A macroscope is a tool that scientists use to study things that are too small or too far away to be seen with the naked eye. It can be compared to a microscope, which is a magnifying tool used to look at tiny things up close. The main difference is that a macroscope helps scientists to observe things that are too big or too far away for a microscope to be useful. A macroscope helps scientists get a larger view or a wider perspective of an area or environment. The biggest macroscopes are often giant telescopes that are used to study planets and stars, or even the universe.
