Reber mapped these signals from the sky and shared his findings. Astronomers followed up with new investigations and soon began reporting more signals. Over time, with better radio telescopes, they found that some radio sources appeared as paired patches, one on either side of a tiny dot. They called these sources "radio galaxies." They also discovered other, more starlike sources—intense dots of radio energy without patches. How strange. 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?The excerpt makes a connection between Reber’s discoveries and the discovery of radio galaxies by later astronomers.
The excerpt makes a connection between the discovery of radio galaxies and the discovery of black holes.
The excerpt makes a connection between the invention of radio telescopes and the discovery of black holes.

Option 3 is correct.
The excerpt makes a connection between the discovery of radio galaxies and the discovery of quasars.
Explanation:
- It is clearly mentioned in the given excerpt that the astronomers found our radio galaxies.
- Later on, they also discovered intense dots of radio energy or star-like sources called quasars.
- So the excerpt has the connection between radio galaxies and quasars.
