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? GPS, because it uses satellites that provide position and velocity data
radio telescope, because it captures radio waves from space
MRI, because it uses magnets to produce a picture
submarine communication, because it uses LF radio waves

radio telescope, because it captures radio waves from space

Explanation:

The technology the scientists used to capture the image is likely to be a radio telescope. This telescope is able to produce images from electrical signals transmitted by the radio waves the trail of the asteroid generates.
