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.
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.
What is orbit of the sun?
The sun is in an enormous orbit around the center of the Milky Way galaxy. It is estimated that it takes between 225 and 250 million years for the sun to make one orbit, called a galactic year. We are traveling around the center of the galaxy at a rate of about 220 km/second, which is .073% of the speed of light.
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

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".
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
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.
What is located in the center of every galaxy?
At the center of every galaxy is a supermassive black hole.
