智利沙漠中的巨型天线阵，捕捉星星的低语
High in the dry desert of Chile, there is a special place. It is very quiet and empty. Here, many big white dishes point to the sky. They look like giant ears. But they do not hear sound. They listen to invisible waves from space.
The air is very dry. There is little water vapor. Water vapor blocks the waves from space. So the dry air helps the dishes listen clearly. Also, the desert is far from cities. There are no bright lights. This makes the sky very dark and clear.
