D-The excerpt makes a connection between the discovery radio galaxies and the discovery of quasars. C-The excerpt makes a connection between the invention of radio telescopes and the discovery of black holes. B-The excerpt makes a connection between the discovery of radio galaxies and the discovery of black holes. What could these quasars (short for "quasi-stellar radio sources") be? Were they related to the radio galaxies? Which statement best describes the connection made in the excerpt? A-The excerpt makes a connection between Reber's discoveries and the discovery of radio galaxies by later astronomers. They called these sources "radio galaxies." They also discovered other, more starlike sources-intense dots of radio energy without patches. There’s also a super natural, sci-fi element to the film as black holes are typically found in space. This is shown by the characters facial expressions and movements, these make up for the lack of dialogue during the film. Over time, with better radio telescopes, they found that some radio sources appeared as paired patches, one on either side of a tiny dot. It is evident from this film that comedy is the focal point to the storyline.
Astronomers followed up with new investigations and soon began reporting more signals. Reber mapped these signals from the sky and shared his findings.
