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.

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

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

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

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

"the solar system's largest planet" refers to jupiter and not the jupeter's mass. That shud clear the dicussion between A and B. A is a clear winner

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
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
Invalid modifier (Jupiters mass is the solar system's largest planet? No!) - wrong answer

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
The interplay of tenses in this sentence changes meaning of the original sentence. This sentence tends to imply that the astronomers have already detected gas sphere and are still working in the canary islands.

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
The first independent clause has no verb

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
Same as B


Hmm. A fleeting glance suggests that the underlined part must end with "Jupiter" as the non-underlined part after it tends to modify some planet (in this case, jupiter).

So rule out B/E
A vs C vs D (explained above)

In d, putting comma between astronomers and working makes the meaning of the sentence different from b (without comma)


Between "estimate to be" vs. "estimate to have" because this sentence go with measurement, infinitive is prefer. We cannot say that "gas sphere" is "5 to 15 times" that "estimate to be" say. Another usage, "estimate"can go before "that"

Comma make the part between comma become restrictive. In this sentence, we need non-restrictive adjective phrase. If we put the comma, the sentence become that all the astronomer in the world are those who working at telescopes in the Canary Islands and Spain. We need to say that some of astronomer in unique field work at telescope in the Canary Island and Spain.

Choice A is correct one.

+1 for A.

The problem with B is the phrase "...estimated to be 5 to 15 times Jupiter’s mass" .

"Estimated to be...mass" in option B is wrong.
"Mass" is something that one "has". That is why "have" in A is correct.

"The gas spheres have a mass 5 to 15 times that of Jupiter". This sentence makes sense.

Hence, A is the correct answer.

Is estimated at not the correct Idiom?

"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 --- correct choice. Uses the right idiom- estimated to -

(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 is not the solar system’s largest planet. It is the Jupiter. Wrong modification.

(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 --- when you estimate something, you can’t estimate at something so precisely; 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—the same problem as in C; in addition first of the text is a fragment

(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 is not the solar systems’ largest planet . The same problem as in B
