Seven Samples from the Solar Systemís Birth


www.astrobio.net said:

At this yearís Lunar and Planetary Science Conference (LPSC), scientists reported that, after eight painstaking years of work, they have retrieved seven particles of interstellar dust from NASAís Stardust spacecraft.

Stardust was launched in 1999 to chase the comet Wild 2. The spacecraft captured particles from the tail of the comet. The samples showed that cometary materials have undergone a great deal of alteration since the birth of the Solar System Ė such as heating and melting when comets pass near the Sun.
