Which is an advantage of using space observatories for space exploration?

The advantage is to avoid the effects of light pollution.

Explanation:

There are several reasons why space observation is desirable in order to avoid problems that terrestrial observatories have. An example of this is that the space observatory does not suffer from the interference of city lights, avoiding light pollution. In addition, thermal turbulence (present in the atmosphere) also does not alter the telescope image.  The terrestrial atmosphere, having a spherical shape, acts as a lens that distorts images (a fact known as optical aberration), so the resolution of terrestrial images has a significant reduction. The atmosphere of our planet also absorbs an important portion of the electromagnetic spectrum (infrared and ultraviolet rays, for example), so some observations are virtually impossible to make.
