Astronomers use instruments to observe the universe What instruments is used to observe distant stars?

Astronomers primarily use telescopes to observe distant stars. These can be optical telescopes, which capture visible light, or radio telescopes that detect radio waves emitted by celestial objects. Additionally, space-based observatories like the Hubble Space Telescope provide clearer views by avoiding Earth's atmosphere, while instruments like spectrometers analyze the light from stars to determine their composition, temperature, and motion.
