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 年的照片中,大麦哲伦星云 (LMC) 的明亮羽流看起来几乎就像洋流,带有绿松石色的洋流和延伸到周围环境的星云。

这张图片显示了位于 LMC 内的狼蛛星云外围的一部分,LMC 是附近的一个小星系,围绕银河系运行,在我们的天空中显示为一个模糊的斑点。哈勃太空望远镜已经多次窥视这个星系,释放出旋转的气体云和闪闪发光的恒星的惊人图像。

在 LMC 的大多数图像中,颜色与这里看到的完全不同。对于这张图片,研究人员替换了选择红光的常规 R 滤光片,并将其替换为允许近红外光通过的滤光片。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。
