原文:
rth’s April showers include the Lyrid Meteor Shower, observed for more than 2,000 years when the planet makes its annual passage through the dust stream of long-period Comet Thatcher. A grain of that comet’s dust, moving 48 kilometers per second at an altitude of 100 kilometers or so, is swept up in this night sky view from the early hours of April 21. Flashing toward the southeastern horizon, the meteor’s brilliant streak crosses the central region of the rising Milky Way. Its trail points back toward the shower’s radiant in the constellation Lyra, high in the northern springtime sky and off the top of the frame. The yellowish hue of giant star Antares shines to the right of the Milky Way’s bulge. Higher still is bright planet Saturn, near the right edge. Seen from Istra, Croatia, the Lyrid meteor’s greenish glow reflects in the waters of the Adriatic Sea.

🌌 在這個四月，地球的降雨故事中還有萊里的流星雨。這場流星雨已經觀察了超過 2,000 年，當地球每年通過長週期彗星撒斯的塵埃流時，就會出現它。當一顆彗星的塵埃顆粒以每秒 48 公里的速度在約 100 公里的高度飛馳時，其璀璨的瞬間劃過夜空，這幅圖片攝於四月 21 的早晨。
🌠 在轉向東南地平線的流星璀璨跡線中，流星的尾跡指向位於春天北半球的天琴座的輻射點。巨星心宿二的黃光在銀河的隆起區域右側閃耀，而更加高處的明亮行星土星靠近右側邊緣。在克羅地亞的伊斯特拉，這顆流星的綠光映照在亞得里亞海的水面上。
