| Description: | This is an ionized hydrogen region that features a 'blister' nebula, the bubble in the bright portion of this image. The pillars at the bottom of the bright portion of this image point toward this bubble. The bright star in the middle of this bubble is responsible for blowing this bubble. Its stellar winds have formed the aforementioned pillars and cleared the cavity about the star. Click here to see this star, and the outline of the bubble it has blown. | |
