Meteors over Four Girls Mountain

Explanation: On some nights it rains meteors. Peaking over the next two nights, asteroid dust is expected to rain down on Earth during the annual Geminids meteor shower . This year, unfortunately, fainter Geminids will be harder to see because of the brightness of the Long Nights Full Moon , which occurs Wednesday. Pictured, an image from this year's Perseids meteor shower in August captured multiple streaks over Four Girls Mountain in central China . The bright Pleaides open star cluster appears toward the upper right, while numerous emission nebulas are visible in red, many superposed on the diagonal band of the Milky Way .
