a stethoscope
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.
I've never heard anybody use the phrase "on the sky" in any context.
Yes, human electric lighting is polluting the night sky.
Either Astronomers OR Astrologers - depending on what they are studying.
Light pollution from urban areas and artificial sources like street lights can interfere with astronomers' ability to observe celestial objects clearly. Additionally, radio waves from telecommunications and other sources can disrupt radio telescopes that astronomers use to study the universe.
He used a telescope to observe the sky. This allowed Galileo Galilei to see things that an unaided, human eye could not see.
The telescope helps astronomers the most when studying the sky.
Astronomers use mathematical calculations based on the position of other known celestial bodies to predict where Neptune should be located in the night sky. They also use specialized equipment like telescopes and software programs to track and observe Neptune's movement across the sky.

no, they divide the sky into constellations
by eyes
Astronomers observe the sky from various locations, including ground-based observatories situated in remote areas with minimal light pollution, such as mountaintops or deserts. They also utilize space telescopes, like the Hubble Space Telescope, which orbit above the Earth's atmosphere to avoid atmospheric distortion and pollution. These diverse locations allow astronomers to gather clearer and more detailed data about celestial objects.
