Astronomers use a telescope to study radiation, at least the electromagnetic kind. But there is a broad range of this radiation that astronomers study. Pull up a chair and let's look a bit further into things.
We often think of the telescope as the primary instrument of the astronomer. But we also usually think of that "big eye" as looking for light sources. That's an optical telescope. Recall that visible light represents only a small portion of what is called the electromagnetic spectrum. (Light is electromagnetic energy.) There are ultraviolet rays, X-rays and gamma rays higher in frequency than visible light. And infrared rays, microwaves and all those radio waves are lower in frequency that the light we see.
Astronomers have to differentiate between telescopes so that it is clear what they are doing with them. That is, they have to know what types or what frequencies of electromagnetic radiation they are working with. Each type has value, and things that cannot be seen with an optical telescope will absolutely astonish an observer who is looking at images in the infrared, ultraviolet or microwave region. Heck, we even put telescopes of different kinds into orbit. Many if not most of those stunning images of stars, nebulae and the like that we see published are actually "enhanced" by combining observations of different types of telescopes to make up the image.
Keep in mind the broad range of energies (frequencies) in the electromagnetic spectrum when thinking about what astromomers are looking at when they peer out into space. That will help you figure out what they are using to look at stuff. There is a lotmore out there than meets the eye. A whole lot more. And we've only just scratched the surface.
Long-wave electromagnetic radiation used in special telescopes includes infrared radiation and submillimeter radiation. These telescopes are designed to detect and study objects that emit or reflect these longer wavelengths of light, allowing astronomers to observe phenomena such as cool stars, cosmic dust, and molecular clouds.
Telescopes are used by astronomers to collect light from celestial objects such as stars, planets, and galaxies. They enable astronomers to study these objects in detail, revealing information about their properties, composition, and motion. Telescopes can also help astronomers in detecting and studying phenomena like supernovae, black holes, and exoplanets.
Some other types of telescopes used by astronomers to observe stars include radio telescopes, which detect radio waves emitted by stars, and space telescopes like the Hubble Space Telescope, which is specifically designed for observations in space without the distortion caused by Earth's atmosphere. Astronomers also use infrared telescopes to study stars emitting infrared radiation, providing valuable insights into their composition and temperature.
The scientific tool based on how atoms absorb and emit electromagnetic radiation is called a spectrophotometer. It measures the absorption and emission of light by atoms or molecules to analyze their properties and concentrations. This tool is widely used in various fields such as chemistry, biochemistry, and physics for qualitative and quantitative analysis.
Ultraviolet telescopes are used to observe celestial objects emitting ultraviolet radiation, which is not visible to the human eye. They provide valuable information about the composition, temperature, and dynamics of stars, galaxies, and other astronomical phenomena that emit UV light. This can help astronomers study the formation of stars, the evolution of galaxies, and the presence of elements in the universe.
