Description

The star Wolf-Rayet 134 (the brightest star near the image center) is very hot star with temperature over 63,000 K and luminosity around 400,000 times than the Sun. Its radiation and very powerful winds are the reason to form the ring shaped nebula in the mix of stellar matter and surrounding gas. Wolf-Rayet stars loose huge part of their mass in stellar winds...

WR 134 is one of the first three stars with unusual emission lines in the spectrum which lead to creation of new stars class - Wolf-Rayet stars.
