阅读下面的短文，并根据短文后的问题，按要求答题。

Astronomy is the scientific study of celestial objects such as stars, planets, comets, and galaxies, as well as the phenomena that occur outside Earth's atmosphere. It is one of the oldest natural sciences, with its origins dating back to ancient times.
The word "astronomy" comes from the Greek words "astron," meaning "star," and "nomos," meaning "law." This reflects the early focus of astronomy on studying the movements and behavior of stars.
Astronomy has evolved significantly over the years, thanks to advancements in technology. In ancient times, people relied on naked-eye observations to study celestial objects. However, the invention of the telescope in the 17th century revolutionized the field, allowing astronomers to observe objects in much greater detail.
Today, astronomers use a variety of advanced instruments and techniques to study the universe. These include space telescopes like the Hubble Space Telescope, which can capture images of distant galaxies and other celestial objects. In addition, astronomers use radio telescopes, which
detect radio waves emitted by celestial objects, and spectrographs, which analyze the light emitted or absorbed by objects.
One of the main goals of astronomy is to understand the origins and evolution of the universe. By studying celestial objects, astronomers can learn about the processes that led to the formation of galaxies, stars, and planets. They can also investigate phenomena such as supernovae, black holes, and dark matter, which remain mysterious and fascinating.
In addition to scientific research, astronomy also plays a vital role in our daily lives. Accurate astronomical measurements are necessary for purposes such as navigation, timekeeping, and communication. For example, the Global Positioning System (GPS) relies on precise timing measurements based on the positions of satellites in Earth's orbit.
