Why do astronomers also need information provided by gamma rays, x rays, infrared, and radio telescopes? - telescopes information
Optical telescopes reveal the nature of astronomical objects, why have above all the astronomers.

Because we can do a lot more about the objects in the universe with them! The light is only a small portion of the electromagnetic spectrum, so that if we only this spectrum, which use only a very small part of the universe.
Take, for example, Sirius A and B. With Senseta see light with the naked eye, Sirus A much, much brighter opaque than its counterpart. However, if you have an X-ray telescope is Infact Sirius B, is the brightest here, and here we can work that Sirius B is a star much smaller but more compact than Sirius A. That 's a simple example, which other sources of wavelengths are useful. Other examples are black holes (objects that emit gamma radiation prior to entry) and Seyfert (galaxies) the large amounts of radio waves.
I hope that helped!
optical telescopes give us only a small piece of spectrum available.
For example: One of the Keck Telescope is an infrared telescope. Infrared detectors can through interstellar dust and gas in the optical telescopes can not see.
Many of the images you see from NASA and other space agencies have released composite images from several different wavelengths. This is done to correlate the information. It is the object that sends X-rays? Have they emit gamma rays? Is infrared? These are strong indications that the object is or what he does.
