Wolf Rayet Star

WR 124 (above) is a Wolf-Rayet star in the constellation of Sagitta surrounded by a ring nebula of expelled material known as M1-67. It is one of the fastest runaway stars in the galaxy with a radial velocity around 200 km/s, and was discovered by Paul W. Merrill in 1938, identified as a high velocity Wolf Rayet star. It’s surrounded by an intensely hot nebula formed from the star’s extreme stellar wind. The nebula M1-67 is expanding at a rate of over 150,000 km/h (100,000 mph) and is nearly 6 light-years across, leading to the dynamical age of 20,000 years.
