This dramatic image from January 2006 offers a peek inside a cavern of roiling dust and gas where thousands of stars are forming. The image, taken by the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope, represents the sharpest view ever taken of this region until this time, called the Orion Nebula. More than 3,000 stars of various sizes a...
2021年06月16日 Scorpius Enhanced Image Credit & Copyright: Stefan Lenz Explanation: If Scorpius looked this good to the unaided eye, humans might remember it better. Scorpius more typically appears as a few bright stars in a well-known but rarely pointed out zodiacal constellation. To get a spectacular image like this, though, one needs a good camera, a da...
This image taken with the NASA/ESA Hubble Space Telescope showcases the emission nebula NGC 2313. Emission nebulae are bright, diffuse clouds of ionized gas that emit their own light. The bright star V565 (center of the image) highlights a silvery, fan-shaped veil of gas and dust, while the right half of this image is obscured by a dense cloud of dust. Nebul...
The interaction of two doomed stars has created this spectacular ring adorned with bright clumps of gas – a diamond necklace of cosmic proportions. Fittingly known as the “Necklace Nebula,” this planetary nebula is located 15,000 light-years away from Earth in the small, dim constellation of Sagitta (the Arrow). A pair of tightly orbiting Sun-like stars pro...
在庆祝NASA哈勃太空望远镜发射31周年之际，天文学家将这个著名的天文台对准了一颗明亮 的 “名人星”，这是我们银河系中看到的最亮的恒星之一，被一团炽热的气体和尘埃包围着。 这颗名为船底座AG(AG Carinae)的恒星正在引力和辐射之间展开一场拉锯战，以避免自我毁灭。 在庆祝NASA哈勃太空望远镜发射31周年之际，天文学家将这个著名的天文台对准了一颗明亮 的 “名人星”，这是我们银河系中看到的最亮的恒星之一，被一团炽热的气体和尘埃包围着。 影像来源：NASA, ESA, STScI 围绕着这颗恒星的气体和尘埃的膨胀外壳大约有5光年宽，这相当于从这里到太阳以外最近的恒星半人马座的距离。 这个巨大的结构是在大约1万年前的一次或多次大喷发中形成的。这颗恒星的外层被吹...
This image taken by the NASA/ESA Hubble Space Telescope revisits the Veil Nebula, which was featured in a previous Hubble image release. In this image, new processing techniques have been applied, bringing out fine details of the nebula’s delicate threads and filaments of ionized gas. To create this colorful image, observations were taken by Hubble’s W...
This stunning image captures a small region on the edge of the inky Coalsack Nebula, or Caldwell 99. Caldwell 99 is a dark nebula — a dense cloud of interstellar dust that completely blocks out visible wavelengths of light from objects behind it. The object at the center of the image is a (much smaller) protoplanetary nebula. The protoplanetary nebula phase ...
The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion). The oblate shells of ESO 455-10, previously held tightly together as la...
Inside star cluster NGC 602, a star-forming region in the Small Magellanic Cloud, bright, blue, newly formed stars are blowing a cavity in this nebula,sculpting the inner edge of its outer portions, slowly eroding it away and eating into the material beyond. The diffuse outer reaches of the nebula prevent the energetic outflows from streaming away from the c...
Thousands of sparkling young stars are nestled within the giant nebula NGC 3603, one of the most massive young star clusters in the Milky Way Galaxy. NGC 3603, a prominent star-forming region in the Carina spiral arm of the Milky Way about 20,000 light-years away, reveals stages in the life cycle of stars. Powerful ultraviolet radiation and fast winds from t...
