The Dumbbell Nebula

The Dumbbell Nebula -- also known as Messier 27 or NGC 6853 -- is a typical planetary nebula and is located in the constellation Vulpecula (The Fox). The distance is rather uncertain, but is believed to be around 1200 light-years. It was first described by the French astronomer and comet hunter Charles Messier who found it in 1764 and included it as no. 27 in his famous list of extended sky objects. Despite its class, the Dumbbell Nebula has nothing to do with planets. It consists of very rarefied gas that has been ejected from the hot central star, now in one of the last evolutionary stages. The gas atoms in the nebula are excited (heated) by the intense ultraviolet radiation from this star and emit strongly at specific wavelengths. In this image only light from a small wavelength range was allowed to pass and so was used to isolate emissions from particular atoms and ions. The image shows the intricate structure in the central part of the nebula.

They are three-colour composite based on two interference ([OIII] at 501 nm and 6 nm FWHM - 5 min exposure time; H-alpha at 656 nm and 6 nm FWHM - 5 min) and one broadband (Bessell B at 429 nm and 88 nm FWHM; 30 sec) filtre images, obtained on September 28, 1998, during mediocre seeing conditions (0.8 arcsec). The CCD camera has 2048 x 2048 pix, each covering 24 x 24 µm and the sky fields shown measure 6.8 x 6.8 arcmin and 3.5 x 3.9 arcmin, respectively. North is up; East is left.
