Question

Which of the following is the least likely reason that astronomers consider supernova 1987A so important?

Group of answer choices

The event confirmed theoretical predictions that much of the energy of a supernova explosion is emitted in the form of neutrinos.

Supernova 1987A was the first observable supernova in the Milky Way since the invention of the telescope.

Because supernova 1987A was relatively close and very little dust intervenes between us and the Large Magellanic Cloud, from which the supernova originated, astronomers were able to figure out its total energy output with pretty good accuracy.

The neutrinos preceded the light because they escaped during the collapse, whereas the first light of the explosion was emitted only after the supernova shock had plowed through the body of the star to the surface.

Supernova 1987A represented the first time astronomers had observed a star and knew its basic properties before it exploded.
