最近在多伦多北部的Lake Simcoe附近发生陨石坠落事件，恰巧被万锦一名司机的行车记录仪拍了下来，场面非常吓人，有人误以为是飞机或鸟。
图源：yorkregion 据报道，4月17日晚上约11时半，万锦一名市民驾车时看见一个明亮的火球从天而降照亮了Lake Simcoe附近的天空。他说火球就在你眼前坠落，看起来像烟花。一瞬间绿色、蓝色的光照亮了夜空。当它飞过头顶时，它变成了明亮的橙色、黄色，然后爆炸成三块。如果它真的是一个火球的话，那就太神奇了。
图源：yorkregion 天文学家认为，这是颗陨石，可能落在了Lake Simcoe东岸附近，就在Argyle的北部。火球是流星体发出的光芒，比金星还亮，而陨石是流星体经过大气层后幸存下来的碎片，降落在地面上。
图源：yorkregion Western University物理和天文学系的科学家Denis Vida证实，这次火球事件被十几台全天空照相机捕捉到，也被全球流星网络(Global Meteor Network)的几个由公民科学家操作的照相机拍到。有许多小的陨石降落在地面，最初的流星体质量被认为约为10公斤，这意味地面上可能有几十上百克的物质。 到4月19日，美国流星协会( American Meteor Society)收到了30多份关于火球在天空中飞驰的目击报告，范围从最东边的密歇根州的Ann Arbor到纽约州的Albany。 错过了这次的陨石奇观？你可以查看国际流星组织(International Meteor Organization)网站列出的下一个流星雨现象。流星雨最好在午夜后观看，能见度取决于月光的多少。 • Lyrids — April 15 to 29 (currently active); • Eta Aquariids — April 15 to May 27 (currently active), peak night May 4 to 5; • Southern Delta Aquariids — July 18 to Aug. 21, peak night July 29 to 30; • Alpha Capricornids — July 7 to Aug. 15, peak night July 30 to 31; • Perseids — July 14 to Sept. 1, peak night Aug. 11 to 12; • Orionids — Sept. 26 to Nov. 22, peak night Oct. 20 to 21; • Southern Taurids — Sept. 28 to Dec. 2, peak night Nov. 4 to 5; • Northern Taurids — Oct. 13 to Dec. 2, peak night Nov. 11 to 12 (it is expected this event will produce plenty of fireball activity); • Leonids — Nov. 3 to Dec. 2, peak night Nov. 17 to 18; • Geminids — Nov. 19 to Dec. 24, peak night Dec. 13 to 14; • Ursids — Dec. 13 to 24, peak night Dec. 21 to 22; • Quadrantids — Dec. 26 to Jan. 16, 2023, peak night Jan. 2 to 3. • Lyrids — April 15 to 29 (currently active); • Eta Aquariids — April 15 to May 27 (currently active), peak night May 4 to 5; • Southern Delta Aquariids — July 18 to Aug. 21, peak night July 29 to 30; • Alpha Capricornids — July 7 to Aug. 15, peak night July 30 to 31; • Perseids — July 14 to Sept. 1, peak night Aug. 11 to 12; • Orionids — Sept. 26 to Nov. 22, peak night Oct. 20 to 21; • Southern Taurids — Sept. 28 to Dec. 2, peak night Nov. 4 to 5; • Northern Taurids — Oct. 13 to Dec. 2, peak night Nov. 11 to 12 (it is expected this event will produce plenty of fireball activity); • Leonids — Nov. 3 to Dec. 2, peak night Nov. 17 to 18; • Geminids — Nov. 19 to Dec. 24, peak night Dec. 13 to 14; • Ursids — Dec. 13 to 24, peak night Dec. 21 to 22; • Quadrantids — Dec. 26 to Jan. 16, 2023, peak night Jan. 2 to 3. 相关链接： https://www.yorkregion.com/news-story/10611859-video-great-ball-of-fire-astronomers-believe-meteorites-landed-near-lake-simcoe/ |
