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.
Who discovered that our sun's was not at the centre of the milky way?
The realization that the Sun is not at the center of the Milky Way galaxy was largely attributed to the work of astronomers in the early 20th century, particularly Harlow Shapley. In the 1910s, Shapley conducted studies of globular clusters and their distances, leading him to conclude that the Sun is located about 26,000 light-years from the galactic center, rather than at its core. This work fundamentally changed our understanding of the Milky Way's structure and our place within it.
What is the distance from Earth to the center of the galaxy?
The distance from Earth to the center of the Milky Way galaxy is approximately 25,000 light-years. The center of our galaxy is home to a supermassive black hole known as Sagittarius A*.
What is at the center of the andromeda galaxy?
At the center of the Andromeda Galaxy is a supermassive black hole known as "Andromeda Galaxy's Center" or M31*. This black hole has a mass equivalent to around 140 million suns and plays a crucial role in shaping the dynamics of the galaxy itself.
Where is your solar system located in your galaxy?
About 25,000 light-years from the center.
How did Harlow Shapely determine where the center of the galaxy lies?
Harlow Shapley determined the center of the Milky Way galaxy by studying the distribution of globular clusters, which are dense groups of stars orbiting the galaxy. He mapped their positions and distances, finding that they were concentrated in a specific region of the sky, which he identified as the galactic center. By analyzing the clusters' distances using variable stars known as Cepheid variables, Shapley concluded that the center of the galaxy is located in the direction of the Sagittarius constellation, specifically around the area of the supermassive black hole known as Sagittarius A*.
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
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.

Did Shapley used the distribution of globular clusters in the galaxy to determine that the Sun was not at the center of the Milky Way?
Yes, Shapley used the distribution of globular clusters in the galaxy to show that the center of the Milky Way was located much farther away than previously thought. By studying the positions and distances of these clusters, he was able to demonstrate that the Sun was not at the center of the galaxy.
Who was the first astronomer to get a reasonable idea of the size and shape of the galaxy?
The first astronomer to propose a reasonable idea of the size and shape of the galaxy was Harlow Shapley in the early 20th century. He used the variable stars known as Cepheid variables to estimate the size of the Milky Way and its position within it. His work helped establish the notion of the galaxy as a vast, spiral-shaped structure.

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.
Which astronomer argued that the milky way is not overwhelmingly huge and that the nebulas are star systems like our own and are immensely distant from it?
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".
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.
Who won the shapley Curtis debate?
The Shapley-Curtis debate, held in 1920, was a significant discussion in the field of astronomy regarding the nature of spiral nebulae. Harlow Shapley defended the idea that spiral nebulae are part of our own Milky Way galaxy, while Heber Curtis argued that they are separate galaxies. Ultimately, while there was no formal winner, Curtis's view was later validated as more evidence emerged supporting the existence of galaxies beyond the Milky Way. The debate highlighted the expanding understanding of the universe in the early 20th century.
Which objects contain super massive black holes?
As best we can determine, every galaxy has one in its center.
