Astronomers now have various types of telescopes from which to choose in order to study celestial objects like planets, stars, galaxies, and even the Sun. The type of telescope an astronomer uses depends on many factors, one being the type of information that the astronomer wishes to gather about his or her subject of study. As you can see with the two images below, different telescopes provide different types of images. These images of the Whirlpool Galaxy were taken by separate observatories, which use high-powered telescopes for astronomical research.
