Stonehenge was extensively rebuilt in about 1902. Many of the fallen stone pillars were set upright in concrete. So what you see today is not that old,
Greek, Roman and Egyptian structures are built of stone and suffer only minor earthquake damage.
You can get a good photo of Jupiter with a cheap digital camera on maximum zoom (x16) and viewed on maximum zoom (x16=x256). All cameras have automatic jitter control. More interesting is if one of the large satellites like Io or Europa happen to be transiting Jupiter. The English navy thought about using this as a method of timekeeping before accurate chronometers.
