A. Look at the way the original sentence ends ... "the solar system's largest planet". This only make sense if it was modifying Jupiter, not Jupiter mass, or anything else.

C.) astronomers is working at telescopes in the Canary Islands and Spain, having detected at least 18 huge gas sphere that are estimated at 5 to 15 times the mass of Jupiter(estimated at is wrong ,also awkward construction)

An international team of astronomers working at telescopes in the Canary islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter, the solar system's largest planet.

Three very easy decision points here
1) Idiom :- estimated at is wrong ; estimated to /to be is correct
2) Subject Verb agreement :- "Team" is singular therefore singular verb should be used.
3) Modifier - "the solar system's largest planet" should modify JUPITER and not Jupiter's mass because Jupiter's mass cannot be a planet.

A. astronomers working at telescopes in the Canary islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter, the solar system's largest planet.
CORRECT

B. astronomers working at telescopes in the Canary islands and Spain has detected at least 18 huge gas spheres estimated to be 5 to 15 times Jupiter's mass
INCORRECT:- jupiter's mass cannot be the largest planet ; Jupiter is the largest planet.

C. astronomers is working at telescopes in the Canary islands and Spain, having detected at least 18 huge gas spheres that are estimated at 5 to 15 times the mass of Jupiter
WRONG:- having is incorrect tense. Estimated at is wrong idiom

D. astronomers, working at telescopes in the Canary islands and Spain, and has detected at least 18 huge gas spheres estimated at 5 to 15 times the mass of Jupiter
WRONG:- Estimated at is wrong idiom

E. astronomers, working at telescopes in the Canary islands and Spain, has detected at least 18 huge gas spheres they have estimated to be 5 to 15 times Jupiter's mass
INCORRECT:- Team is singular and the subject of the sentence. therefore "they" is wrong pronoun and is used incorrectly "have" is incorrect; Jupiter's mass is incorrect because mass cannot the biggest planet.
