"Estimated at" can be used correctly in other contexts, but for this sentence, what we're estimating is mass, and mass is something that you HAVE, not something that you ARE, and "estimated at" doesn't fully convey this.

It has to be A, since it correctly uses "has" (the noun is "team", not "astronomers"!), uses "estimated to have", and has the most straightforward sentence structure.

Side note: "working at" seems awkward to me (any other opinions?), but it doesn't really change the question, since there are no alternatives to it.

B is incorrect because it says "18 huge gas spheres estimated to be 5 to 15 times Jupiter’s mass" and while something can HAVE mass (the mass of Earth, Earth's mass, Earth has a mass of ___, etc.), it can't BE mass.

Hope that helps!

Is this explanation correct:

Since the sentence should end in Jupiter and nor Jupiter's mass, as the following sentence talks about Jupiter being the largest plant. So,

A- concise and correct
BX- ends in Jupiter's Mass
CX- uses 'having'
D
EX ends in Jupiter's Mass

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
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 (Jupiter's mass, can't be followed by largest planet)
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
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- Problem with the comma
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 (Jupiter's mass, can't be followed by largest planet)

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.

Is estimated at not the correct Idiom?
