A Chinese scientist said meteorites sold online were fake, with none found
after parts of an asteroid hit Earth near Shangri-La County in southwest China’s
Yunnan Province on Oct. 4, reported the Chinese-language newspaper Modern
Express.
据中文报纸《现代快报》报道，一名中国科学家称，10月4日，中国西南部云南省香格里拉县附近的一颗小行星部分撞击地球后，网上就开始出售的陨石都是假的，并未有任何陨石被发现。
Meteorite hunters from across the world flocked to Shangri-La following
reports of the possible hit, while some online stores lost no time putting
so-called meteorites on sale asking 8,000 to 10,000 yuan ($1,200 to $1,500) per
stone and even as much as 20,000 yuan a gram. One store claimed it offered
Martian meteorites.
随着陨石撞击地球的报道，世界各地的陨石爱好者纷纷来到香格里拉。网络上一些卖家不失时机，迅速推出了陨石叫卖，价格从8000元到1万元一颗(1200美元到1500美元)，有的甚至叫卖到了2万元1克。其中一个卖家更标明是“火星陨石”。
"Meteorites have yet to be found," said Xu Weibiao, a scientist with Purple
Mountain Observatory at the Chinese Academy of Sciences. "Moreover, 99 percent
of the meteorites sold online are fake."
中科院紫金山天文台科学家徐伟彪说，“香格里拉陨石都还没找到呢!而且，网络上叫卖的陨石99%都是假的。”
According to satellite data from NASA, an asteroid entered the atmosphere
about 40 kilometers northwest of Shangri-La, resulting in an explosion
equivalent to 540 tons of TNT, slightly stronger than the 450-ton explosion in
the Xilingele event of 2014.
根据美国国家航空航天局(NASA)的卫星数据，一颗小行星进入了香格里拉西北约40公里处的大气层，爆炸当量相当于540吨TNT，比2014年的锡林郭勒事件(450吨)略强。
Because the asteroid moved at a speed of 14.6 kilometers per second
relative to Earth and blasted apart at the relatively low altitude of about 37
kilometers, unburned meteorites and debris could have reached the ground, the
paper said.
新闻报道称，由于这颗小行星以相对地球每秒14.6千米的速度移动，在相对较低的高度37千米处爆炸，很可能有未燃尽的陨石落到地面!
But Xu said all scientists have is video footage of two explosions that
occurred during the hit and that it was hard to precisely identify the
trajectory of the asteroid. Chances are slim that any meteorites will ever be
found, Xu said, noting "it is like dredging for a needle in the sea."
不过，徐伟彪说，现在科学家手上只有记录下两次爆炸的视频，很难精确的判断出陨石的轨迹。他说，要想找到陨石，机会是很渺茫的，几乎相当于“大海捞针”。
Only after meteorites were found could they be analyzed and identified
using scientific processes, he added.
他补充说，只有找到陨石，才能通过科学手段分析、鉴别它。
But for meteorite hunters, nothing seemed impossible. Off-road vehicles,
GPS, drones and other gadgets were all used during the treasure hunt, according
to the paper.
但对于陨石爱好者来说，没有什么是不可能的。据该报报道，在寻宝过程中，越野车、GPS、无人机和其他电子设备全都派上了用场。 |
