The most likely mechanism for the many double radio sources that are now detected in distant space is:
A)two oppositely directed jets of matter, ejected from a small source in the center of a galaxy.
B)two pulsars on opposite sides of a quasar.
C)two black holes on either side of a small galactic nucleus.
D)two radio stars in the spiral arms of a galaxy, symmetrically placed around the galactic nucleus.

Question

Quizplus · Accepted Answer

Double radio sources are typically observed as two oppositely directed jets of matter, ejected from a small source in the center of a galaxy. This is seen in active galactic nuclei and quasars, where jets of matter are propelled away from the supermassive black hole at the center of the galaxy. The jets emit synchrotron radiation, which is what allows them to be detected as radio sources. The other options presented (B, C, and D) do not accurately describe the mechanism behind double radio sources.
