卡西尼号影像: 土星的色泽
土星占据了画面的大部分。这颗行星的大部分呈现为带状金色。一条细线(即环)呈现深褐色,从左下方斜向延伸。上部有暗带,即阴影,阴影后面是土星大气层的蓝色。有关更多详细信息,请参阅说明。

Gas and dust are shown in a deep starfield. The gas glows blue and red, while the dark dust is connected in filaments across the image. To some, the filaments appear to have the shape of two dragons fighting. Please see the explanation for more detailed information.
图中显示的是深邃星空下的气体和尘埃。气体发出蓝光和红光,而暗色的尘埃则在画面中以丝状相连。对某些人来说,细丝的形状看起来像两条龙在打斗。有关更多详细信息,请参阅说明。
2022年6月7日 NGC 6188: Dragons of Ara Image Credit & Copyright: Shaun Robertson Explanation: Do dragons fight on the altar of the sky? Although it might appear that way, these dragons are illusions made of thin gas and dust. The emission nebula NGC 6188, home to the glowing clouds, is found about 4,000 light years away near the edge of a large molecular cloud unseen at visible wavelengths, in the southern constellation Ara (the Altar). Massive, young stars of the embedded Ara OB1 association were formed in that region only a few million years ago, sculpting the dark shapes and powering the nebular glow with stellar winds and intense ultraviolet radiation. The recent star formation itself was likely triggered by winds and supernova explosions, from previous…
2020年7月28日 NGC 6188: The Dragons of Ara Image Credit & Copyright: Ariel L. Cappelletti Explanation: Dark shapes with bright edges winging their way through dusty NGC 6188 are tens of light-years long. The emission nebula is found near the edge of an otherwise dark and large molecular cloud in the southern constellation Ara, about 4,000 light-years away. Born in that region only a few million years ago, the massive young stars of the embedded Ara OB1 association sculpt the fantastic shapes and power the nebular glow with stellar winds and intense ultraviolet radiation. The recent star formation itself was likely triggered by winds and supernova explosions, from previous generations of massive stars, that swept up and compressed the molecular gas. The featured image accumulated over…
