Neptune has been studied using telescopes such as Hubble, ground-based observatories, and space probes like Voyager 2. Scientists also use computer simulations to study Neptune's atmosphere, magnetic field, and internal structure. Additionally, radio telescopes are used to study radio emissions from Neptune.
Blue giant stars were not discovered by one person, as they have been observed and studied by astronomers over time. However, they were first classified and extensively studied by Annie Jump Cannon and Ejnar Hertzsprung in the early 20th century.

Actually this statement is in the present perfect progressive tense, and to change it into passive it could be this way ( English has been being studied.), but as a matter of fact it is no longer be used in this way, as its sound is very unfamiliar, or the present perfect progressive tense is no longer used in the passive , but we can use the present perfect simple tense instead. so the right answer is " English has been studied."

The U.S. Mint did not produce any gold dollars for the bicentennial. There are aftermarket examples of gold plated dollars but they are just regular production coins which have been gold plated. They have no added numismatic value and their actual value is limited to the value of the metals in them .
