Physics Galaxy Discussion Questions Solutions Here

The estimated mass of the Milky Way galaxy is approximately 10^11 solar masses (M). However, this value can vary depending on the method used to estimate the mass, and some studies suggest that the mass could be higher, up to 10^12 M.

Galaxy mergers can lead to the formation of a new, more massive galaxy, with a changed structure and composition. The merger can trigger starbursts, and the resulting galaxy may have a different shape, size, and stellar population. physics galaxy discussion questions solutions

Dark matter plays a crucial role in galaxy formation and evolution, as it provides the gravitational scaffolding for normal matter to clump together and form galaxies. Dark matter also helps to regulate the flow of gas and stars within galaxies, influencing the rate of star formation and galaxy growth. The estimated mass of the Milky Way galaxy

How do galaxy mergers affect the structure and composition of the resulting galaxy? The merger can trigger starbursts, and the resulting
