It's an accurate image but the colors are off. They are off because we can't see the particular colors that are actually being detected by the
telescope even though those colors are produced by a solid object. The telescope has blocked out colors we can see with filters and is only detecting
colors in part of the light spectrum called the Near Infrared or NIR. This light vibrates at a frequency (color) below what our eyes can detect. For
another example, our eyes can't detect radio waves even though they are the same type of energy as light but vibrating at a much, much lower frequency
than visible light. Therefore a radio receiver converts the radio frequencys to sound frequencies so we can hear them. Anyway, we tune telescopes to
view the NIR light that objects in space emit for a number of reasons. For instance, longer light waves penetrate gas clouds in space better than
visible light so NIR light let's us see what's through obscuring clouds better. Also the sensors that we use in telescopes are more sensitive when we
allow the NIR light into them because it adds it's energy to the visible light being received by the sensor. At the end of the day the image is
accurate and real but the colors have been substituted for colors that the human eye can see.
Hope that helps.
