79. Dust to dust
4 months ago
A molecule associated with life on Earth originated in space, perhaps in the halo of comet Wild 2 (above) where it was collected.
This animation depicts Stardust's turbulent ride through three of more than two dozen jets that blast outward from comet Wild 2. The jets pummeled the spacecraft with about a million particles per second. Twelve particles, some larger than a bullet, penetrated the top layer of the spacecraft's protective shield.
