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. [2]The Southern Ring Nebula was selected as one of the five cosmic objects observed by the James Webb Space Telescope as …

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。

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.

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100,000k，現在正吹散了外圍的氣體，並且發射出強烈的紫外線 輻射激發出明亮的螢光。

2022年7月14日. Webb’s Southern Ring Nebula Image Credit: NASA, ESA, CSA, STScI, NIRCam 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 ...

1998年11月5日 · NGC 3132 is nearly half a light year in diameter, and at a distance of about 2000 light years is one of the nearer known planetary nebulae. The gases are expanding away from the central star at a speed of 9 miles per second. This image, captured by NASA's Hubble Space Telescope, clearly shows two stars near the center of the nebula, a bright ...

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.
