Globular clusters have much higher stellar densities than the local solar neighborhood. Open clusters are only found in the disk of the Milky Way; globular clusters are only found in the halo of the Milky Way .
Where in the Milky Way will you find most of the globular clusters?
Globular star clusters are known to be located mostly in the great spherical halo of the Milky Way . Spiral galaxies like our Milky Way contain stars, gas and dust, mostly organized into a flat disk containing the spiral arms, but with the addition of a more rounded bulge and halo, centered on the galaxy's center.
Where are globular clusters located quizlet?
Globular clusters contain thousands of stars, all closely packed together. They are found mainly in the halo of the galaxy .
What causes our Milky Way to have spiral arms?
Astronomers believe that galaxies have spiral arms because galaxies rotate – or spin around a central axis – and because of something called “density waves .” ... Stars pass through the wave as they orbit the galaxy center. The wave causes the stars to slow slightly and temporarily clump together.
Which component of the Milky Way galaxy contains globular clusters?
5.5 Stellar Halo (Extreme Population II) The stellar halo of the Milky Way includes the system of globular clusters, metal-poor high-velocity stars in the solar neighborhood, and metal-poor high latitude stars. The total mass of the stellar halo is only about 10^9 M_sun.
How many stars are in a globular cluster?
Globular clusters are big. They can reach 300 light-years in diameter and contain 10 million stars .
How many globular clusters are in the Milky Way?
There are about 150 known globular clusters in the Milky Way galaxy, according to Georgia State University's HyperPhysics website. Most are estimated to be at least 10 billion years old, and contain some of the oldest stars in the galaxy.
How are globular clusters distributed in the galaxy quizlet?
how are globular clusters distributed in the galaxy? ... in the spherical halo around the galaxy and in the central bulge . where are molecular clouds in our galaxy located? in the spiral arms and can be used to trace the spiral structure of our galaxy.
Which is the best description of a globular cluster quizlet?
What best describes globular clusters? They contain from hundreds of thousands to millions of stars and have a typical size of about 50 parsecs . A small group of atoms does not collapse into a clump because ________ quickly disperses them. You just studied 16 terms!
How are globular clusters distributed in our Milky Way galaxy quizlet?
How are globular clusters distributed in our Milky Way Galaxy? Mostly in a large spherical halo surrounding the flat disk of the Galaxy . ... Dust in the space between stars builds up over large distances and blocks the light of stars behind the dustier parts of the Milky Way.
Is the Milky Way a 2 arm spiral?
The Milky Way is known to have two main spiral arms, the Perseus arm and the Scutum-Centaurus arm . Our galaxy also possesses two less pronounced arms, or spurs, called the Sagittarius and the Local Arm (which passes close to the sun).
Does the Milky Way have arms?
The Milky Way Galaxy is immense. It is 150,000 light-years in diameter. Our Solar System resides roughly 26,000 light-years away from the Galactic Center. Our Milky Way galaxy has spiral arms , where stars are born from clouds of molecular gas and shine for billions of years.
How do we know what Milky Way looks like?
The clues we have to the shape of the Milky Way are: 1) When you look toward the Galactic Center with your eye, you see a long, thin strip . This suggests a disk seen edge-on, rather than a ellipsoid or another shape. We can also detect the bulge at the center.
What is the relationship between globular clusters and Milky Way?
So the globular clusters (which contain very old stars) reveal a spherical component of the Milky Way , while the open clusters and other young stars and star-forming regions reveal a disk-shaped component of the Milky Way.
What is the meaning of globular cluster?
Globular cluster, a large group of old stars that are closely packed in a symmetrical, somewhat spherical form . Globular clusters, so called because of their roughly spherical appearance, are the largest and most massive star clusters.
Where are open clusters found in the Milky Way?
Open clusters are found in the disk of the Galaxy . They have a range of ages, some as old as, or even older than, our Sun. The youngest open clusters are still associated with the interstellar matter from which they formed.
