How did Harlow Shapley make the discovery?
Harlow Shapley made his discovery by studying the distribution of globular clusters in the Milky Way galaxy. By mapping their positions and recognizing that they were concentrated in a region around a central point, he inferred that the Sun was not at the center of the galaxy but rather located in one of its spiral arms. Shapley's work involved analyzing the brightness and distances of these clusters, leading to his conclusion about the galaxy's structure and the Sun's position within it. This significantly advanced our understanding of the Milky Way's size and shape.
What distinguishes a core-halo radio galaxy from a lobe radio galaxy?
Yes
What active galaxy is sending out radio waves?
That's basically the definition of an active galaxy, so I would say, all of them.
What is a radio galaxy?
A radio galaxy is anactive galaxy that is very luminous at radio wavelengths (between 10 MHz and 100 GHz). The radio emission is due to the "synchrotron process" which is caused by the acceleration of charged particles, near the speed of light) through magnetic fields.
What is the galaxy called that sends radio waves?
Quasars
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.
How did shapely and oort say your galaxy compares to most others?
Shapley discovered that the Milky Way is not at the center of the universe, but rather on its outer edge. Oort determined that the galaxy is rotating and that the Sun is located about halfway between the center and the edge.
How does the Milky Way galaxy compare to most others according to Shapely and Oort?
It is fairly typical
What did Harlow Shapley discover?
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
Which objects contain super massive black holes?
As best we can determine, every galaxy has one in its center.

What is the center of your galaxy named?
Probably the same as the center of YOUR galaxy.
What color is the center of the spiral galaxy?
The center of a spiral galaxy is which color
Why was Harlow Shaply famous?
Harlow Shapley was a famous astronomer known for his significant contributions to the field of astronomy. He measured the size of the Milky Way galaxy and correctly positioned the Sun within it. Additionally, he played a key role in the Great Debate of 1920 where he argued in favor of a universe where galaxies were not part of the Milky Way.
Why didn't astronomers before shapely realize how large the galaxy is?
Before Harlow Shapley’s work in the early 20th century, astronomers underestimated the size of the Milky Way galaxy due to limited observational data and a lack of understanding of its structure. They primarily viewed the galaxy as a collection of stars within a relatively small area, influenced by the bright band of the Milky Way visible from Earth. Shapley's research, particularly through the study of globular clusters and their distances, revealed the true scale of the galaxy, demonstrating that it was much larger than previously thought. This shift in perspective ultimately led to a more accurate understanding of our galaxy's vastness.
What color is the center of a spiral galaxy?
The center of a spiral galaxy is which color
What is at the center of every galaxy?
At the center of every galaxy is a supermassive black hole.
