      1月3-4日: 象限仪座流星雨                               这些流星是因2003 EH1彗星的碎片产生的，碎片掉入了地球，并在进入大气层时分解。流星雨来袭期间平均每小时可以看到40个流星，流星雨将在1月3日晚上和1月4日早晨达到顶峰。
These showers are produced by debris from the extinct comet, 2003 EH1 – which fell into Earth’s path and disintegrated on entering its atmosphere. An average of 40 meteors per hour can be seen during the shower, which will peak on the night of Jan. 3 and morning of Jan. 4.




2月9号, 3月9号, 4月8号, 5月7号: 超级月亮
                              当满月与月球运行到近地点的时刻重合时，就会出现超级月亮。在这种情况下，月亮会比平时更亮更大。
A supermoon occurs when the full moon coincides with its closest approach to Earth in its orbit. On these days, the moon will appear brighter and closer than usual.



      4月22-23日: 天琴座流星雨

                              这颗流星雨是由C / 1861 G1撒切尔彗星的碎片制成的，并辐射出天琴座。平均每小时可以看到20个流星，这将在4月22日晚上和4月23日早晨达到峰值。
This meteor shower is made of debris from the comet C/1861 G1 Thatcher and radiate from the constellation Lyra. An average of 20 meteors per hour can be seen, which will peak on the night of April 22 and morning of April 23.



      6月21日: 日环食                               当月球距离地球太远而无法完全覆盖太阳时，就会发生日环食，从而在变暗的月球周围形成一束光。路径将从非洲中部开始，穿过沙特阿拉伯，印度北部，中国南部，最后到达太平洋。东非，中东和南亚的大部分地区将可以观测日环食。
This type of eclipse happens when the moon is too far away from the Earth to fully cover the sun, resulting in a ring of light around the darkened moon. The path of the eclipse will start from central Africa, proceed through Saudi Arabia, northern India, southern China and end in the Pacific Ocean. Most of eastern Africa, Middle East and southern Asia will witness a partial eclipse.
all throughout the night.

7月20日: 土星冲日                               届时，土星的位置将最靠近地球，并且会被太阳完全照亮。它会显得比平时更明亮，并且整夜都能被看到。
Saturn (C) will be positioned closest to the Earth and will be fully illuminated by the sun. It will appear brighter than it usually does and can be seen all throughout the night.

This meteor shower is produced by the debris of comets Marsden and Kracht. An average of 20 meteors per hour can be seen, which will peak on the night of July 28 and morning of July 29. The shower, that runs from July 12 to Aug. 23, will radiate out of the constellation Aquarius.

8月12-13日: 英仙座流星雨 该次流星雨在高峰期（8月12日晚上及第二天早晨）每小时最多可产生60颗流星，是由彗星Swift-Tuttle产生的。流星将从珀尔修斯星座辐射出来，并能放射出明亮的光芒。
This shower can produce up to 60 meteors per hour at its peak (night of Aug. 12 and morning of the day after), from the debris of the comet Swift-Tuttle. The meteors will radiate from the constellation Perseus and are known for producing many bright meteors.
10月7日: 天龙座流星雨
本次流星雨是由21P Giacobini-Zinner彗星碎片产生的。流星将在10月7日晚上达到顶峰，届时将以每小时约10个流星的速度辐射向天空。与其他流星雨不同，此次流星雨最好在傍晚时观看。
This minor meteor shower is produced by debris from the comet 21P Giacobini-Zinner. The meteors will radiate from the constellation Draco at a rate of about 10 meteors per hour at its peak (on the night of Oct. 7). Unlike other showers, it can be best viewed in the early evening hours

11月 4-5日: 金牛座流星雨 本次流星雨包括两个独立的流星雨，一个是由2004 TG10小行星的碎片产生的，另一个是由2P Encke彗星产生的。流星雨将在11月4日晚上达到最高峰，将从金牛座以每小时5到10个流星的速度辐射向天空。
This shower consists of two separate streams – one produced by the debris of Asteroid 2004 TG10 and the other by Comet 2P Encke. The meteors will radiate from the constellation Taurus, at a rate of five to 10 per hour, at its peak (on the night of Nov. 4).

12月 13-14日: 双子座流星雨 本次流星雨高峰时每小时将有多达120个流星，被认为是流星雨之王。流星是从名为3200 Phaethon的小行星的碎片中产生的，会从双子座中辐射出来。它将于12月13日晚上和第二天早晨达到顶峰。
With up to 120 multicolored meteors per hour at its peak, this is considered to be the king of meteor showers. Produced from the debris of an asteroid called 3200 Phaethon, meteors will radiate from the Gemini constellation. It will peak this year on the night of Dec. 13 and the morning of the next day.

12月14日: 日全食 当月亮完全阻挡太阳时，就会发生日全食，在日全食期间只有太阳发光的外部气层，也就是电晕可以被看到。智利南部和阿根廷南部的部分地区将能够看到日全食的总体路径。南美洲南部，太平洋的东南部和大西洋南部的大部分地区可以看到部分日食。
This happens when the moon completely blocks the sun, and only the outer atmosphere of the sun, known as corona, can be seen. Only parts of southern Chile and southern Argentina will be able to view the path of totality. Most parts of southern South America, southeastern Pacific Ocean and the southern Atlantic Ocean will witness a partial eclipse

12月21日: 木星和土星罕见汇合 上一次出现这种汇合现象是在2000年。两颗行星彼此之间的相距只有7弧分-彼此如此接近，看起来就像它们变成了一颗双行星。您可以在日落后的天空西方观看到此次现象。汇合的3D渲染（如图）。
This is also known as a great conjunction and last occurred in 2000. The two planets will appear only seven arc minutes of each other – so close to each other that it will look like they formed a double planet. You can view this after sunset in the western sky.
