   NGC 6888 (Crescent Nebula) NGC 2359 (Thor's Helmet Nebula) M1-67 (Luminous Blue Variable Nebula) NGC 3199 (Nebula around WR 18) These nebulae exhibit intricate structures revealed in visible light as well as infrared, X-ray, and other wavelengths, providing insight into the powerful stellar winds and evolutionary processes around Wolf-Rayet stars.

3. WR 140 - Wikipedia

   en.wikipedia.org/wiki/WR_140

   WR 140 is a visually moderately bright Wolf–Rayet star placed within the spectroscopic binary star, SBC9 1232, [7] whose primary star is an evolved spectral class O4–5 star. [7] It is located in the constellation of Cygnus , lying in the sky at the centre of the triangle formed by Deneb , γ Cygni and δ Cygni .

4. WR 124 - Wikipedia

   en.wikipedia.org/wiki/WR_124

   WR 124 is a Wolf–Rayet star in the constellation of Sagitta surrounded by a ring nebula of expelled material known as M1-67. [9] It is one of the fastest runaway stars in the Milky Way with a radial velocity around 200 km/s. It was discovered by Paul W. Merrill in 1938, identified as a high-velocity Wolf–Rayet star. [10]

5. NGC 2359 - Wikipedia

   en.wikipedia.org/wiki/NGC_2359

   NGC 2359 (also known as Thor's Helmet) is an emission nebula [3] in the constellation Canis Major. The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution.

6. M4-18 - Wikipedia

   en.wikipedia.org/wiki/M4-18

   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 ...

7. M1-67 - Wikipedia

   en.wikipedia.org/wiki/M1-67

   M1-67 is an ejecta nebula that surrounds the Wolf–Rayet star WR 124, which is about 6.4 kpc from Earth [2] in the constellation of Sagitta.It contains dust which is caught up in WR 124's solar wind and which absorbs much of the star's light.
