Atomic and molecular astrophysics
Atomic astrophysics is concerned with performing
atomic transitions
.
Molecular astrophysics, developed into a rigorous field of investigation by
gigahertz
. This frequency is a thousand times higher than typical FM radio frequencies. At these high frequencies, molecules in the Earth's atmosphere can block transmissions from space, and telescopes must be located in dry (water is an important atmospheric blocker), high sites. Radio telescopes must have very accurate surfaces to produce high fidelity images.
