  2. Helix Nebula - Wikipedia

    en.wikipedia.org/wiki/Helix_nebula

    The Helix Nebula is thought to be shaped like a prolate spheroid with strong density concentrations toward the filled disk along the equatorial plane, whose major axis is inclined about 21° to 37° from our vantage point. The size of the inner disk is 8×19 arcmin in diameter (0.52 pc); the outer torus is 12×22 arcmin in diameter (0.77 pc ...

    English: This video compares a new view of the Helix Nebula acquired with the VISTA telescope in infrared light with the more familiar view in visible light from the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory. The infrared vision of VISTA reveals strands of cold nebular gas that are mostly obscured in visible light images of the ...

    Compared to the Helix Nebula, another planetary nebula in Aquarius, it is quite small. [33] NGC 7293, also known as the Helix Nebula, is the closest planetary nebula to Earth at a distance of 650 light-years. It covers 0.25 square degrees, making it also the largest planetary nebula as seen from Earth.
