2024年2月18日 Hoag’s Object: A Nearly Perfect Ring Galaxy Image Credit: NASA, ESA, Hubble; Processing: Benoit Blanco Explanation: Is this one galaxy or two? This question came to light in 1950 when astronomer Arthur Hoag chanced upon this unusual extragalactic object. On the outside is a ring dominated by bright blue stars, while near the center lies a ball of much redder stars that are likely much older. Between the two is a gap that appears almost completely dark. How Hoag’s Object formed, including its nearly perfectly round ring of stars and gas, remains unknown. Genesis hypotheses include a galaxy collision billions of years ago and the gravitational effect of a central bar that has since vanished. The featured photo was taken by the Hubble Space…
2024年2月4日 The Cone Nebula from Hubble Image Credit: Hubble Legacy Archive, NASA, ESA – Processing & Licence: Judy Schmidt Explanation: Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where natal clouds of gas and dust are buffeted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264. The Cone was captured in unprecedented detail in this close-up composite of several observations from the Earth-orbiting Hubble Space Telescope. While the Cone Nebula, about 2,500 light-years away in Monoceros, is around 7 light-years long, the region pictured here surrounding the cone’s blunted head is a mere 2.5 light-years across. In our neck…
2023年10月24日 Arp 87: Merging Galaxies from Hubble Image Credit: NASA, ESA, Hubble; Processing: Harshwardhan Pathak Explanation: This dance is to the death. As these two large galaxies duel, a cosmic bridge of stars, gas, and dust currently stretches over 75,000 light-years and joins them. The bridge itself is strong evidence that these two immense star systems have passed close to each other and experienced violent tides induced by mutual gravity. As further evidence, the face-on spiral galaxy on the right, also known as NGC 3808A, exhibits many young blue star clusters produced in a burst of star formation. The twisted edge-on spiral on the left (NGC 3808B) seems to be wrapped in the material bridging the galaxies and surrounded by a curious polar ring. Together,…
NGC 685占据了舞台的中心位置，在墨黑的背景上闪烁着微弱的恒星。这个星系显然是一个棒旋星系，它有明亮的中心棒和斑驳弯曲的旋臂。它距离我们大约5,800万光年，位于波江座。NGC 685位于天赤道以南，在一年中的某些时候从南半球可以看到。
这张NASA哈勃太空望远镜的新照片的前景是几片亮粉色和几缕暗红色。NGC 5068是一个棒旋星系，有数千个恒星形成区域和大量星际尘埃。
2023年10月6日 Edwin Hubble Discovers the Universe Image Credit & Copyright: Courtesy Carnegie Institution for Science Explanation: How big is our universe? This question, among others, was debated by two leading astronomers in 1920 in what has since become known as astronomy’s Great Debate. Many astronomers then believed that our Milky Way Galaxy was the entire universe. Many others, though, believed that our galaxy was just one of many. In the Great Debate, each argument was detailed, but no consensus was reached. The answer came over three years later with the detected variation of single spot in the Andromeda Nebula, as shown on the original glass discovery plate digitally reproduced here. When Edwin Hubble compared images, he noticed that this spot varied, and on October 6,…
