Have you ever seen the band of our Milky Way Galaxy? In a clear sky from a dark location at the right time, a faint band of light becomes visible across the sky. Soon after your eyes become dark adapted, you might spot the band for the first time. It may then become obvious. Then spectacular. One reason for a growing astonishment might be the realization that this fuzzy swath contains billions of stars and is the disk of our very own spiral galaxy. Since we are inside this disk, the band appears to encircle the Earth. Visible in the above image, high above in the night sky, the band of the Milky Way Galaxy arcs. The bright spot just below the band is the planet Jupiter. In the foreground lies the moonlit caldera of the volcano Haleakala, located on the island of Maui in Hawaii, USA. A close look near the horizon will reveal light clouds and the dark but enormous Mauna Kea volcano on the Big Island of Hawaii. If you have never seen the Milky Way band or recognized the planet Jupiter, this year may be your chance. Because 2009 is the International Year of Astronomy, an opportunity to look through a window that peers deep into the universe may be coming to a location near you.
(成大的翻译):说明:是否曾经见过银河？在适当的时机，从远离光害的地方看夜空，可看到这条发出暗淡辉光的亮带横跨整个天空。当眼睛适应黑暗 ，还可以看见亮带中的繁星点点，然后渐渐明显， 壮丽 。震撼人心的一个原因也许是这朦胧的亮带包含了亿万恒星，并且是我们所在的螺旋星系盘面。我们就位在这个盘面之中， 亮带就像是围绕整个地球。银河系的亮带就在上面这张美丽的图像，高挂在夜空。 银河下方的亮星是木星，被月亮所照亮的前景为Haleakala火山，就位在美国 夏威夷的茂宜岛。接近水平面之处有一抹云彩以及深色的地景，那是夏威夷大岛上的基亚山 。如果你从未见过银河或是木星 ，今年是绝佳的机会。因为2009年为国际天文年 ，开启深空之旅的机会可能就近在眼前。 |
