What do we learn from the news item?
Scientists have completed the largest search to date for signs of life outside of our solar system. Using a radio telescope in Australia, scientists studied around 10.3 million stars. They didn’ t find life—not yet, at least. Researchers were looking for communications signals that may come from alien beings. The search was 100 times deeper and broader than ever before, and it involved few stars in the universe. Ten million stars do seem like a lot. However, there are around 100 billion stars in the Milky Way galaxy. So they have only looked at about 0.001% of our galaxy.
选项
A、There can be as many as 100 billion stars in the universe.
B、A few communications signals from alien beings have been tracked.
C、Scientists have not found any signs of life outside of our solar system.
D、The search conducted in Australia involved stars beyond the Milky Way.
答案
C
解析
根据新闻定位句可知,迄今为止,科学家已经完成了对我们太阳系以外生命迹象的最大范围搜索,但是目前还没有发现生命。故选C。
