Ultraviolet light heats the edges of the dark cloud, releasing gas into the relatively empty region of surrounding space.
紫外线能够加热黑云的边缘，将气体释放到周围的宇宙空间里。Still, for decades, scientists had clues that a vast cloud of antimatter lurked in space, but they did not know where it came from.
不过，数十年来，科学家们发现了表明在宇宙空间中存有大量反物质的线索，但是反物质从何而来科学家们还不知道。Nice to see at least SOMEBODY has a cogent long range plan for the exploitation of Near Space.
很高兴看到，至少有人有长期的有力计划去探索附近的宇宙空间。basically the answer was that the space shuttle and the space station are kept brightly lit , so it is difficult to see a lot of stars.
基本上来说，回答是说宇航飞船和宇宙空间站一直都很亮，所以很难看到很多星星。The menu is implemented with a simple texture, the background is just a dark space, and most graphics are bright.
这个菜单使用一个简单的纹理来实现，背景只是一个黑暗的宇宙空间，其他大多数图像是亮色的。The cores of these stars collapse, leading to a violent supernova explosion where the outer layers of the star are expelled into space.
这些恒星的核心部分塌缩导致剧烈的超新星爆发，恒星的外层物质被抛向宇宙空间。But now a pair of researchers believe extraterrestrial life could exist on a rogue planet that has been ejected from its birthplace.
但是现在有两个研究者指出，有可能有地外生物生活在漂浮星系外的星球上，这个星球从它的诞生地开始在宇宙空间中一直流浪。Terrain toward the bottom of the historic image extends to Mercury's south pole and includes a region not previously imaged from space.
在这张具有历史意义的照片下方，火星南极附近的地形清晰可见，其中包括一片此前从未从宇宙空间中拍到过的区域。The Esa-Nasa mission was the first to survey the environment in space above and below the poles of the Sun.
该欧美宇航局使命是第一次研究太阳极轴上下的宇宙空间环境。
