As in previous years, we reached out to Dean Regas, astronomer for the Cincinnati Observatory and author of "100 Things to See in the Night Sky," for some suggestions of highlights. Below are a few of his tips sprinkled with some of our own must-see skywatching events for 2020!
和往年一樣,我們聯(lián)系了辛辛那提天文臺(tái)的天文學(xué)家、《夜空100件事》一書的作者迪安·雷加斯,希望他能給我們一些精彩的建議。以下是他的一些建議,其中包括一些2020年必看的空中觀景活動(dòng)!

The last gasps of winter and early hints of spring will be presided over by a rare number of supermoons. These lunar events, which look slightly larger and brighter than usual, occur when the moon is both full and at its closest approach to Earth (perigee) for a given monthly orbit. It's estimated that the light from a supermoon is roughly 16% than a standard full moon. This year's supermoons will take place on Feb. 9, March 9, April 8 and May 7.
冬季的最后喘息和春天的初現(xiàn)跡象將由為數(shù)不多的超級(jí)月亮來(lái)主導(dǎo)。這些月球事件,看起來(lái)比平常要大一些,也要亮一些,發(fā)生在月圓的時(shí)候,也就是月亮最接近地球(近地點(diǎn))的時(shí)候。據(jù)估計(jì),超級(jí)月亮發(fā)出的光約為標(biāo)準(zhǔn)滿月的16%。今年的超級(jí)月亮將在2月9日、3月9日、4月8日和5月7日出現(xiàn)。

The first full day of summer in the Northern Hemisphere will feature a stunning annular solar eclipse for spectators in mid Africa, across the Middle East, northern India and south-east Asia.
北半球夏季的第一個(gè)全天,非洲中部、中東、印度北部和東南亞的觀眾將看到令人震驚的日環(huán)食。
Mars makes a glorious close approach (Oct. 6)
火星接近地球(10月6日)

While not quite as close as its 2018 pass, Mars' 2020 approach will still offer a spectacular view of the red planet. For much of the month of October, Mars will glow brighter than even mighty Jupiter; becoming the third-most visible object in the sky after the moon and Venus.
雖然還沒(méi)有2018年那么近,但2020年的火星計(jì)劃仍將為我們呈現(xiàn)這顆紅色星球的壯觀景象。在10月的大部分時(shí)間里,火星會(huì)比強(qiáng)大的木星還要亮;成為天空中僅次于月亮和金星的第三大可見天體。
Full 'blue' Halloween moon (Oct. 31)
萬(wàn)圣節(jié)的滿月(10月31日)

Trick or treaters on the prowl for sweets can expect a welcome assist from a haunting "blue" moon on Oct. 31. Sadly, the moon won't actually be the color blue, with the term only the second of two full moons occurring in the same calendar month. The last one occurred on March 31, 2018.
10月31日,“不給糖就搗蛋”的小搗蛋者們將會(huì)得到縈繞心頭的“藍(lán)月”的幫助。遺憾的是,月亮實(shí)際上不會(huì)是藍(lán)色的,因?yàn)檫@個(gè)術(shù)語(yǔ)只出現(xiàn)在同一個(gè)日歷月兩次滿月中的第二次。最后一次發(fā)生在2018年3月31日。
Geminids: Best meteor shower of 2020? (Dec. 14-15)
雙子座:2020年最佳流星雨?(12月14日至15日)

While the Perseid meteor shower in August is often billed as the year's best meteor shower, the conditions for the Geminids in December 2020 could give it a run at the crown. The annual shower, originating from debris left behind by the asteroid Phaethon, generally produces slow-moving meteors in excess of between 120-160 per hour.
雖然8月的英仙座流星雨經(jīng)常被宣傳為今年最好的流星雨,但2020年12月的雙子座流星雨的條件可能會(huì)給它帶來(lái)沖擊。每年一度的流星雨是由小行星法厄同留下的碎片形成的,它通常會(huì)以每小時(shí)120-160顆的速度緩慢移動(dòng)。
Total solar eclipse for Chile and Argentina (Dec. 14)
智利和阿根廷的日全食(12月14日)

If, for whatever reason, you missed out on the stunning total solar eclipse above Chile and Argentina on July 2, 2019, you won't have to wait long for the next one. On Dec. 14, 2020, the same region will experience yet another total solar eclipse –– with totality expected to cast the world into shadow for 2 minutes and 10 seconds.
如果,不管出于什么原因,你錯(cuò)過(guò)了2019年7月2日智利和阿根廷上空的令人震驚的日全食,你就不用等太久了。2020年12月14日,該地區(qū)將再次發(fā)生日全食,預(yù)計(jì)日全食將使整個(gè)世界籠罩在2分10秒的陰影中。
