盘点2013年八大太空事件
《科技信息(山东)》2014年第3期20-21,共2页
2013年2月,一颗陨石坠落在俄罗斯车里雅宾斯克地区,产生的冲击波导致周边数百人受伤,一些建筑物遭受破坏。它是本世纪坠落在地面最大的陨石,目前,研究人员从湖底打捞到1.5米直径的陨石残骸,分析显示它是罕见的LL球粒状陨石。

陨石中发现大量氨基酸
《天文爱好者》2008年第4期31-31,共1页
卡内基大学的天文学家在两颗陨石中发现的氨基酸含量比在之前类似的陨石中发现的高10倍,这意味着早期的太阳系中含有有机物分子的团块数量要比之前认为的多得多。为了研究氨基酸,研究者们从三个非常罕见的CR球粒状陨石上取下了一些样...
