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...
2021年02月24日 Spiral Galaxy M66 from Hubble Image Credit: NASA, ESA, Hubble, Janice Lee; Processing & Copyright: Leo Shatz; Text: Karen Masters Explanation: It’s always nice to get a new view of an old friend. This stunning Hubble Space Telescope image of nearby spiral galaxy M66 is just that. A spiral galaxy with a small central bar, M66 is a member of t...
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...
Located in the constellation of Virgo (The Virgin), around 50 million light-years from Earth, the galaxy NGC 4535 is truly a stunning sight to behold. Despite the incredible quality of this image, taken from the NASA/ESA Hubble Space Telescope, NGC 4535 has a hazy, somewhat ghostly, appearance when viewed from a smaller telescope. This led amateur astronomer...
2021年01月24日 Massive Nearby Spiral Galaxy NGC 2841 Image Credit: NASA, ESA, Hubble, Subaru; Composition & Copyright: Roberto Colombari Explanation: It is one of the more massive galaxies known. A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellation of Ursa Major. This sharp view of the gorgeous island uni...
2021年01月16日 The Mountains of NGC 2174 Image Credit: NASA, ESA, Hubble Heritage Team (STScI/AURA) Explanation: This fantastic skyscape lies near the edge of NGC 2174 a star forming region about 6,400 light-years away in the nebula-rich constellation of Orion. It follows mountainous clouds of gas and dust carved by winds and radiation from the region’s n...
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...
