Quadrantids: Best meteor shower of the year to arrive in days - how to see it
INDEPENDENT
The Quadrantid meteor shower could be about to set the standard for 2022 – just days after it begins.
The spectacle will light up January’s cold and dark skies with as many as 50 meteors an hour.
It will peak on 3-4 January, with the brightest moment coming just before 9pm UK time (4pm EST) on 3 January. Relative to other meteor showers, the peak is especially key: within a couple of hours, the number of meteors drops by as much as 50 per cent.
Conditions for the show are especially good this year. It arrives not long after the New Moon, meaning that the sky should be especially dark.
And as with all meteor showers, no particular expertise or equipment is required to see it. Just head out somewhere dark if possible, look up to the sky and allow your eyes to adjust, which should mean you can spot the streaks of light as they shoot across the sky.
Meteor showers happen when the Earth passes through a cloud of debris left behind by comets and asteroids. As they collide with our atmosphere, they light up, streaking across the night sky.
The Quadrantids appear when Earth moves through debris left from the near-Earth asteroid (196256) 2003 EH1.. That might be the same extinct comet that was seen by Chinese astronomers more than 500 years ago.
They get their name from the constellation Quadrans Muralis, from which they appear to emerge, and which has since been abandoned and lives on primarily through the name of the meteor shower. Nowadays, the constellation where the lights appear to come from is known as Bootes.

象限仪座流星雨可能即将成为2022年的标准--就在它开始的几天后。
Quadrantid
Quadrantid /ˈkwɒˌdræntɪd/ 表示“象限仪（座）流星”，英文解释为“any member of a meteor shower occurring annually around Jan 3 and appearing to radiate from a point in the constellation Boötes”。
meteor
meteor /ˈmiː.t̬i.ɔːr/ 表示“流星”，英文解释为“a piece of rock or other matter from space that produces a bright light as it travels through the atmosphere”

📍meteor shower 表示“流星雨”，英文解释为“an occasion when a number of meteors (= pieces of matter in space that produce a bright light as they travel) move fast across the sky at night”举个🌰：
This could be the best meteor shower that anybody alive today will ever see.
这可能是目前世人可能看到的最棒的流星雨。
The spectacle will light up January's cold and dark skies with as many as 50 meteors an hour.
这一天文奇观将点亮1月寒冷而黑暗的天空，每小时有多达50颗流星。
spectacle
spectacle /ˈspɛktəkəl/ 表示“壮观场面；壮观景象”，英文解释为“a public event or show that is exciting to watch; an exciting appearance”举个🌰：
The carnival was a magnificent spectacle.

It will peak on 3-4 January, with the brightest moment coming just before 9pm UK time (4pm EST) on 3 January. Relative to other meteor showers, the peak is especially key: within a couple of hours, the number of meteors drops by as much as 50 per cent.
它将在1月3-4日迎来峰值，最亮的时刻将在英国时间1月3日晚上9点（美国东部时间下午4点）之前出现。相对于其他的流星雨，这个峰值是特别关键的：在几个小时内，流星的数量下降50%之多。

Meteor showers happen when the Earth passes through a cloud of debris left behind by comets and asteroids. As they collide with our atmosphere, they light up, streaking across the night sky.
当地球通过彗星和小行星留下的碎片时，就会发生流星雨。当它们进入我们的大气层时，它们就会发光，在夜空中划过。

Quadrans Muralis
象限仪座（拉丁语：Quadrans Muralis）又称为四分仪座，是一个以古代用以测量星体位置的一种仪器为名的星座。1795年时天文学家拉朗德（Jérôme Lalande）将其加入了星座之列，在十九世纪的星图中，象限仪座位于武仙、天龙与牧夫座之间。著名的象限仪座流星雨即出现在本星座的区域内。但是在1920年代，国际天文联合会（International Astronomical Union, IAU）在重新制订现行的88个星座时，将象限仪座的大部分区域并入了牧夫座（Boötes），象限仪座从此成为历史名词。
Quadrans Muralis (Latin for mural quadrant) was a constellation created by the French astronomer Jérôme Lalande in 1795. It depicted a wall-mounted quadrant with which he and his nephew Michel Lefrançois de Lalande had charted the celestial sphere, and was named Le Mural in the French atlas. It was between the constellations of Boötes and Draco, near the tail of Ursa Major, containing stars between β Bootis (Nekkar) and η Ursae Majoris (Alkaid).
