Chinese Rocket Lights Up Night Sky in Western US
This is what's Trending Today...
People in the western United States could not believe their eyes Wednesday night when, high in the sky, a bright streak of light appeared.
Many people took photographs or made videos of the mysterious object in the sky. Within minutes, some posted their videos on social media.
The strange fireball streaks were seen in parts of Nevada, Utah and California.
Some people thought it was a meteor shower. After all, the Delta Aquarids meteor shower can be seen in many areas in the night sky this week.
But, as the U.S. Strategic Command confirmed, these bursts of light were not from small rocks traveling through outer space.

They came from a Chinese rocket re-entering Earth's atmosphere. A spokeswoman for the Strategic Command told the Associated Press that remains of the Chinese Chang-Zheng (C-Z) 7 rocket re-entered the atmosphere at around 9:36 p.m., California time.
The CZ-7 was part of China's new generation of rockets, experts say. The rocket was launched June 25. It was huge, weighing over 5 tons.
One Twitter user commenting about the event Wednesday night was Harvard astronomer Jonathan McDowell. He said it was rare for such large objects to re-enter the atmosphere.
But the CZ-7 is not the biggest object to re-enter in 2016, he noted. Part of a Russian rocket that came down over Vietnam in January was even larger.
Experts say the Chinese rocket does not present a danger to people on the ground.

而是因为中国火箭重新进入地球大气层引起的 。美国战略司令部发言人接受美联社采访时称，加州当地时间晚9点36分，中国长征7号运载火箭的残骸重新进入了大气层 。
专家表示，长征7号运载火箭是中国新一代火箭 。该火箭于6月25日发射，其体型巨大，重量超过5吨 。
哈佛大学天文学家乔纳森·麦克道尔（Jonathan McDowell）在推特上对这一事件作出评论 。他表示，如此大型的物体重新进入大气层实属罕见 。
但他指出，长征7号运载火箭并非2016年重返大气层的最大物体 。今年1月份，在越南上空坠落的俄罗斯火箭残骸更大 。
