Galaxies, stars, exoplanets, and interstellar dust clouds are prime candidates to be studied in near infrared light. This type of light can penetrate better through dust and gas clouds, allowing astronomers to observe objects that are obscured in visible light. Additionally, studying celestial objects in the near infrared can provide insights into their temperature, composition, and physical properties.
The stars , the moon , the planet, the sun, and many other objects in the sky are called celestial objects. If you double-click on the word celestial you will get the definition and a bunch of examples.
Have you heard of astronomy? It is a natural science and the study of celestial objects. So it is like phenomenal science beyond Earth. Stars are studied as part of astronomy so in a way stars are part of science.
Astronomy as a scientific field was born out of early civilizations' observations of celestial bodies and their movements. Ancient astronomers such as the Babylonians and Greeks studied the stars, planets, and the motion of celestial objects, which laid the foundation for modern astronomy. Over time, developments in technology, such as the invention of the telescope, further advanced our understanding of the universe.

Archaic models are studied only to understand the evolution of human thought.
The Maya studied astronomy, calendrics, agriculture, and the movements of celestial bodies from observation. They built impressive observatories and used their knowledge to develop sophisticated calendars and accurately predict celestial events.
The Aztecs studied astronomy, mathematics, agriculture, medicine, and art. They had a complex understanding of the movements of celestial bodies, developed a sophisticated calendar system, and created intricate pottery and sculptures. Additionally, they had advanced knowledge of botany and herbal medicine.
Black holes are distant objects found usually in the center of galaxies; therefore they are studied by astronomers, using telescopes, just as all astronomical objects are studied. Of course, black holes are studied indirectly. They do not emit radiation (or not enough radiation to view; there is Hawking radiation) but they have a strong effect on other nearby objects, which can be observed.
