NGC 7027 is one of the brightest nebulae in the sky, but it has never been given a common name. In a 6-in telescope at around 50x it appears as a relatively bright bluish star. This Hubble image above shows a bit more detail.
Before being studied via Hubble, NGC 7027 was thought to be a proto-planetary nebula with the central star too cool to ionize any of the gas. It is now known to be a planetary nebula in the earliest stage of its development with a central star is believed to have been about 3 to 4 times the mass of the Sun.
