[漢羅] DART 衝擊實驗 噴出來 ê 雲煙

你若是 kā 一台太空船駛去挵一粒小行星，會發生啥物代誌？ 這台就是頂禮拜去挵小行星 Dimorphos ê NASA DART 太空船，你會當看著 足濟雲煙。 挵伊 ê 目的是欲 保護咱 ê 地球，看小行星 ê 路線是毋是會 小可仔改變。 若是會當，按呢太空中 ê 大石頭就欲挵著 地球。 影片內底 ê 雲煙實在是有夠光，大部份 ê 人攏 無想著 會按呢，所以這變做是一个研究主題矣。 有一个可能是講，這粒 170 公尺闊 ê 小行星 Dimorphos 主要是 一堆細粒石頭 ê 組合，去 hŏng 挵過了後煞散開。 這支縮時攝影影片 是 tī 南美 ê 東南海岸，屬於 法國 ê Reunion 島 面頂 ê Les Makes 天文台，開 20 分鐘久 ê 時間翕–ê。 伊是 地面有咧追蹤這个衝擊實驗 ê 其中一个天文台，上開始彼个光點是小行星 Dimorphos ê 兄弟：小行星 Didymos。 最近翕著 ê 相片表示，雙小行星系統 Didymos kah Dimorphos 嘛開始 出現 kah 彗星仝款 ê 尾溜。

[English] Expanding Plume from DART’s Impact

What happens if you crash a spaceship into an asteroid? In the case of NASA’s DART spaceship and the small asteroid Dimorphos, as happened last week, you get quite a plume. The goal of the planned impact was planetary protection – to show that the path of an asteroid can be slightly altered, so that, if done right, a big space rock will miss the Earth. The high brightness of the plume, though, was unexpected by many, and what it means remains a topic of research. One possibility is that 170-meter wide Dimorphos is primarily a rubble pile asteroid and the collision dispersed some of the rubble in the pile. The featured time-lapse video covers about 20 minutes and was taken from the Les Makes Observatory on France’s Reunion Island, off the southeast coast of southern Africa. One of many Earth-based observatories following the impact, the initial dot is primarily Dimorphos’s larger companion: asteroid Didymos. Most recently, images show that the Didymos - Dimorphos system has developed comet-like tails
