On the 21st of August 1831 Slaves in Virginia revolted. Their leader, Nat Turner, was arrested, tried, and killed a few days later.
In 1999 NASA sent up a rocket, or spaceship, or probe or something to investigate a comet, the plan being that it should get close enough to scoop up some of the stuff comets are made of — stardust — and send it back to Earth.
In 2010 the first little pot of stardust came back to Earth, and since then scientists have been investigating its tiny particles.
Today, a scientific spokesman made an announcement about their findings: an astounded public was told ‘These particles are not all the same.’ He did not explain further.
