The nebula extends about 0.06 parsecs (0.20 light-years) from its center. [5] As early as 1974, the central star was known to be among the coolest carbon -sequence (type WC) Wolf-Rayet stars. [ 12 ] The nebula has a mass of 0.08 M ☉ [ 7 ] and an electron temperature, that is the average kinetic energy of electrons within the plasma , of 8,160 ...
NGC 588 is a prominent, giant H II ionized [5] diffuse nebula located in the outskirts of the galaxy Messier 33's spiral arms, within the Triangulum constellation. [6] [4] The nebula has two Wolf-Rayet stars, NGC 588-UIT 008 and NGC 588-MC3 and a fairly large population of main sequence stars of 2 to 20 solar masses.
NGC 1763 (also known as N11 B, LH 10 or ESO 85-EN20) is an emission nebula with an embedded star cluster in the Dorado constellation in the Large Magellanic Cloud, It is very bright, very large and very irregular.

NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
NGC 6826 (also known as Caldwell 15) is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding ...
