Astronomers use filters when observing and imaging distant objects in space. These filters can be in any color of visible light as well as light that is invisible to human eyes. Each color of light can provide important information about the object that could not be seen otherwise.
Crab Nebula
Radio
Infrared
Visibile light
Ultra violet
X-rays
Gamma rays
The image above shows the Crab Nebula in several different wavelengths. The Crab Nebula is an example of what happens when a very large
star explodes. Astronomers study events like these in as many different wavelengths of light as possible. Based on the image above, why do
astronomers do this? Support your reasoning with three examples from the image above.
