Rising Universe, more commonly known locally as the Shelley Fountain, was a large kinetic water sculpture in Horsham, West Sussex, England. It was created by the sculptor Angela Conner and installed in 1996 to commemorate the bicentenary of the birth of the poet Percy Bysshe Shelley, who was born near Horsham. Conner refers to the work by the name Cosmic Cycle, which is the name originally attached to the work on a brass plaque. The fountain was dismantled and removed from its location in the town centre in June 2016 after district councillors voted that it had "reached the end of its serviceable life".
