大麦哲伦星云中的绿松石羽流

In this image from 2014, brightly glowing plumes of the Large Magellanic Cloud (LMC) appear almost like an ocean current with turquoise-tinted currents and nebulous strands reaching out into the surroundings.

This image shows part of the Tarantula Nebula’s outskirts located within the LMC, a small nearby galaxy that orbits the Milky Way and appears as a blurred blob in our skies. The Hubble Space Telescope has peeked many times into this galaxy, releasing stunning images of the whirling clouds of gas and sparkling stars.

In most images of the LMC the color is completely different to that seen here. For this image, researchers substituted the customary R filter, which selects the red light, and replaced it by a filter letting through the near-infrared light. In traditional images, the hydrogen gas appears pink because it shines most brightly in the red. Here however, other less prominent emission lines dominate in the blue and green filters.

This data is part of the Archival Pure Parallel Project (APPP), a project that gathered together and processed over 1,000 images taken using Hubble’s Wide Field Planetary Camera 2, obtained in parallel with other Hubble instruments. Much of the data in the project could be used to study a wide range of astronomical topics, including gravitational lensing and cosmic shear, exploring distant star-forming galaxies, supplementing observations in other wavelength ranges with optical data, and examining star populations from stellar heavyweights all the way down to solar-mass stars.

在这张2014年的图片中,大麦哲伦星云(LMC)的明亮羽流看起来几乎就像一股绿松石色的洋流和向周围延伸的星云束。

这张图片显示了位于LMC内的狼蛛星云外围的一部分,LMC是一个围绕银河系运行的附近小星系,在我们的天空中看起来像一个模糊的斑点。哈勃太空望远镜已经多次窥视这个星系,发布了令人惊叹的气体旋转云和闪耀恒星图像。

在LMC的大多数图像中,颜色与这里看到的完全不同。对于这幅图像,研究人员替换了传统的选择红光的R滤镜,并替换了一个允许近红外光通过的滤镜。在传统图像中,氢气呈现粉红色,因为它在红色中最亮。然而,在这里,其他不太突出的发射线在蓝色和绿色滤光片中占主导地位。

这些数据是纯粹平行档案项目(APPP)的一部分,该项目收集和处理了1,000多张使用哈勃广域行星相机2号拍摄的图像,这些图像与其他哈勃仪器并行获得。该项目中的大部分数据可用于研究广泛的天文主题,包括引力透镜和宇宙剪切、探索遥远的恒星形成星系、用光学数据补充其他波长范围内的观测,以及检查来自重量级恒星的恒星种群一直到太阳质量的恒星。
