You must place some photosensitive material or device in a place where the light of
the universe can fall directly on it. Suitable materials and devices include photographic
film, the human eye, a glass plate coated with collodion, a stiff paper saturated with
silver nitrate, the Charge Coupled Device (CCD), and other photosensitive electronic
devices such as the vidicon, image orthicon, etc.

Roughly 14 billion light years.
This question makes no sense.
The universe is dark because in the vacuum of space, there is nothing for light to bounce off of and become visible.
The visible light spectrum is important for capturing clear pictures of the universe because it allows us to see the colors and details of celestial objects. By using visible light, astronomers can study the composition, temperature, and movement of stars, galaxies, and other cosmic phenomena. This helps us better understand the universe and its many mysteries.
Scientists can utilize the technique of observing very distant objects, such as galaxies and stars, to gain insights into the universe by studying the light emitted from these objects. By analyzing the light, scientists can learn about the composition, age, and movement of these objects, providing valuable information about the history and evolution of the universe.
The Hubble Space Telescope is capable of observing infrared and ultraviolet radiation, as well as visible light. Equipped with specialized instruments, it can capture a wide range of wavelengths, enabling detailed studies of celestial objects and phenomena. This versatility allows astronomers to gather comprehensive data about the universe, including the formation of stars and galaxies.
A visible object that is not a light source is any other object in the universe. Objects that are not light sources reflect light and are thus made to be visible.Examples include:planetspeoplethe mooncarsdogsflowersbooksrocks, either in daylight, or else illuminated by a flashlighta light bulb or LED with the power switched off
No. There is only a Small Part of the Electomagnetic (light) spectrum called visible light. Inside the "visible light" section are the colors of the rainbow, which are the only colors we can see through the naked eye. we cannot normally see Infrared light or UV rays.

Scientists can utilize the technique of observing very distant objects, such as galaxies and stars, to gain insights and knowledge about the universe by studying the light emitted from these objects. By analyzing the light's properties, such as its spectrum and intensity, scientists can learn about the composition, temperature, and movement of these distant objects. This information helps scientists understand the evolution of the universe, the formation of galaxies, and the behavior of celestial bodies.
The closest galaxy which can be seen by the "naked eye" (blushing) is the Andromeda Galaxy which is 2,400,000 light years from earth. We can't see other galaxies because of the extreme distance between Earth and the galaxies.
