tools like radio and telescope and camera.

At the time, using a telescope to observe the night sky was a new and controversial idea. Many astronomers were skeptical of Galileo's findings and methods, preferring to rely on traditional instruments and observations. Additionally, telescopes were expensive and not widely available, which may have limited their adoption among fellow astronomers.
Astronomers use luminosity to measure the total amount of energy a star emits in all directions. By knowing a star's luminosity, astronomers can calculate its distance, size, and temperature. Luminosity helps astronomers understand the life cycle of stars and their evolution.

Telescopes
Scientists who study the Universe are called astronomers. They use telescopes and other instruments to observe and analyze celestial objects like stars, planets, galaxies, and black holes. Some astronomers also study the fundamental forces and laws that govern the Universe.

the astronomers use Absolute magnitude
Astronomers use infrared light to map the dust in between stars.
Telescopes are instruments used by astronomers. The first person to do this was Galileo.
They can be seen in telescopes and instruments can measure their light, etc.
Astronomers study stars, moons, and planets. They observe, analyze, and interpret data gathered from telescopes and other instruments to learn more about the universe.
Telescopes focus on certain objects that are not visible from the naked eye, they help astronomers develop new theories because they are able to see more, and they are instruments that help astronomers prove theories true/false.
