An award-winning, two storey, 4.6m diameter helical staircase designed and built by UK based Webb Yates Engineers and The Stonemasonry Company.

Under construction at a house at Formby, Merseyside, each step of the apparently floating helix (secured by two post-tensioned, 12.9-millimeter steel cables running through the centre of the stairs) is formed from a single block of stone.

NASA sez:

The two light-year diameter shroud of dust and gas around a central white dwarf has long been considered an excellent example of a planetary nebula, representing the final stages in the evolution of a Sun-like star.
