by plotting the distribution of open clusters
Harlow Shapley was born on November 2, 1885 and died on October 20, 1972. Harlow Shapley would have been 86 years old at the time of death or 129 years old today.
There are two observable entities at, or near the centre of the Andromeda Galaxy. The dimmer, P2, falls at the true center of the galaxy and contains a 108 solar mass black hole.
25,000 light-years.
no, it revolves around the Center of the MilkyWay Galaxy...
About 25,000 light-years from the center.
Harlow Shapley studied globular clusters and used the position of the clusters to locate the sun in the middle of our galaxy. He found out he was wrong but figured out that the sun was in one of the spiral arms in our galaxy

mabye yes
Shapley
As that's the prevailing view, pretty much everybody except Harlow Shapley, who thought the Milky Way was the major feature of the universe and all the "nebulae" were its satellites. In the "Great Debate" (in the year 1920) between Harlow Shapley and Heber Curtis on this subject, it was Curtis who argued that many of the nebulae were outside our Galaxy. So, the answer you want is probably "Heber Curtis".
As best we can determine, every galaxy has one in its center.
Probably the same as the center of YOUR galaxy.
The center of a spiral galaxy is which color

The average stellar mass x the number of stars ______________________________ We can calculate the mass of the Milky Way by observing the speed at which stars orbit the center, as long as we can determine how far away they are from the center.
A spiral galaxy
I can't determine what you're asking about. Stars do travel; they orbit around the center of the Milky Way Galaxy.
