木星湍流大气中的摩卡漩涡

ByNASA中文

During its 36th low pass over Jupiter, NASA’s Juno spacecraft captured this view of striking cloud bands and swirls in the giant planet’s mid-southern latitudes. The dark, circular vortex near the center of the image is a cyclone that spans roughly 250 miles (about 400 kilometers). The color at its center is likely to be the result of descending winds that cleared out upper-level clouds, revealing darker material below. 在第36次低空掠过木星时，NASA的朱诺号航天器捕捉到了这一巨行星中南纬度地区引人注目的云带和漩涡的景色。靠近图像中心的黑暗的圆形漩涡是一个气旋，其跨度大约为250英里（约400公里）。其中心的颜色可能是下降的风清除了上层云层的结果，露出了下面较暗的物质。 Citizen scientist Brian Swift used a raw JunoCam image digitally projected onto a sphere to create this view. It has been rotated so that north is up. The original image was taken on Sept. 2, 2021, at 4:09 p.m. PDT (7:09 p.m. EDT). At the time, the spacecraft was about 16,800 miles (about 27,000 kilometers)…

哈勃发现的孵化中的暗星frEGGs

ByNASA中文

This image shows knots of cold, dense interstellar gas where new stars are forming. These Free-floating Evaporating Gaseous Globules (frEGGs) were first seen in Hubble’s famous 1995 image of the Eagle Nebula. Because these lumps of gas are dark, they are rarely seen by telescopes. They can be observed when the newly forming stars ignite, their intense ultraviolet radiation eroding the surrounding gas away and letting the denser, more resistant frEGGs remain. The frEGGs seen in this image are located in the Northern Coalsack Nebula in the direction of Cygnus, the Swan. 这张图片显示了新的恒星正在形成的冷而密集的星际气体结。这些自由漂浮的蒸发气态小球（frEGG）首次出现在哈勃1995年著名的鹰状星云的图像中。因为这些气团是黑暗的，所以它们很少被望远镜看到。当新形成的恒星点燃时，它们可以被观察到，它们强烈的紫外线辐射会侵蚀周围的气体，让密度更大、抵抗力更强的frEGG保留下来。在这张图片中看到的frEGG位于天鹅座方向的北部煤袋星云中。 This Hubble image also features two giant stars. The left star is a rare, giant O-type star, which are very bright, blue-white stars known to be the hottest in the universe. These…

来自太阳的粒子在地球上产生了光影秀

ByNASA中文

The aurora borealis glow on the northern horizon while stars wheel overhead in this long exposure, taken near the Bonneville Salt Flats in Utah on Nov. 4, 2021. Sky watchers in many locations were treated to unusually intense light displays, thanks to a geomagnetic storm created when multiple coronal mass ejections (CMEs) of charged particles from the Sun interacted with Earth’s magnetic field. Of related note: the location from which this image was taken is just a few miles from the spot where capsules from the OSIRIS-REx and NASA-ESA Mars Sample Return missions are expected to land. 2021年11月4日，在犹他州邦纳维尔盐田附近拍摄的这张长时间曝光照片中，极光在北部地平线上发光，而星星在头顶上旋转。许多地方的天空观察者都看到了异常强烈的光线，这要归功于来自太阳的多个带电粒子的日冕物质抛射（CME）与地球磁场相互作用时产生的地磁风暴。与此相关的是：拍摄这张图片的地点距离OSIRIS-REx和NASA-ESA火星样本返回任务的太空舱预计着陆的地点只有几英里。 Image credit: NASA/ Bill Dunford 图片来源: NASA/ Bill Dunford

哈勃拍摄到被朦胧光环环绕的彩色行星星云

哈勃拍摄到被朦胧光环环绕的彩色行星星云

ByNASA中文

NGC 2438 is a planetary nebula, formed after the death of a Sun-like star. The medium-sized star would have expelled its outer layers of gas into space as it died, leaving behind a white-dwarf core. A halo of glowing gas over 4.5 light-years across surrounds the nebula’s brighter inner ring. Many round or nearly round planetary nebulae display these halo structures, and astronomers have been investigating how they evolve. NGC 2438 was one of the nebulae studied, and researchers found that the nebula’s halo glows due to the ionizing radiation of the central white dwarf. NGC 2438是一个行星状星云，是一颗类太阳的恒星死亡后形成。这颗中等大小的恒星在死亡时将外层气体喷射到太空中，留下一个白矮星内核。一个直径超过4.5光年的发光气体光环围绕着星云较亮的内环。许多圆形或接近圆形的行星状星云都显示出这种光环结构，天文学家一直在研究它们是如何演化的。NGC 2438是被研究的星云之一，研究人员发现这个星云的光环由于中央白矮星的电离辐射而发光。 In this color-filled image, blue represents oxygen (O III), green is hydrogen (H-alpha), orange is nitrogen (N II), and red is sulfur (S II). 在这张充满色彩的图片中，蓝色代表氧（O III），绿色代表氢（H-α），橙色代表氮（N II），红色代表硫（S…

This artists’ impression is of the Mariner 10 mission. Mariner 10, which launched on Nov. 3, 1972, was the first mission to perform an interplanetary gravity assist, using a flyby of the planet Venus to alter its path to meet Mercury. This allowed the spacecraft to meet Mercury on three occasions in 1974 and 1975. 这幅艺术家画的是水手10号的任务。水手10号于1972年11月3日发射升空，是执行行星间引力辅助任务的第一个任务，它通过飞掠金星改变路径与水星相遇。这使得宇宙飞船在1974年和1975年三次与水星会和。 Image Credit: NASA 图片来源:美国国家航空航天局
