Detailed explanation-1: -What Makes Hubble Different From Telescopes on Earth? Earth’s atmosphere alters and blocks the light that comes from space. Hubble orbits above Earth’s atmosphere, which gives it a better view of the universe than telescopes have at ground level.
Detailed explanation-2: -Hubble images are 5 to 20 times sharper than those obtained from the ground, in effect bringing the universe that much “closer” (Figure 3.2). Image sharpness and the extremely dark sky help Hubble to see objects 10 times fainter than those that can be observed with even the largest ground-based telescopes.
Detailed explanation-3: -A) in orbit, it can operate close to its diffraction limit at visible wavelengths. 2) The Hubble Space Telescope gives us its best resolution with X-rays.
Detailed explanation-4: -Because it is above the Earth’s atmosphere. The atmosphere disturbs the starlight (a bit like looking through water) and blurs the images. So Hubble’s images are much sharper than those from other telescopes.
