150 年前的 7 月 20 日晚,美國東部出現一長串瓦解中的流星,程度僅次於 1913 年 2 月那一次:
1860 年火流星的飛行路線由西向東超過一千英里,但沒有跌落大西洋,目擊者之一 Walt Whitman 在他的詩中這樣寫: "... strange huge meteor procession, dazzling and clear, shooting over our heads."
最近德州大學的研究報導:
Texas State astronomers solve Walt Whitman meteor mystery ---- "From all the observations in towns up and down the Hudson River Valley, we're able to determine the meteor's appearance down to the hour and minute," Olson said. "Church observed it at 9:49 p.m. when the meteor passed overhead, and Walt Whitman would've seen it at the same time, give or take one minute."
