Concept explainers
The color that represents the brightest radio emission and the color that represents the lowest levels of brightness.
Answer to Problem 1VSC
Solution:
The color that represents the brightest radio emission is white and the color that represents the lowest levels of brightness is black/dark blue.
Explanation of Solution
As the cold, dense molecular clouds are concentrated in a narrow layer near the midplane of the galactic disk, the white color in the middle represents the brightest radio emission.
As we see away from the midplane, there is less concentration of molecular clouds. So, the black/dark blue color represents the lowest levels of brightness.
Conclusion:
The color that represents the brightest radio emission is white and the color that represents the lowest levels of brightness is black/dark blue.
