The smaller disc is liable for the most ring constitution we see from Earth, whereas the bigger disc is answerable for good points equivalent to the wide outer loop, illuminated because the complete nebula strikes via house and collides with interstellar subject. Hubble’s View The Helix is among the brightest planetary nebulae obvious from Earth, but in addition one of many greatest because of its proximity to Earth. accordingly, its gentle is unfolded over a space better than the whole Moon. for many observers, accordingly, the way of searching for the Helix is with binoculars or a low-magnification telescope, from a domain with very darkish skies. At most sensible the nebula will appear like a hazy disc of light—professional telescopes and lengthy exposures are required to trap the complexities proven during this view from the Hubble area Telescope.
