Question

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

Explanation:

GPS is for position - velocity data, MRI is for medical imaging inside the body, and submarine communication is for underwater communication. Radio telescopes are used to capture radio waves from space objects like asteroids.

Answer:

radio telescope, because it captures radio waves from space
