the light rays that are 'bent'[refracted] as they pass through a prism, and then focused upon the receiving 'tray' that contains the film that is processed to form Spectrographs.
Spectrographs are of two types: emission - spectral lines that result from the emission of photons at absolutely specific spectral lines [wavelengths], and - absorption spectral lines that are missing due to the absorbent nature of the interstellar gas & matter clouds that the Source Light passes through.
Constellations is the term used to describe patterns or pictures formed by stars in the sky. The patterns are traditionally named after mythological figures, animals, or objects. Astronomers use constellations as a way to organize and identify specific regions of the night sky.
Early astronomers believed that the dark areas on the moon, known as maria, were vast seas or large bodies of water. They referred to them as "maria," which is Latin for "seas." This misconception arose because the smooth, dark plains appeared similar to water bodies seen on Earth, leading to the assumption that they were filled with liquid. It wasn't until later observations revealed their true nature as basaltic plains formed by ancient volcanic activity.
No. Ancient peoples attributed patterns to the stars.
Becuase nebulae tell us how stars get formed so the composition, density and size of a nebulae cloud says a lot about its age, likelihood of stars forming and the type of stars that might form.
This type of moon is known as a "moonlet" or a "rogue moon." These moons likely formed separately from planets and now travel through space on their own. Rogue moons can be captured by the gravity of larger celestial bodies, such as planets or stars.

By studying rocks from Earth, from the Moon and meteorites it is believed that the age of the Solar System is approximately 4.6 billion years old.

Dark cloud constellations play a significant role in astronomy as they are regions in space where new stars and planets are formed. By studying these dark clouds, astronomers can gain insights into the processes of star formation and the evolution of galaxies. This contributes to our understanding of the universe by providing valuable information about how celestial bodies are created and how they interact within the vast cosmos.
You can notice sandbanks along many high tide bodies of water. These are formations that feature long wavelike patterns in the sand. Sandbanks are formed when sediments are deposited by waves and tides.

Cosmic Background Radiation
Astronomers believe that the solar system formed from a giant rotating cloud of gas and dust called the solar nebula. As the cloud collapsed under its own gravity, it began to spin faster and eventually formed a flat, rotating disk. The Sun formed at the center, while the planets and other objects in the solar system accreted from the material in the disk.
