Gum Nebula

   Also found in: Dictionary/thesaurus, Wikipedia 0.07 sec.

Gum Nebula

Largest known emission nebula in terms of how much of the sky it occupies as seen from Earth, extending over about 35° in the southern constellations Puppis and Vela. A complex of diffuse, glowing gas too faint to see with the unaided eye, it was discovered in the 1950s. It lies roughly 1,000 light-years from Earth and may be the remnant of an ancient supernova.


Gum Nebula [′gəm ′neb·yə·lə]
(astronomy)
A giant nebula about 250 parsecs (5 × 1015miles or 8 × 1015kilometers) in diameter, with its near edge about 300 parsecs (6 × 1015miles or 9 × 1015kilometers) distant, which is both an old supernova remnant and an H II region.
