Answer:
The galaxy is moving closer to us
Explanation:
When there is a decrease in the wavelength of light which is being observed then it means that the object and observer are getting closer to each other.
When there is an increase in the wavelength of light which is being observed then it means that the object and observer are getting farther apart.
This phenomenon is called the Doppler effect.
Orange has shorter wavelength than red so the wavelength is getting shorter.

After the explosion of the Toba volcanic the average temperature dropped to about 3 to 3.5 °C, which represents a drastic change for the populations and lasted about six to seven years. This volcanic winter not only affected the local population, but it was a fact with global consequences. This caused the extinction and the diminution of the population to great scales in several Homo species that existed.
