“消失”的璀璨星空
“消失”的璀璨星空

In the past, people needed the night sky to live.
In Australia, the Milky Way lit up the night. Aboriginal people watched stars to know when to gather food. Polynesians traveled across the Pacific Ocean by watching the stars. European sailors (水手) also used the sky to find their way. Ancient places like Stonehenge and Newgrange helped people track time. They could tell day from night clearly. People held ceremonies during the shortest days of the year.
Today, we use GPS instead of the stars. But too much light at night makes it hard for people and animals, like birds, to see the night sky.
