the stars have lived long enough to move there.

In general, older stars have lower ___ than younger stars. Astronomers just determined the exact weight of the Milky Way galaxy for the first time!

The bar might be as long as 27,000 light-years long. Middle School. Physics. in general, older stars have lower____-than younger stars. Rank in order of age, globular clusters with main sequence turnoffs at the following temperatures: 10,000K, 3,000K, and 6,000K. c. Find the distance to the center of the distribution of globular clusters, which is the distance to the center of the Milky Way. And it’s weight 1.5 trillion solar masses! The distance to one prominent globular cluster, M13, had been determined.

Match. In this figure, the X and Y axes are in units of distances in kiloparsecs (1 kiloparsec = 1,000 parsecs). In this case, the objects in question are globular clusters – ancient bunches of stars that orbit the Milky Way. By combining Gaia’s measurements of 34 globular clusters with measurements of 12 more distant clusters from Hubble, we could pin down the Milky Way’s mass in a way … the size of the Milky Way is determined from studying_____in global cluster. Some recent evidence suggests the bulge might not be spherical, but is instead shaped like a bar. Rank, in increasing order of age, globular clusters with main- sequence turnoffs at the following temperatures. Ask your question. ASTR 264 Chapter 21. The size of the Milky Way is determined from studying _________ stars in globular clusters. Test. standard candles .
They are sprinkled around the center of the galaxy like seeds in a pumpkin. note that the sun is traveling approximately 220 km/s and is 8 kpc from the center of the milky way 230 million years studying standard candles in globular clusters offered the first conclusive proof that our galaxy was much ___ than originally believed a. Cepheid variable b. blue supergiant c. RR Lyrae d. Sun-like Flashcards. 5) Find the distance to the center of the globular clusters, which is the distance to the center of the Milky Way. Older stars are found farther from the midplane of a galactic disk because.

The size of the Milky Way is determined from studying ___ in globular clusters. Created by. e. Find the period of the variable stars. 10,000, 6,000, 3,000.

He arrived at his size determination by establishing the spatial distribution of globular clusters. RR Lyrae. Gravity. 1. Find an answer to your question The size of the Milky Way is determined from studying_____ in globular clusters A)LL Lyrae Variable Stars B) velocities C) sta… 1. abundance of heavy elements. Join now. Of about 150-180 globular clusters known in the Milky Way, about a quarter are located within the Galaxy’s greatly obscured and tightly packed central bulge region. Shapley based his ideas on the size of the Milky Way on observations of globular star clusters. Called globular clusters, these ancient bundles of stars date back to the birth of our Milky Way galaxy, 13 or so billion years ago. The hatched region represents the plane of the Milky Way (that is, roughly the part of the sky where the Milky Way is visible to the eye), and the X located at (0,0) marks the location of the Sun in the plane of the Milky Way. Milky Way Galaxy - Milky Way Galaxy - The structure and dynamics of the Milky Way Galaxy: The first reliable measurement of the size of the Galaxy was made in 1917 by American astronomer Harlow Shapley. Log in. 5 points abrownthegoat53 Asked 05/01/2020. d. Find the direction to the center of the distribution of the globular clusters. Astronomers use clusters as tools for studying the Milky Way's age and formation.
