Eight Burst Nebula 소개
설명
The Eight-Burst Nebula (NGC 3132) is a bright planetary nebula in Vela, about 2,000 light-years away. Also called the Southern Ring Nebula, it spans about 1 arcminute and displays a complex, multi-layered shell structure. It was one of the first targets of the James Webb Space Telescope.
관측 팁
A fine southern planetary nebula, visible in a 4-inch telescope as a bright, slightly elongated disk. An 8-inch scope at 150x+ shows the ring structure. The central star is actually the fainter of a close pair. Best in spring from southern locations.
역사
Discovered by John Herschel in the 1830s from South Africa. JWST's 2022 images revealed at least two previously unknown concentric shells and confirmed the binary nature of the central star system.
재미있는 사실
JWST's first deep image of NGC 3132 revealed that the nebula was sculpted by at least two stars, with the dimmer companion responsible for most of the mass ejection. The brighter central star is actually a companion that did not create the nebula.
