Which of these describes the majority of our space observations humans have utilized over the history of human space exploration?

A) Gamma ray telescope

B) radio wave telescopes

C) ultraviolet telescopes

D) visible light observatories

Gamma Ray telescopes are the one mostly used by humans for majority of space observations.

Answer: Option A

Explanation:

Since the year 1965, Gamma ray telescopes have attained a major area in space research. As gamma rays are emitted by most of the astrophysical particles like novae, black holes, dwarf stars, supernovae, neutron stars, pulsars, so it is easy to find any changes in space. Even highly energetic gamma burst can also be observed by these telescopes.

So, among the other telescopes like radio, ultraviolet, visible light observations, gamma ray telescopes are mostly preferred for space observations. As the other telescopes have low range of observations and they may have losses. But gamma rays does not interact with other particles, there will be less chance of loss of signals for gamma observations.
