Planetary nebulae, like NGC 40, were orignally thought to be associated with planets forming around a star. We now know that these glowing gas shells are the result of outbursts from a dying star. This nebula is rather bright and appears overexposed in the black and white survey image. A Hubble image of this object would be able to capture the subtle details and gorgeous structure not captured here.
