The age of a galaxy is determined by studying the oldest stars within it using methods like measuring the radioactive decay of elements, analyzing the chemical composition of stars, and calculating the expansion rate of the universe. By combining these techniques, astronomers can estimate the age of galaxies in the universe.

How did Harlow Shapley determine where the center of the galaxy lies?
Harlow Shapley determined the center of the galaxy by studying the distribution and motion of globular clusters. By observing the positions and velocities of these clusters, he discovered that they were not evenly distributed in the sky but rather congregated towards a point in the constellation Sagittarius, indicating the center of the galaxy.

What determines the look back time of an object?
The look back time of an object is determined by how long it takes the light from that object, usually a star or galaxy, to reach an observer here on earth.
How a star dies is determined by its age shape position in its galaxy mass?
A star's death is primarily determined by its mass. Low to medium mass stars, like our Sun, will eventually exhaust their fuel and turn into a red giant before shedding their outer layers to form a planetary nebula and eventually becoming a white dwarf. Higher mass stars can undergo supernova explosions and leave behind neutron stars or black holes. Other factors such as age, shape, and position can influence the details of the death process, but mass is the most critical factor.
Is the color of a star determined by its location in the galaxy?
No. The color is determined by the star's temperature, not location.
Who determined the shape of galaxy?
God. He chose a nice shape, no?
Is a young galaxy an irregular galaxy?
That is unrelated to age. An irregular galaxy is one that has been distored by the gravity of nearby galaxies.
