Welcome to August, a month defined by loud cicadas, pool parties, humidity and children fretting about the impending return to school. When it comes to celestial happenings, however, there's a decent list of distractions to pull you away from the fray and into the quiet beauty of gazing at the heavens. From a partial solar eclipse to a moonless evening of shooting stars, August is one of the best summer months for hitting the backyard after sundown.
歡迎來到8月,這個月充滿了蟬鳴、泳池派對、潮濕和孩子們對即將返校的焦慮。然而,當(dāng)涉及到天上發(fā)生的事情時,有一份相當(dāng)不錯的清單可以讓你分心,讓你遠(yuǎn)離爭斗,進(jìn)入凝視天空的寧靜之美。從日偏食到?jīng)]有月亮的流星之夜,八月是日落后最好的夏日月份之一。

August's two new moons will give way to dark skies for several nights. These are the perfect opportunities to grab a blanket and head outside into the still-warm summer evenings to enjoy the heavens in all their glory. With some remnants of the Perseidsstill visible, the Aug. 1 new moon will offer a chance to catch some of the faintest shooting stars.
八月的兩個新月會讓位于幾個夜晚的黑暗天空。這是一個絕佳的機會,你可以拿條毯子,走到外面溫暖的夏夜里,盡情享受天堂的壯麗。由于英仙座流星雨的一些殘跡仍然可見,8月1日的新月將提供一個機會去捕捉一些最微弱的流星。

On Aug. 9, Jupiter will be visible in the night sky less than 3 degrees from the moon. The pair will be visible to the naked eye, or you can use binoculars. But they may be too far apart for a telescope to capture them together. You'll find both near the constellation Ophiuchus.
8月9日,木星將出現(xiàn)在距離月球不到3度的夜空中。這可以用肉眼看到,也可以用雙筒望遠(yuǎn)鏡。但它們之間的距離可能太遠(yuǎn),望遠(yuǎn)鏡無法捕捉到它們,你可以在蛇夫座附近找到它們。

Regarded as one of the best celestial light shows of the year, the Perseid meteor shower occurs from July 17 to Aug. 24 and peaks on the evening of Aug. 12.
英仙座流星雨被認(rèn)為是一年中最好的天體光秀之一,它發(fā)生在7月17日至8月24日,并在8月12日晚上達(dá)到頂峰。

Now that you know about this phenomenon, choose a night or morning sometime to try and pick it out. You'll need a western or eastern horizon that's fairly unobstructed to get a clear view of our planet's huge curved shadow.
既然你已經(jīng)知道了這個現(xiàn)象,選擇一個晚上或早上的某個時間來試著找出它。你需要一個相當(dāng)暢通無阻的西方或東方地平線,才能清楚地看到我們星球巨大的弧形陰影。
