But, just what it would do for science? That is what I would like you to go figure out. The principle and the concept is this : A stream of this dust flows through space; the tiny particles are building blocks that go into making stars and planets. This particular Nasa spacecraft was primarily sent to catch dust streaming from Comet Wild 2 and return it to Earth for analysis. Along with that, scientists also set out to capture particles of interstellar dust. The material was gathered by the Stardust probe in a seven-year, 4.8-billion-km (2.9 billion miles) interplanetary voyage.
Now, we need to figure what all we can find out using this!
