Stars are the sources of light. If they did not emit light, there would be no stars and thus no astronomy.
Astronomy was all done with the naked eye at that time. Perhaps the most notable tool that the Egyptians used was the plumbline, for estabishing a perfect vertical, this enabled the altitude of stars above the horizon to be measured more accurately.
The first measurement tool was likely a simple ruler or measuring stick, used by ancient civilizations such as the Egyptians or Mesopotamians. It was used to measure length or distance for various purposes, including in construction, trade, and astronomy.
Astronomy, yes; mediciline, no.
It means1) "of, pertaining to, or connected with astronomy" (the study of stars)2) "large in number or size"The idiomatic meaning of "huge," "having a high numerical value," or "exorbitant" (as in astronomical prices) came about because of the large numbers that are frequently used in astronomy, for the vast distances in space.
The distance used to measure astronomical distances is called a light-year. It represents the distance that light travels in a vacuum in one year, approximately 5.88 trillion miles or about 9.46 trillion kilometers. Light-years are commonly used in astronomy to express vast distances between stars and galaxies.

Studying light is one part of astronomy. Things like the speed of light, how it travels, the spectrum of light are all things that are used in studying astronomy. Studying light emitted from a star can tell us all sorts of things about it, like how far away it is and how bright it really is.
A unit that is commonly used in astronomy is the light-year - the distance light travels in a year.

Light years are a unit of measurement used in astronomy to indicate the distance that light travels in one year. This distance is about 5.88 trillion miles. Light years are significant in astronomy because they allow scientists to measure vast distances in space, such as the distance between stars, galaxies, and other celestial objects.
A parasec is a length of distance usually used in astronomy that is equal to 3.26163626 light years.
A mirror is the science tool that can be used to reflect light. It is a smooth, shiny surface that reflects light rays in a predictable manner. Mirrors are commonly used in experiments and optical devices to redirect and focus light.

A telescope is a tool that can be used to make faraway objects appear closer. It works by gathering and magnifying light from distant objects, allowing for a clearer and more detailed view. Telescopes are commonly used in astronomy to observe celestial bodies like stars and planets. Additionally, binoculars serve a similar purpose for terrestrial viewing.
The prism does this.
