The top panorama shows our view of the Milky Way in all directions as it appears in visible light. The bottom panorama shows the same view, but in a different wavelength of light. What wavelength band are we seeing in the bottom photo, and how do you know?
A) infrared light, because the dust that appears dark in the visible light photo glows in infrared light B) x-ray light, because only x-rays allow us to see through the disk of our galaxy C) radio waves, because clouds of gas in the disk of our galaxy appear pinkish when we look at them with radio telescopes D) infrared light, because clouds of gas and dust appear pinkish when we look at them with infrared telescopes
What evidence from the careful examination of impact craters provides evidence that Mars had surface water long ago?
