【APOD 2008.1.25】日环食中的棕榈树(新年快乐!)




Annular Eclipse: The Ring of Fire

Explanation: Tomorrow, a few lucky people may see a "ring of fire." That's a name for the central view of an annular eclipse of the Sun by the Moon. At the peak of this eclipse, the middle of the Sun will appear to be missing and the dark Moon will appear to be surrounded by the bright Sun. This will only be visible, however, from a path that crosses the southern Indian Ocean. From more populated locations, southern Africa and parts of Australia, most of the Moon will only appear to take a bite out the Sun. Remember to never look directly at the Sun even during an eclipse. An annular eclipse occurs instead of a total eclipse when the Moon is on the far part of its elliptical orbit around the Earth. The next annular eclipse of the Sun will take place in 2010 January, although a total solar eclipse will occur this July. Pictured above, a spectacular annular eclipse was photographed behind palm trees on 1992 January.

不求最好,只要更好。

火焰环中的棕榈树

说明:明天,一些幸运的人或许能够看到一个“火焰之环”——这个名称指的是太阳的中央被月球遮挡而形成的日环食奇观。日环食食甚之时,太阳的中央似乎会消失不见,黑暗的月亮好像被明亮的太阳所环绕。然而,这一奇景只在南印度洋的一条带状区域内可见。在人口更稠密的地方,比如南非和澳大利亚局部地区,月亮只会把太阳咬一口。要记住,千万别直接看太阳,哪怕在日食的时候也不行。日环食与日全食不同,是在月球移动到椭圆轨道上距离地球较远的位置时发生的。下次日环食将发生在20101月,不过今年7月将发生一次日全食。上图为我们呈现的是19921月出现在棕榈树后的壮观日环食。  (译/小月)
