Delle Caustiche

Astronomer Agnus Mary Clerke described a star cloud in the Sagittarius arm of the Milky Way, as “Visible to the naked eye as a dim cloudlet near Mu Sagittarii and named by Fr. Secchi as ‘Delle Caustiche’ from the peculiar arrangement of its stars in rays, arches, caustic curves and intertwined spirals.”


The lace pattern features six sided stars arranged in three arcs that kiss at the top and bottom.
