As we age, we tend to lose touch with the natural world. Many people who migrate from remote villages to cities often lament that they rarely see the bright Milky Way since arriving in urban areas.

Several factors contribute to our inability to admire the stars in our cities, including light pollution, smog, deep space exploration activities, the expansion of the universe, urbanization, and the fast pace and high pressure of urban life.

Astronomers suggest that light pollution is one of the main reasons we cannot see the stars. Statistics reveal that 80% of the world's population is in danger of light pollution due to the increase in global industrialization.

More than one-third of the world's population cannot see the Milky Way at all, particularly in developed countries such as the United States, and Japan.

Rapid industrial development in these countries has led to the deterioration of air and light pollution, even though many environmental protection measures have been taken. Light pollution has reached a critical stage, leaving many people unable to see the Milky Way they long for.

In addition to light pollution, smog in urban areas can also obscure our view of the Milky Way and the starry sky. Moreover, with the advancement of science and technology, deep space exploration activities have increased. The low-Earth orbit may soon be congested with satellites and spacecraft junk, further affecting our ability to observe the stars.

The universe's expansion is another factor that limits our ability to see the Milky Way. Every star visible to us is incredibly distant from Earth, with the nearest star being 4.3 light-years away. Even so, the stars form the Milky Way, which is rarely visible now due to the universe's expansion.

The planet we live on, Earth, is constantly moving and changing in the universe. The rotation and revolution of the Earth change the position and shape of the constellations and stars in the starry sky. Additionally, the earth is continually moving and drifting in the universe, further changing our observation of the starry sky.

Urbanization is another factor contributing to our inability to appreciate the stars. As populations grow and urbanization accelerates, cities become more massive, with more buildings and artificial lights.

These factors interfere with and affect our observation of the starry sky. Moreover, the fast pace and high pressure of urban life may leave people with little time and energy to appreciate the beauty of nature.

Despite these challenges, we should not give up our love and exploration of the starry sky.

Several measures can help us appreciate the starry sky better, such as reducing light pollution through regular education and publicity campaigns, constructing more astronomical observatories and parks, and adding more green spaces and astronomical observation facilities to urban planning.

Science and technology have also provided us with advanced telescopes and detectors for deep space exploration and space exploration, giving us more opportunities to explore the universe and observe the starry sky.

Several factors contribute to our inability to admire the stars in our cities, such as light pollution, smog, deep space exploration activities, the expansion of the universe, urbanization, and the fast pace and high pressure of urban life.

Nevertheless, we should not give up our love and exploration of the starry sky. Instead, we must take measures to appreciate the starry sky better and continue exploring the universe using the tools and opportunities provided by science and technology.
