IMO A

As only the option A has the correct idiom of "Estimated to"

What is OA?

B and E can be eliminated because the sentence cannot end with Jupiter's mass, the solar system's largest planet. as the phrase 'the solar system's largest planet' is talking about Jupter and not it's mass.

D can be eliminated because the resultant sentence after removing the phrase-between-the-commas 'astronomers[/color]and has detected' doesn't make sense.

C can be eliminated as the sentence is incomplete. The sentence can be compressed.
A team, having detected X.
A team, having detected X is now in the quest of Y. can be one of the complete constructions.

So IMO A
