NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .

2022年7月12日 · The bright star at the center of NGC 3132, while prominent when viewed by NASA’s Webb Telescope in near-infrared light, plays a supporting role in sculpting the surrounding nebula. A second star, barely visible at lower left along one of the bright star’s diffraction spikes, is the nebula’s source.

NGC 3132，也稱為八裂星雲或南環狀星雲 [3]，是在 船帆座 內的一個明亮並且被廣泛研究的 行星狀星雲，從可以利用的分光鏡數據，目前這個星雲仍以每秒24公里的速度在膨脹中。 與 地球 的距離估計大約是550 秒差距 或是2,000 光年。 在NGC 3132朦朧的影像中顯示有兩顆緊密靠在一起的恆星，一顆的 視星等 是10等，另一顆是16等。 行星狀星雲核心的中心可能是一顆比這兩顆恆星更暗淡的 白矮星。 這顆炙熱的中心恆星溫度大約是100,000 K，現在正吹散了外圍的氣體，並且 …

2022年7月12日 · Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. It is approximately 2,500 light-years away. Webb will allow astronomers to dig into many more specifics about planetary nebulae like this one – clouds of gas and dust expelled by dying stars.

在NGC 3132朦胧的影像中显示有两颗紧密靠在一起的恒星，一颗的 视星等 是10等，另一颗是16等。 行星状星云核心的中心可能是一颗比这两颗恒星更暗淡的 白矮星。 这颗炙热的中心恒星温度大约是100,000K，它正吹散了外围的气体，并且发射出强烈的紫外线 辐射 激发出明亮的萤光。 这是正是近NGC 3132中心区域的这颗暗淡的恒星，而不是那颗亮星创造了这个奇特却又美丽的行 …

1998年11月5日 · NGC 3132 is a striking example of a planetary nebula. This expanding cloud of gas, surrounding a dying star, is known to amateur astronomers in the southern hemisphere as the "Eight-Burst" or the "Southern Ring" Nebula.

2022年7月14日 · Explanation: Cataloged as NGC 3132 the Southern Ring Nebula is a planetary nebula, the death shroud of a dying sun-like star some 2,500 light-years from Earth. Composed of gas and dust the stunning cosmic landscape is nearly half a light-year in diameter, explored in unprecedented detail by the James Webb Space Telescope.

1998年11月5日 · NGC 3132 is a striking example of a planetary nebula. This expanding cloud of gas, surrounding a dying star, is known to amateur astronomers in the southern hemisphere as the 'Eight-Burst' or the 'Southern Ring' Nebula.

NGC 3132 (also known as the Eight-Burst Nebula because of its figure-8 appearance through small telescopes, or the Southern Ring Nebula) is a very bright, asymmetric planetary nebula of approximately 0.4 light-year across, located about 2,000 light-years away in the southern constellation Vela.

2023年6月22日 · The Southern Ring Nebula (Eight-Burst Nebula, NGC 3132) is a planetary nebula about 2,000 light-years away in the southern constellation Vela. In 2022, it became one of the first targets of NASA’s James Webb Space Telescope (JWST).
