First collect dust particles outside the solar system

NASA's Stardust robot ship mission has proven to be a great success after scientists claim it brought back dust that originated outside the solar system.

"They are extremely valuable particles ," according to Space.com quoted physicist Andrew Westphal of the University of California, Berkeley (USA), who led the study since the specimens were transferred to Earth. 8 years ago.

So far, a total of 7 microscopic particles from the Stardust trap originate from interstellar space , while 30,000 Stardust @ home project participants continue to assess each picture in hopes. You can find more dust particles of this type.

The Stardust spacecraft with the mission of chasing the Wild 2 comet was launched into space in 1999 to collect dust from the comet's tail.

After 7 years, the Stardust cruise ship cabin landed in the Utah desert, bringing samples back to Earth.

Westphal expert said dust particles in interstellar space have very different shapes, with seeds like snowflakes, while other particles are broken and even evaporate while moving at high speeds. to 15km / sec, when they hit the sticky trap on the Stardust.

So far, these dust particles are quite "young" by the standards of the universe, not up to 100 million years old or even only about 50 million years.

Experts hope these precious specimens may be the remains of collapsing stars in supernova events many millions of years ago.
