It is about 600 years old.
For much of its history, the planetary nebula has been expelling shells, as seen in blue in the featured image.
Given its expansion rate, NGC 7027 first started expanding, as visible from Earth, about 600 years ago.
The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter.

This image from the NASA/ESA Hubble Space Telescope depicts NGC 7027, or the “Jewel Bug” nebula.
This Hubble image of NGC 6302 shows the glow of neon gas in blue, iron in red, and hydrogen in green.

NGC 7027 is one of the smallest, brightest, and most unusually shaped planetary nebulas known. For much of its history, the planetary nebula has been expelling shells, as seen in blue in the featured image.
NGC 7027 is one of the visually brightest planetary nebulae. This mass loss in NGC 7027 provided important evidence that stars a few times more massive than the Sun can avoid being destroyed in In a 6" telescope at around 50× it appears as a relatively bright bluish star.
Wide-field image of NGC 7027 (ground-based image). 286.0 KB NGC 7027 is one of the visually brightest planetary nebulae.It is unusually small, measuring only 0.2 by 0.1 light-years, whereas the typical size for a planetary nebula is 1 light-year.The expanding halo of NGC 7027 has a mass of about three times the mass of the Sun, and is about 100 times more massive than the ionized central region.
The near-ultraviolet observations will help reveal how much dust obscures the star and how hot the star really is.Planetary nebulas are expanding shells of gas created by dying stars that are shedding their outer layers. When new ejections encounter older ejections, the resulting energetic collisions shape the nebula.
Recently, NGC 7027's central star was identified in a new wavelength of light — near-ultraviolet — for the first time by using Hubble's unique capabilities. Das Objekt wurde 1878 von Édouard Stephan mit einem Teleskop der Sternwarte Marseille entdeckt. Several filters were used to sample narrow wavelength ranges.
NGC 7027 . About the Data Oktober 1794 von Sir William Herschel entdeckt. NGC 7023 ist die Bezeichnung eines den Irisnebel enthaltenden offenen Sternhaufens im Sternbild Kepheus nach Nomenklatur des NGC-Katalog.NGC 7023 hat eine Winkelausdehnung von 10' × 8'.
