A time-lapse image makes stars appear to whirl above an illuminated trilithon at Stonehenge. The monument's earliest and largest megaliths are made of immense blocks of locally available sandstone called sarsen. Other configurations within the site are made using smaller igneous slabs called bluestone, some of which weigh 4 tons and had to be hauled about 153 miles (246 kilometers) from the Preseli mountains in southern Wales.
