Light pollution

Light pollution.

It's hard to spot stars now because of light pollution from our towns and cities.For example, in 1994, Los Angeles had an earthquake that caused a power cut; suddenly the city was in complete darkness. Some residents phoned the emergency services in a panic and said that they had seen a giant silvery cloud in the sky. The authorities explained that they were looking at the Milky Way galaxy.We can't see it because of the city's lights! Astronomers are concerned that they have difficulty reading and viewing activities in the sky and outer space.
