美妙新奇的太空图片太阳磁场 Image courtesy SDO/NASA 图片来源于SDO/NASA A composite picture shows what the suns atmosphere looked like on Wednesday, as seen in three different wavelengths of light. The picture—assembled from shots taken by the Atmospheric Imaging Assembly instrument aboard NASAs Solar Dynamics Observatory—includes a model of what the suns magnetic field lines looked like at the time. 一个合成的图片展示了在上周三的太阳大气看上去是什么样子的，我们可以看到三种不同波长（亦即不同颜色）的太阳光。这个图片--由NASA的太阳动态观察中心的大气成像采集装置拍摄--展示了一个太阳磁场线在当时是什么样子的模型。One of three main instruments on the orbiting observatory, the AIA takes pictures of the sun in ten wavelengths every ten seconds. Overlaying several such images can show how magnetic events, such as prominence eruptions and coronal mass ejections, generate motion across the solar orb. 绕地飞行的观测台上三种主要仪器之一（AIA）每十秒种用十个波长来给太阳拍照。将这些影像重叠可以显示出磁场事件，是怎么样的通过太阳外围产生和运动的，比如日珥的爆发和日冕物质的大量抛射。 Tropical Storm Frank 弗兰克热带风暴 Photograph courtesy NASA/NOAA 图片来源于 NASA/NOAA Tropical storm Frank rages off the coast of Baja California, Mexico, on August 28 in a picture from NASAs unmanned Global Hawk hurricane-monitoring airplane. (Also see video of Hurricane Earl captured by astronauts.) Frank热带风暴在墨西哥下加利福尼亚海面上兴风作浪，8月28日，从NASA的无人驾驶全球鹰风暴监测飞机上拍取的图片可以清晰的看到。（也可以看由宇航员捕捉到的伯爵飓风视频） Global Hawk, which completed its first science flight earlier this year, can fly by itself for up to 30 hours, reaching altitudes of 60,000 feet (18,000 meters) and traveling as far as 11,000 nautical miles (20,000 kilometers). The robotic planes mission is to study the atmosphere over the Atlantic and Pacific Oceans with unprecedented range and endurance. 全球鹰，今年早些时候才刚刚完成其首次科学飞行，它可以自主飞行长达30个小时，最高可以到6000英尺（18000米）的高空并且可以飞行11000海里的距离（20000公里）。这个自动控制飞机的任务是研究太平洋和大西洋上空的大气情况，它有着空前的观测范围和续航能力。 We can go to regions we couldnt reach or go to previously explored regions and study them for extended periods that are impossible with conventional [piloted] planes, mission scientist David Fahey, of the National Oceanic and Atmospheric Administration, sa
