When a nebula is disturbed by an outside explosion, it may form an accretion disc.
The white dwarf still has a lot of mass ( about 80% of the original star), but it only has a small size( less than two Earths). A huge volume of material forms a nebula which gradually disperses. This type of nebula is (confusingly) called a "planetary nebula".
Nebula
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).
When a nebula is disturbed by an outside explosion, it may form an accretion disc.
A star forms a nebula when it runs out of fuel. The star either becomes a red giant or a supergiant, then the star would be blown off into space either by expansion or explosion. The outer layers, which was released into space, would become a nebula, or sometimes a part of a larger nebula.
An explosion from outside the nebula
The crab nebula is the debris formed in the supernova explosion.

an explosion disturbs the dust in the nebula
An explosion disturbs the gas and dust in the nebula.
An explosion disturbs the gas and dust in the nebula.
Nebula are formed when a star explodes, releasing its gas into a gas cloud (the nebula). the nebula then will eventually condense due to gravity and form another star.
a nebula is cloud of particles which forms into a star.
