Question

What do scientists use to look at astronomical bodies?
a. optical telescopes
b. radio telescopes
c. gamma telescopes
d. microscopes

Answer 1

A whole range of instruments, but telescopes for most work. Most large telescopes are reflectors simply because large glass lenses are very difficult to make. Most modern research optical telescopes are Ritchey-Chrétien but that design is not used exclusively. Radio telescopes are generally simple parabolic dishes.
