Explanation:
Want to go on an extraordinary voyage? Today you can, by watching Around the World in 80 Telescopes. The 24-hour long webcast is organized by the European Southern Observatory for the International Year of Astronomy cornerstone project 100 Hours of Astronomy. As suggested in this astronomically intense composite, the webcast event follows night and day around the globe to visit some of the most advanced observatories on Earth and in space, exploring the universe in visible light and beyond. The Gemini North Telescope (Hawaii, USA) and the large observatories at the summit of volcanic Mauna Kea are scheduled for the first stops in the program beginning April 3 at 09:00 UT. Others on the schedule include the Swift Satellite and Fermi Gamma-ray Space Telescope, the Himalayan Chandra Telescope (Hanle, India), and the 10-meter South Pole Telescope and IceCube Neutrino Telescope (South Pole, Antarctica). 北馆继续保持缄默，成大也哑火。我先等等吧，这个翻译内容显然是很明白的。如果21:00后翻译文章还不公布，我来翻译吧。
先预告一下，今晚CCTV10的《走近科学》也是天文100小时专题，大家不要忘记看哦！
艺术大图大家先看看。

Star Party on Planet Earth
地球上的星空饗宴

Explanation:
As twilight sweeps around planet Earth tonight (April 4), many amateur astronomers will set up their telescopes for a 24-hour global star party. The planetwide star party is part of 100 Hours of Astronomy (100HA), a project of the International Year of Astronomy 2009. To join the party, members of the public can find a nearby organized event or planned webcast by consulting the schedules on the 100HA website. What could you see through a telescope tonight? For starters, a bright Moon will shine in the evening sky, offering telescopic observers spectacular views of impact craters, mountains, and lava-flooded mare. Tonight's other celestial targets include the crowd pleasing planet Saturn surrounded by its own moons, its rings tilted nearly edge-on.
4.4，在黄昏的微光围绕地球时，许多业余天文爱好者将架起他们的望远镜开始一场全球24小时的天文聚会。这场全球性的广泛的天文交流会是天文100小时活动（简称100HA）的组成部分，后者是2009年国际天文年活动的一个项目。要加入这个活动，公众可以就近参加附近的（天文）组织活动（貌似已经太迟了——译注）或者访问100HA的网站了解本次活动的计划时间表。今晚通过望远镜你能看到什么？首先，今晚一轮明月在天，给各位使用望远镜的观测者提供月球表明清晰的环形山、山脉、月海（熔岩湖）的图像。今晚其他吸引眼球的天象是土星和它的卫星，现在土星光环几乎已经成一条线了。
明天还要去拜祭祖先，今晚的翻译估计质量不高，请大家谅解。时间表请参考上5#楼的链接。starer原意是开胃菜。——by gohomeman1 真是够呛啊，成大又不通，北馆还是慢一天。

Orange Sun Oozing
翻腾的橙色太阳

Explanation:
The Sun's surface keeps changing. Click the central arrow and watch how the Sun's surface oozes during a single hour. The Sun's photosphere has thousands of bumps called granules and usually a few dark depressions called sunspots. The above time-lapse movie centered on Sunspot 875 was taken in 2006 by the Vacuum Tower Telescope in the Canary Islands of Spain using adaptive optics to resolve details below 500 kilometers across. Each of the numerous granules is the size of an Earth continent, but much shorter lived. A granule slowly changes its shape over an hour, and can even completely disappear. Hot hydrogen gas rises in the bright center of a granule, and falls back into the Sun along a dark granule edge. The above movie and similar movies allows students and solar scientists to study how granules and sunspots evolve as well as how magnetic sunspot regions produce powerful solar flares.
太阳的表面在持续变化中。点击图中心的箭头看看太阳表面一小时的翻腾变化状况。图中的太阳光球层视野区域有数千凸起物，一般称为米粒组织；夹杂着一些小黑凹陷区域，我们称为太阳黑子。本录像中心的黑子编号875，摄于2006年，由西班牙加那利群岛真空塔式望远镜使用自适应光学系统拍摄，图中分辨率为纵横500km（讨厌的长句——译注）。每个米粒组织的大小相当于地球上的一个大洲，但寿命短得多。（从录像中可见看出），米粒组织在1小时内慢慢改变其形状，有些甚至已完全消失。灼热的氢气从米粒组织中心的亮区升起，接着从较暗的边缘区落回太阳。通过对上面视频以及类似视频的研究，同学们和太阳科学家可以了解米粒组织和黑子是如何演化的，并了解太阳黑子的磁场区如何产生强大的太阳耀斑。
Note: Follow the Sun today as part of 100 Hours of Astronomy
注：今天跟踪太阳活动是天文100小时的活动之一。
PS：米粒组织的得名就是因为光球层表面的变化很像米粥煮沸时表面的变化情形。这是太阳核心热量对流传导到光球表面必然会产生的现象。黑子当然也是发光的，只是相对于光球的亮度，黑子亮度低。在自适应光学系统全面降低太阳亮度后，就变成黑色了。
——没辙了，我自己翻译吧。北馆是不指望了，成大摆明4.5是不翻译了。4.6的都已经出了。gohomeman1 本帖最后由 gohomeman1 于 2009-4-6 22:03 编辑
昏倒，4.5的APOD使用了一个别人都不用的flashplayer，怪不得成大 都不肯翻译了。本图是我从APOD上截图再上传的。原网址在此：

经过分析网页源文件，我把这个flash文件给找出来了，原来还是flv文件，10.4MB
http://www.astro.physik.uni-goettingen.de/outreach/APOD/cont.flv
文件较大，我就不嵌入flash文件了。下载速度倒很快，但要等待一段无响应时间。上传10MB文件也比较麻烦，大家还是下载吧。 LZ还真是辛苦了，一个帖子分析的这么透彻 呵呵，如果不是它采用了特殊播放方式，本来可以直接下载那个flash文件的。不过这样就得上传10MB文件了，而且我还说不清flv文件来源，不是又麻烦了吗。
