2023年12月28日 Jupiter and the Geminid Image Credit & Copyright: Gaurav Singh Explanation: For a brief moment, this brilliant fireball meteor outshone Jupiter in planet Earth’s night. The serendipitous image was captured while hunting meteors under cold Canadian skies with a camera in timelapse mode on December 14, near the peak of the Geminid meteor shower. The Geminid meteor shower, asteroid 3200 Phaethon’s annual gift, always arrives in December. Dust shed along the orbit of the mysterious asteroid causes the meteor streaks, as the vaporizing grains plow through our fair planet’s upper atmosphere at 22 kilometers per second. Of course Geminid shower meteors appear to radiate from a point in the constellation of the Twins. That’s below and left of this frame. With bright Jupiter on…
2023年12月17日 Geminids over China’s Nianhu Lake Image Credit & Copyright: Hongyang Luo Explanation: Where are all of these meteors coming from? In terms of direction on the sky, the pointed answer is the constellation of Gemini. That is why the major meteor shower in December is known as the Geminids — because shower meteors all appear to come from a radiant toward Gemini. Three dimensionally, however, sand-sized debris expelled from the unusual asteroid 3200 Phaethon follows a well-defined orbit about our Sun, and the part of the orbit that approaches Earth is superposed in front of the constellation of Gemini. Therefore, when Earth crosses this orbit, the radiant point of falling debris appears in Gemini. Featured here is a composite of many images taken a…
每年冬天，双子座流星雨掠过地球时都会照亮天空，形成夜空中最强烈的流星雨之一。现在，NASA的帕克太阳探测器提供了新的证据，证明一场剧烈的、灾难性的事件创造了双子座流星雨。
2022年12月25日 Geminids and the Mittens Image Credit & Copyright: Chuck Derus Explanation: Asteroid 3200 Phaethon’s annual gift to planet Earth always arrives in December. Otherwise known as the Geminid meteor shower, the source of the meteroid stream is dust shed along the orbit of the mysterious asteroid. Near the December 13/14 peak of the shower’s activity, geminid meteors are captured in this night skyscape, composited from 22 images of starry sky taken before the moon rose over Monument Valley in the American southwest. The bright stars near the position of the shower’s radiant are the constellation Gemini’s twin stars Castor (blue) and Pollux (yellow). As Earth sweeps through the dusty stream, the parallel meteor trails appear to radiate from a point on the sky in…
