【巡天新发现：银河系从“二环”扩建到“五环”[赞啊]】The Milky Way is found to be twice as wide as previously thought, Zhao Gang, a lead astronomer at the National Astronomical Observatories of the Chinese Academy of Sciences said Tuesday at a press conference introducing discoveries by the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) in its first stage of spectroscopic surveys. For decades, the radius of the galaxy was believed to be about 50,000 light years. However, astronomers from the National Astronomical Observatories have found that it could reach at least 100,000 light years based on the latest data from the LAMOST this year, Zhao said. A giant star, identified as the most lithium-rich star ever known, has also been found with the help of the telescope. The device, which will start the second stage of its five-year spectroscopic surveys this September, is expected to further enrich our understanding of the galaxy and help scientists in the search for Earth-like exoplanets and extraterrestrial life, according to Zhao.

#哥本哈根减肥法打卡[超话]# day11。早起净重49.6kg。今天很虐，午饭一杯果汁和一杯低脂无糖酸奶，晚饭一丝丝肉星子都没有，不提也罢。身体已经适应食谱了，没有严重的饥饿感，但依然无比惦记碳水化合物。去逛了超市，大部分时候是巴巴地看了几眼以前最爱吃的零食，摸一摸，感受感受，然后默默放下。感觉再减下去就该参破人森了。哎。还剩两天。ps：除了食谱，我还吃了大量蓝莓，拌海带，维c，润肠保健品，fiber powder。
