The Bubble Maker
=============
WR134 is a Wolf-Rayet star - one of the rarest and most extreme stellar types in our galaxy. A relentless stellar wind hurling matter into space at thousands of kilometres per second has, over millennia, compressed and shaped the surrounding gas into the spherical emission bubble you see here. It glows in OIII, the light of doubly ionized oxygen, set against the vast red curtain of the Cygnus H-alpha complex. Also in the field: the open cluster NGC 6883 and the double star Ξ²Β² Cygni.
What draws me to Wolf-Rayet objects is the violence made visible. This bubble is not decoration - it is the direct record of a star slowly destroying itself, pushing its own outer layers outward until they pile up and glow. WR134 will likely end as a supernova. For now, it makes bubbles.
