银河说-每日一图171212期：冬日天象图

冬日天空的精彩时刻

今年冬天有哪些天文事件呢？该图向我们展示了一些北半球最为精彩的天文事件。图片类似于布拉格天文钟表盘，图片底部类似于表盘中间，左边展示的是初冬的天文事件，而右边展示的则是冬末的。离地球越近的天体事件，在图中越靠近中下部拿望远镜观测的卡通小人，尽管不用望远镜，我们就可以看到图中的大部分事件。今年冬天精彩的天文事件包括本周达到高峰的双子座流星雨、冬夜越发引人注目的猎户座，二月中日出之前许多可见的行星。每个季节都一样，如果你恰好知道观看的时间和地点，有时候你会看到国际空间站（ISS）在你头顶的天空中穿梭。

Highlights of the Winter Sky
Illustration Credit & Copyright: Universe2go.com

Explanation: What’s up in the sky this winter? The featured graphic gives a few highlights for Earth’s northern hemisphere. Viewed as a clock face centered at the bottom, early winter sky events fan out toward the left, while late winter events are projected toward the right. Objects relatively close to Earth are illustrated, in general, as nearer to the cartoon figure with the telescope at the bottom center — although almost everything pictured can be seen without a telescope. Highlights of this winter’s sky include the Geminids meteor shower peaking this week, the constellation of Orion becoming notable in the evening sky, and many planets being visible before sunrise in February. As true in every season, the International Space Station (ISS) can be sometimes be found drifting across your sky if you know just when and where to look.
