《大西洋月刊》(www.theatlantic.com )的“In Focus”专栏,是原《波士顿大图》的编辑,美国历史学家Alan Taylor于2011年转投《大西洋月刊》之后创办的。Taylor保持了他的一贯风格,继续以现场照片专辑的方式,从不同角度反映着热点新闻,成为新的全球著名图片新闻网站。
关于《大西洋月刊》“In Focus”专栏介绍,详见http://www.theatlantic.com/infocus/pages/about/
注:《大西洋焦点月刊》很久没有发布天文图片了,这一组图片都是近期所拍,反映了全球近期热门的天文图片的集合。翻译加入一些原文没有的内容(网络搜集),以使人们阅读时,了解基础背景知识。
Robotic probes launched by NASA, the European Space Agency (ESA), and others are gathering information all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn -- and one new rover recently landed on Mars. Several others are on their way to smaller bodies, and a few are heading out of the solar system entirely. Although the Space Shuttle no longer flies, astronauts are still at work aboard the International Space Station, performing experiments and sending back amazing photos. With all these eyes in the sky, I'd like to take another opportunity to put together a recent photo album of our solar system -- a set of family portraits, of sorts -- as seen by our astronauts and mechanical emissaries. This time, we have some great shots from the new Mars rover Curiosity, a parting shot of the asteroid Vesta, some glimpses of Saturn and its moons, and lovely images of our home, planet Earth. NASA、欧洲航天局等机构发射的机器人探测器正在绕着太阳系飞行并收集信息,目前,我们已经有太空飞行器围绕着太阳、水星、金星、火星和土星等。其中最近的是一个是火星探测器好奇号。
人类的这些太空眼睛发送回来很多令人震撼的图片,这一组图片是最新的清晰太阳系照片,其中包括了好奇号发回来的火星图片。
On August 31, 2012, a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth's magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3. (NASA/GSFC/SDO)
2012年8月31日,太阳日冕,这次巨大的日冕喷发,速度达到每秒900英里,虽然不是直接冲向地球,但是对地区磁场仍有巨大影响,并在9月3日晚上引发极光这一天文现象。日冕物质抛射,又称CME,
美国宇航局太阳动态观测卫星 (SDO)拍摄的这张图片史无前例地详尽展示了一条很长、长鞭形状的太阳暗条,这一太阳暗条在太阳表面延伸有50万英里以上。 |
