The center of the galaxy is filled with low-density hydrogen gas that scatters light rays. An astronomer wants to take a picture of the center of the galaxy. Will the view be better using ultraviolet light, visible light, or infrared light? Explain.

The center of the galaxy is filled with low-density hydrogen gas that scatters light rays

1.) Astronomers use detectors of radio, infrared, optical, ultraviolet, X-ray and gamma-ray light to create images of stars and galaxies and other cosmic objects.

2.) An image is just a way for scientists to plot or draw light. Most images show the brightness of an object in the spatial domain, how many photons are coming from a specific location in space. Three properties of an image – size, brightness, and resolution – are the most important properties of an image to a scientist. From size, we learn about astronomical scales, like how big the Moon is.

3.) From brightness, we learn the amount of energy that an object is producing, and then we may be able to figure out how it is producing that energy. The ability of a detector to tell one location from a nearby location is called spatial resolution. Higher resolution lets us know things like whether or not a planet has rings or if there are two stars close to each other, versus one star by itself.

4.) Looking at images of the same object made with different parts of the electromagnetic spectrum is a very important tool for scientists. Each different wavelength of light tells astronomers something unique about that object. By studying all different wavelengths and creating models that explain everything those images show, astronomers can see the the big picture of what is really going on with that object.

Since, scattering $\infty \frac{I}{\lambda }$infrared light reduces the impact of scattering by hydrogen gas.

So, the answer is Infrared light.
