[漢羅] 火流星 ê 光 kah 聲

是哩!毋知你敢捌聽過流星 ê 聲? 一般來講,流星實在是 傷遠 矣! 咱是無法度聽著伊 ê 聲欸。 毋閣,一粒 流星 會當產生一个 離子化 ê 軌跡,伊會當 ùi 遠方反射電波信號過來。 你若是徛 tī 適當 ê 所在,可能 to̍h 會當 tī 你 ê la-ji-ò͘ 聽著一塊仔 遠方廣播電台送過來 ê 聲,毋是 kan-na 靜態影像 爾爾。 Tī 這支 影片 內底,大粒流星 ê 軌跡,反映做聲音,ùi 遠方 ê 電波發射器送過來,去予敏感 ê 電波接受器掠著。 仝一个時間,這个 光-sûn 嘛去予 全天攝影機 翕著。 Tī 影片內底,四粒 火流星 明亮 ê 光跡 迒過天頂。 第一个火流星 ê 痕跡 tī 美國 新墨西哥州 Lamy ê 所在翕著。 紲落來,tī 每一幅靜態影像,即時影片嘛翕著每一粒 流星行過 天頂。 這馬 kā 影像 kah ùi 電波反射 ê 聲音記錄敆做伙。 Kā 流星 ê 軌跡投影 tī 地球,會當揣著伊 kah 地球 相挵 ê 地點(若是有)。 毋閣若是 kā 伊 ê 軌跡 投影轉去 天頂,to̍h 會揣著 伊 ê 老爸老母,彗星抑是小行星

[English] Meteor Fireballs in Light and Sound

Yes, but have you ever heard a meteor? Usually, meteors are too far away to make any audible sound. However, a meteor will briefly create an ionization trail that can reflect a distant radio signal. If the geometry is right, you may momentarily hear – through your radio – a distant radio station even over static. In the featured video, the sounds of distant radio transmitters were caught reflecting from large meteor trails by a sensitive radio receiver – at the same time the bright streaks were captured by an all-sky video camera. In the video, the bright paths taken by four fireballs across the sky near Lamy, New Mexico, USA, are shown first. Next, after each static frame, a real-time video captures each meteor streaking across the sky, now paired with the sound recorded from its radio reflection. Projecting a meteor trail down to the Earth may lead to finding its impact site (if any), while projecting its trail back into the sky may lead to identifying its parent comet or asteroid.
