Galileo Gailei is the first person credited with using the telescope for astronomical observations. He did not invent the telescope. He is the first to have seen moons going around Jupiter, the rings of Saturn (though he incorrectly identified them), and that the Moon had cliffs and craters.
Galileo was the first astronomer to use a telescope to observe celestial objects in detail. This helped him make groundbreaking discoveries such as the moons of Jupiter and the phases of Venus, which provided strong evidence for the heliocentric model of the solar system.
An astronomer is a scientist who studies celestial objects such as planets and moons. They are not themselves planets or moons, but rather individuals who observe and analyze these objects as part of their work in the field of astronomy.
