The brightest stars embedded in nebulae throughout our galaxy pour out a torrent of radiation that eats into vast clouds of hydrogen gas – the raw material for building new stars. This etching process sculpts a fantasy landscape where human imagination can see all kinds of shapes and figures. This n […]
This beautiful, blushing nebula is unique amongst its counterparts. While many of the nebulae visible in the night sky are emission nebulae — clouds of dust and gas that are hot enough to emit their own radiation and light — Caldwell 4, otherwise known as the Iris Nebula or NGC 7023, is a reflection
这组图片对来自各种太空探测任务和望远镜的不同种类的光的图像进行了组合，以更好地理解宇宙。每个合成图像都包含来自钱德拉X射线天文台（Chandra X-ray Observatory）的X射线数据和其他望远镜的数据。这些图片分别显示了一系列不同的天体，包括梅西耶82星系、阿贝尔2744星系团、超新星1987A、海山二星、车轮星系和螺旋星云。 来源：NASA / CXC / SAO，NASA /STScI，NASA /JPL-Caltech / SSC，ESO /NAOJ / NRAO，NRAO /AUI / NSF，NASA /CXC / SAO / PSU和NASA /ESA 人类可以通过全球
2020年8月6日 Messier 20 and 21 Image Credit & Copyright: Emanuele Petrilli Explanation: The beautiful Trifid Nebula, also known as Messier 20, is easy to find with a small telescope in the nebula rich constellation Sagittarius. About 5,000 light-years away, the colorful study in cosmic contrasts sh
7月21日 Iron in the Butterfly Nebula Image Credit: NASA, ESA, Hubble; Processing & License: Judy Schmidt Explanation: Can stars, like caterpillars, transform themselves into butterflies? No, but in the case of the Butterfly Nebula — it sure looks like it. Though its wingspan covers over 3 l
2020年7月20日 Comet NEOWISE and Nebulae Image Credit & Copyright: Jarek Oszywa Explanation: Would you brave wild animals to photograph this sky? One astrophotographer did — and we all get to reap the rewards. First, thousands of stars were visible with many of the brightest impressively blue
This 2018 composite of the Crab Nebula was made with data from the Chandra X-Ray Observatory (blue and white), Hubble Space Telescope (purple), and Spitzer Space Telescope (pink). The star that exploded to create the Crab Nebula was first seen from Earth in 1054 A.D. Since its launch in 1999, Chandr
NASA为庆祝哈勃太空望远镜30年来揭开太空之美和神秘之处，近日公布了一幅令人震惊的新图像，展示了邻近星系的一场恒星诞生的风暴。 在这张哈勃拍摄的照片中，巨大的红色星云(NGC 2014)和它较小的蓝色邻居(NGC 2020)是位于16.3万光年之外的银河系卫星星系大麦哲伦星云中一个巨大的恒星形成区域的一部分。这幅图片之所以被称为“宇宙暗礁”是因为它看起来像海底世界。 为纪念哈勃太空望远镜观测太空30周年，NASA日前发布了一幅彩色图像，这幅图像酷似一个充满恒星的海底世界的宇宙版本。在这张哈勃拍摄的照片中，巨大的红色星云(NGC 2014)和它较小的蓝色邻居(NGC 2020)是位于16.3万
Human eyes can see only a small portion of the range of radiation given off by the objects around us. We call this wide array of radiation the electromagnetic spectrum, and the part we can see visible light. In this Hubble Space Telescope image, researchers revisited one of Hubble’s most iconi
This 2010 image from the Herschel Space Observatory shows dust clouds associated with the Rosette Nebula, a stellar nursery about 5,000 light-years from Earth in the Monoceros, or Unicorn, constellation. Herschel collected the infrared light given out by dust. The bright smudges are dusty cocoons co
