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.
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 does a galaxy have clusters of?
A galaxy typically has several star clusters.
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.
Does gravitational lensing magnify distant galaxies at distances up to 13 billion light years behind galaxy clusters?
Yes. Lensing magnifies the image of galaxies behind distant galaxy clusters but also greatly distorts the image.
What are galaxy clusters about?
The galaxy clusters are the solar systems orbiting the galaxies.
Why is studying star clusters useful?
Studying star clusters can provide important insights into stellar evolution, the structure of our galaxy, and the formation of stars. Analyzing the properties of stars within clusters allows scientists to better understand their ages, masses, and chemical compositions, which can in turn help refine models of stellar formation and evolution. Additionally, by studying how star clusters are distributed in the galaxy, astronomers can gain valuable information about the history and structure of our Milky Way.
Where in the spiral galaxy you would expect to find globular clusters?
Globular clusters are typically found in the halos of spiral galaxies, rather than in the main disk. They orbit the galaxy at various distances and are often located in the regions surrounding the galactic center. These clusters are ancient collections of stars, and their presence in the halo indicates their formation in the early stages of galaxy evolution.
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 does a galaxy include?
global clusters, open clusters and star clusters. (:
List the structures in order galaxies planets superclusters star clusters galaxy groups planetary systems galaxy clusters?
Planetary systems, star clusters, galaxy groups, galaxies, galaxy clusters, superclusters in order from smallest to largest.
Do galaxies orbit an object?
Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.
