Human error is reduced by the use of the Hubble telescope.

Detailed explanation-1: -Since 1990, the Hubble Space Telescope has been orbiting Earth and sending back images of space for astronomers to view and interpret. What benefit is there to a telescope that orbits Earth? Earthbased telescopes have a greater range of light detection.
Detailed explanation-2: -Earth’s atmosphere changes and blocks some of the light that comes from space. Hubble flies around, or orbits, high above Earth and its atmosphere. So, Hubble can see space better than telescopes on Earth can.
Detailed explanation-3: -Hubble also provided conclusive evidence for the existence of Supermassive Black Holes in the centres of galaxies by observing the galaxy M87. 1995 | Hubble took the famous photo of the Eagle Nebula which was later named ‘pillars of creation’.
Detailed explanation-4: -Similarly, Hubble has two types of antennas to send and receive signals: high-gain antennas (HGAs) and low-gain antennas (LGAs). The LGAs are small, stationary, spiral cone antennas that can send and receive signals in every direction.
