Where in the Milky Way will you find most of the globular clusters quizlet?
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 are globular clusters located in our galaxy?
Globular clusters orbit in the halo of our galaxy, centered on the galaxy’s center and expanding above and below the galactic disk. Open star clusters tend to orbit within the disk.
Where can I find globular cluster M13?
It’s found in a star pattern called the Keystone – a lopsided square within the constellation Hercules – between the two brightest stars of northern spring and summer, Vega and Arcturus. At mid-northern latitudes, the M13 cluster can be found in the sky for at least part of the night all year round.
Where are open clusters found in the Milky Way?
disk of the Galaxy
What is the relationship between globular clusters and the Milky Way?
Globular clusters are nearly spherical groups of about 10,000 to 1 million stars. A typical galaxy may contain up to a few hundred globular clusters; our galaxy, the Milky Way, has somewhere between 125 and 200 globular clusters orbiting the galactic center.
What is the closest globular cluster?
M4
How can you tell how old a globular cluster is?
By determining the mass of the main-sequence turnoff stars, we get the age of the cluster. The cluster age equals the main-sequence lifetime of the turnoff stars. This is one of the ways we have studied the age of the Universe and the formation history of the Galaxy.
Are we moving closer to the center of the Milky Way?
Bottom line: A new project to map the Milky Way has shown that Earth is both moving faster and is closer to the supermassive black hole at the center of our galaxy than previously thought. And Earth and our solar system are moving faster – around the center of the galaxy – at 227 km/second, instead of 220 km/second.
Have we found the center of the universe?
There is no centre of the universe! According to the standard theories of cosmology, the universe started with a “Big Bang” about 14 thousand million years ago and has been expanding ever since. Yet there is no centre to the expansion; it is the same everywhere.
What is bigger than the universe?
Cosmos At Least 250x Bigger Than Visible Universe, Say Cosmologists. The universe is much bigger than it looks, according to a study of the latest observations. When we look out into the Universe, the stuff we can see must be close enough for light to have reached us since the Universe began.
What is the most massive thing in the universe?
List of the largest cosmic structures
| Structure name (year discovered) | Maximum dimension (in light-years) | Notes |
|---|---|---|
| Virgo Supercluster | /td> | Part of the Laniakea Supercluster (see above). It also contains the Milky Way Galaxy, which contains the Solar System where the Earth orbits the Sun. Reported for reference |
Which is the biggest thing in the universe?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
What is the first thing in the universe?
The Big Bang is thought to have kick-started the universe about 13.7 billion years ago. At first, the universe was too hot and dense for particles to be stable, but then the first quarks formed, which then grouped together to make protons and neutrons, and eventually the first atoms were created.
What is the most powerful star?
magnetar
