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

Answer 2

radio telescope, because it captures radio waves from space

Step-by-step 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.

• Telescope are used to study very far and distant bodies.
• So, due to their special design, it is the best instrument to use for this kind of study.
• The radio telescope picks radio waves produced from astronomical bodies in space.
