Kerbstone 15, a 5,000-year-old Neolithic artifact at the Knowth passage tomb in Ireland’s Boyne Valley, is carved with intricate designs including a central cupmark with 20 radiating lines, spirals, and U-shaped motifs.
One of 124 kerbstones surrounding the site’s main mound, it is part of the largest collection of megalithic art in Europe. While some researchers suggest it may represent an ancient calendar, the exact purpose of its carvings remains uncertain.

They’re formed when narrow jets of partially ionised gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometres per second.
