According to reports, the Stardust robotic spacecraft was launched in 1999. When it reached the comet before 2006, the comet flies and collects samples of the comet field 2 and lands back to Earth. The spacecraft begins to collect two trays of fish particles that may have entered solar energy in interstellar space. system.
Now, with the efforts of researchers from thousands of volunteers, scientists say that from the explosion of stars and other cosmic phenomena beyond the solar system, the dust they collect is newly collected.
Westphal said that the two particles are larger than other regions. Although this is a 4 micron spot in a very relative term, these two dust particles seem to be fluffy, like snowflakes, containing magnesium, iron, silicon. The salt minerals are called olivines, suggesting that they may come from rounds around other stars before they have been changed to interstellar travel.
Scientists hope to comb more information from the dust, but not yet complete. They say that more advanced equipment and processes need to analyze small samples without destroying them.
During this period, volunteers are trying to find other possible interstellar grains of star dust. These particles are trapped in aerosol materials called aerogels, but they affect the trajectory is so small, scientists had to recruit volunteers to help find. So far, about 30,700 star dust, claiming to be "dumplings", have collectively digitized images by scanning Stardust's translucent aerogel collectors, and there have been more than 10 billion particle searches for interstellar dust.
