Earth's April showers include the Lyrid Meteor Shower, observed for more than 2,000 years when the planet makes its annual passage through the dust stream of long-period Comet Thatcher. A grain of that comet's dust, moving 48 kilometers per second at an altitude of 100 kilometers or so, is swept up in this night sky view from the early hours of April 21. Flashing toward the southeastern horizon, the meteor's brilliant streak crosses the central region of the rising Milky Way. Its trail points back toward the shower's radiant in the constellation Lyra, high in the northern springtime sky and off the top of the frame. Both of the Milky way and dazzling Lyrid meteor are beautifully refflected in the calm waters of Manasi salt lake, Xinjiang, China.
Northern light from China. 在新疆拍到了极光爆发！ 真是十年一遇的机会都被我碰到了，特别把这份幸运分享给你！ 这次极光来自于日冕物质抛射引起的G-4级超强地磁暴，强度达到恐怖的KP=8。 我12点出发去克拉玛依北部追光，在凌晨3点，极光突然出现在北部天空中，达到肉眼可见的亮度。更难得的是，除了红色和紫色外，还捕捉到了通常只有在北极圈内才容易观测到的绿色极光，或属我国首次拍摄记录。 #aurora #northernlight
Aurora over China ! Captured at 4 AM in this morning. It's a dream view of mine for 10 years. #twanight
Stargazing at Huanglong Scenic and Historic Interest Area, a world heritage site located at Sichuan Province of China. The Huanglong valley is made up of snow-capped peaks and the easternmost of all the Chinese glaciers. In addition to its mountain landscape, diverse forest ecosystems can be found, as well as spectacular limestone formations, waterfalls and hot springs.
Coming back, the Gegenschein after 4 years ! Gegenschein is a rarely discernable faint glow, which can be seen 180 degrees around from the Sun along the zodiac in an extremely dark sky. The gegenschein is sunlight back-scattered off small interplanetary dust particles. These dust particles are millimeter sized splinters from asteroids and orbit in the ecliptic plane of the planets. The view was captured from Lenghu observatory at 4200m above sea level. with an extremely arid climate and unusually clear local sky. Of the nights at the site, 70 per cent have clear, photometric conditions, with a median seeing of 0.75 arcseconds. Lenghu was said to be an astronomical observation site comparable to the top ones in the world by a Nature article.
