Full Moon Geminids

Explanation: The dependable annual Geminid meteor shower will be near its peak tonight (December 13/14) and before tomorrow’s dawn. As Earth crosses through the dusty trail of active asteroid 3200 Phaethon the meteors will flash through the sky from the shower’s radiant in Gemini. Gemini will be pretty easy for skygazers to find too as it won’t be far from a nearly full waning gibbous Moon. You don’t have look at the shower’s radiant to see meteors though. The almost full moonlight won’t hide the brightest of the Geminids from view either, but it will substantially reduce the rate of visible meteors for those who are counting. In fact, the 2019 Geminids should look a lot like the 2016 meteor shower This composite image from the 2016 Geminids aligns individual short exposures to capture many of the brighter Geminid meteors, inspite of a Full Moon shining near the constellation of the Twins. Along the horizon are the Teide Observatory’s Solar Laboratory (right) and the Teide volcano on the Canary Island of Tenerife.

满月与双子座流星雨

说明:一年一度的双子座流星雨将在今晚(12月13日/14日)和明天黎明前接近极大期。当地球穿过第3200号活跃小行星“法厄同”的尘埃尾迹时,流星雨将从双子座内的流星雨辐射点飞出并划过天空。双子座也很容易被天文观测者发现,因为它离接近满相的亏凸月不远。然而,你不必看到流星雨的辐射点就能看到流星。满月的月光也不会遮挡双子座流星中最明亮的流星,但对于那些正在计算流星数量的人来说,它将会大大减少可见流星的数量。实际上,2019年的双子座流星雨应该看起来很像2016年的流星雨。尽管有一轮满月在双子座附近闪耀,但这幅由呈现2016年双子座流星雨的多张短曝光照片结合而成的影像还是捕捉到许多较明亮的双子座流星。沿着地平线可以看到泰德天文台的太阳实验室(影像右侧)和加那利群岛特内里费岛上的泰德火山。
