The Southern Delta Aquariid meteor shower of 2022 is peaking now

2022年南部三角洲水瓶座流星雨现正达到峰值

The annual Delta Aquariid meteor shower peaks tonight (July 29) through dawn on Saturday (July 30) and commonly generates about 15-20 meteors per hour at its peak.

一年一度的南部三角洲水瓶座流星雨在今晚（7月29日）至周六（7月30日）凌晨达到峰值，峰值时通常每小时产生15-20颗流星。

Look to the southeastern sky to find the meteor shower's radiant — the patch of sky where the meteors will appear to originate from — located in the constellation Aquarius.

向东南方向的天空望去，你会发现流星雨的辐射源——流星，将会出现的那片天空——位于水瓶座。

Observers in the southern tropics will get the best view as the shower's radiant, in southern Aquarius climbs higher in the sky, according to astronomer Chris Vaughan of Astrogeo.ca, who prepares Space.com's monthly Night Sky calendar in cooperation with Simulation Curriculum. Observers based at the mid-latitudes should still be able to catch a glimpse of the shower.

据《天文地理》 (Astrogeo.ca) 的天文学家 Chris Vaughan 介绍，当南部水瓶座流星雨的辐射力上升到更高的天空时，位于南部热带地区的观测者将获得最好的观赏视野。他与模拟课程 (Simulation Curriculum) 合作编写Space.com的每月夜空日历。位于中纬度的观测者应该仍然能够瞥见这场流星雨。

Unlike the upcoming Perseid meteor shower, the Southern Delta Aquariids will be uninterrupted by moonlight as the young crescent moon will have followed the sun below the horizon, leaving a dark sky perfect for meteor watching.

与即将到来的英仙座流星雨不同，南部三角洲水瓶座流星雨将不受月光的干扰，因为初成的新月将跟随太阳到地平线下，留一个黑暗的天空可以完美的观察流星。

Skywatchers should be able to see the highest number of meteors when the radiant is high in the sky at about 3 a.m. local time. The exact time of the event varies depending on your specific location, so you'll want to check out a skywatching app like SkySafari or software like Starry Night to check for times. Our picks for the best stargazing apps may help you with your planning.

当地时间凌晨3点左右，当辐射源在高空时，天文观测者应该能够看到最多的流星。该天文活动的确切时间取决于您的具体位置，所以请借助例如SkySafari这样的观星应用程序或Starry Night之类的软件来查看时间。我们挑选的最佳观星应用程序可能会帮助您制定计划。

Don't worry if you cannot make it out to catch a glimpse of the shower tonight as the Delta Aquariids are still quite active for a week surrounding the peak, according to Vaughan. The Delta Aquariids last from July 21 to August 23.

Vaughan说，如果今晚不能出去观看流星雨，也不必担心，因为三角洲水瓶座流星雨在峰值周围的一周里仍然很活跃。三角洲水瓶座流星雨将从7月21日持续到8月23日。

The Southern Delta Aquariids is caused by Comet 96P/Machholz, a periodic comet that completes an orbit around the sun every 5.24 years, according to NASA (opens in new tab). It is named after amateur astronomer Don Machholz who discovered the comet in 1986.

据美国宇航局 (NASA) 称，南部三角洲水瓶座流星雨是由96P/Machholz彗星引起的，这是一颗周期性彗星，每5.24年绕太阳运行一周（在新标签中打开）。该彗星以业余天文学家Don Machholz的名字命名，他在1986年发现了这颗彗星。

When you sit back and enjoy a meteor shower you're seeing pieces of comet debris heat up as they enter Earth's atmosphere and burn up in a bright burst of light, streaking a vivid path across the sky.

当您坐下来欣赏流星雨时，会看到彗星碎片在进入地球大气层时升温，并燃烧成一道明亮的光，在天空中划出一条生动的轨迹。
