飞机上的月食

探索宇宙（universe）！每天都会展示一张我们迷人宇宙的不同图像或照片，并附上一段由专业天文学家（astronomer）撰写的简短说明。

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

说明：你需要坐在飞机的右侧才能看到这次食（eclipse）吗？不需要。当月食（lunar eclipse）发生时，地球（Earth）面向月球（Moon）的一半区域通常都能看到，这使它们成为最常见的天文事件之一。你甚至不需要任何特殊设备就能看到它——只需用肉眼即可。月食也是最常被拍摄的天文事件之一，因为与日食（solar eclipse）不同，你的眼睛和相机不需要直视明亮的太阳。然而，考虑到上周在葡萄牙拍摄的这张精选图像，如果你在飞机起飞时坐在左侧，起初可能很难看到它。但即便如此，在起飞后，由于月食通常持续数小时，你很快就能安全地穿过过道去观看它。

Explanation: Did you need to be on the right side of this airplane to see this eclipse? No. Lunar eclipses are routinely seen from the half of the Earth facing the Moon when the eclipse occurs, making them some of the most commonly witnessed astronomical events. You don't even need any special equipment to see one -- just your unaided eyes. Lunar eclipses are also some of the most photographed astronomical events because, unlike with a solar eclipse, your eyes and camera do not have to look toward the bright Sun. However, considering the featured image taken last week from Portugal, if you were on the left side of that airplane during takeoff, you might have trouble seeing it -- at first. But even then, after takeoff, since lunar eclipses typically last for hours, you might soon be able to safely cross the aisle(s) to see it.
