How do astronomers study distant stars and planets?

Astronomers study distant stars and planets by using telescopes to observe them. Telescopes can be ground-based or placed in space to capture light and images from faraway objects. They analyze the light, colors, and other signals received to learn about the stars’ composition, temperature, and distance. Additionally, they use other tools like satellites and spacecraft to explore planets and gather more information.
