This is an image of the spectrum of NGC7027 captured with a spectrometer, along with a wavelength intensity distribution graph created from it. The profile shows the Balmer series from Hα to Hγ, which originate from hydrogen atoms typically observed in planetary nebulae, as well as two prominent O III emission lines from ionized oxygen atoms. In addition, numerous weaker ionized spectra are present. NGC7027 is an extremely young planetary nebula and has been actively studied from the perspective of stellar evolution.
