Answer 2

They don't study the wavelengths of the electromagnetic spectrum. They study objects

that they can't touch by means of the electromagnetic radiation we receive from them at

all possible wavelengths.

The reason is that different objects shine in different electromagnetic wavelengths.

Examples:

-- You can't locate a flashlight with a radio receiver, but you can with your eyes.

-- You can't locate a radio transmitting tower in the dark with your eyes,

but you can with radio receiver.

-- You can't heat leftover meatloaf with a cellphone or an X-ray machine,

but you can do it in seconds with a magnetron tuned to 2.46 GHz.

Answer 3

Conventional telescopes see in visible light, and they can tell us much. But there are pictures taken of some nebulae and galaxies that appear completely different in visible light, infrared, ultraviolet, and x-ray. All the same object, very different pictures. Each type of picture tells astronomers something about that object that the others can't.

Answer 4

These images show important data from visibe light does not show.

Answer 5

Different parts of the electromagnetic spectrum give different types of information.

Answer 6

because they have to
