Which gives the Hubble Space Telescope an advantage over telescopes on Earth?
A
its location
B
its being a natural satellite
C
its low cost of construction
D
its ease of accessibility for repairs
Explanation: 

Detailed explanation-1: -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. Also, Hubble is able to see in ultraviolet wavelengths that are blocked by the Earth’s atmosphere.

Detailed explanation-2: -The Hubble telescope provides four key advantages over most other optical astronomical facilities: unprecedented angular resolution over a large field, spectral coverage from the near infrared to the far ultraviolet, an extremely dark sky, and highly stable images that enable precision photometry.

Detailed explanation-3: -Though Hubble’s mirror is much smaller than those found in the largest ground-based observatories, the telescope’s unique position above Earth’s atmosphere gives it incredible clarity. As the telescope orbits Earth, its mirror gathers light from the cosmos, collecting images and data.

Detailed explanation-4: -Hubble isn’t that far away, but its location above the murky atmosphere allows the telescope to get a clear view of the universe. Earth’s atmosphere distorts and blurs light, and absorbs certain wavelengths of the electromagnetic spectrum.
