Wolf-Rayet 134

This is a HOO image taken of WR134 in Cygnus.

WR 134 is a variable Wolf-Rayet star located about 6,000 light-years away in the constellation of Cygnus, and is surrounded by a faint bubble nebula blown by the intense radiation and solar wind from the star. In the image WR134 is the brightest star towards the centre of the circular blue area of nebulosity.

Wolf–Rayet stars are highly luminous objects due to their high temperatures. WR134 is bright and massive, having a radius that is five times greater than our own Sun, and about 400,000 times more luminous.

Wolf–Rayet stars, are a rare and varied set of stars, their spectra indicate very high surface enhancement of heavy elements, depletion of hydrogen, and strong stellar winds. The surface temperatures of known Wolf–Rayet stars range from 20,000 K to around 210,000 K, hotter than almost all other kinds of stars.
