The picture below shows a scan of a nebula. There are two images. One image was created using visible light and the other using infrared light. Notice the two arrows point to two celestial objects in the infrared image. These two celestial objects are believed to be newly developed stars.

Which of the following reason are the two celestial objects visible only in the infrared image?

• The infrared image detects brighter objects.

• The visible light image detects brighter objects.

• The two celestial objects give off more infrared light than visible light.

• The two celestial objects give off more visible light than infrared light.
