In 2010, scientists obtained an image of an asteroid that was dangerously close to Earth. Which technology did the scientists likely use to capture the image?

A radio telescope detects radio waves coming from objects in space, so it is the technology most likely used to obtain an image of an asteroid. GPS provides location and velocity data, while MRI creates images of the body using magnetic fields. Submarine communication is used to communicate underwater, not to image asteroids.
