A radio object is something in the Cosmos that emits relatively strong radio waves.
These include pulsars, quasars, and radio galaxies that all emit very intense radio waves.
Weaker objects include more local bodies, such as the Sun, Jupiter, and our own Milky Way galaxies' center.
Others include remnants of supernovae and the cosmic background radiation of the Universe.
The direct object is radio. (You can turn the radio up.)

Optical telescopes rely on light waves being sent from the object being observed. Weather conditions (clouds) can block the light from the object reaching the telescope's lens. Radio telescopes only search for radio-waves being sent from the object under scrutiny - which are not (as a rule) affected by weather conditions on earth.

Radio waves hit all obstacles the same, but the waves will differ in the distance of the wave and/or the object from the transmitter.
Radar locates objects with radio waves.
