Why do we need to send a satellite (New Horizon) to photograph color pluton when we have telescopes that see galaxies much farther?
The ability to see so far in space is based solely on light. Pluto does not give off light itself and is too distant to reflect visible light from the Sun. When we are looking at distant galaxies through a telescope we are looking at the stars in the galaxy.
The Short Answer
The ability to see so far in space is based solely on light. Pluto does not give off light itself and is too distant to reflect visible light from the Sun. When we are looking at distant galaxies through a telescope we are looking at the stars in the galaxy. We have not yet been able to visually see an exoplanet (planets outside of our solar system). We have however confirmed the existence of exoplanets by [other means](_URL_0_).
