Abstract

It is shown that the well known planetary nebula NGC7027 in fact is an evolved symbiotic system. Two ways of the origin of planetary nebulae are formulated. The first way: as a result of evolutionary development of mirids or OH/IR sources. The second way: as a result of dynamical interaction between the components of symbiotic system. In the second case we have very high temperature white dwarfs with accretion disks as a source of luminescence of nebula.
