This is NGC 1514, a planetary nebula in Taurus. Planetary nebula form from a star very late in its life when it becomes unstable and sheds its outer surface, forming an expanding bubble of gas. In this case the shell is very uneven and detailed images show that it includes several sweeping loops. It has been conjectured that the central star in this case is a double and that the expanding shell of gas from one star has been contorted by its close companion. Neat stuff.
NGC 1514 is currently well placed in the evening rising in the northeast as the sky darkens.
