Astronomy Picture of the Day

Not just a rock

Rocks sometimes look boring.
Some have intersting insides, like geodes, with beautiful crystalline centers and dull outsides.
Today's Astronomy pic of the day is a cross section of cosmic debris,
falling piece of asteroid, and not native to Earth.
Could these be seeds of change and evolution?
