How big is a globular cluster?
A globular cluster is a group of thousands of stars. As the density decreases from the centre, all clusters are measured until the luminosity has decreased by one half - a half radii. So, most globular clusters have a half light radius of around 32 light years.
What is a galaxy and which do you live in?
.A galaxy is, by definition, any large collection of stars that can be recognized as a distinct physical entity. In terms of the number of stars, a small 'dwarf irregular' galaxy like the Small Magellanic Cloud, has about one billion stars in it, but there are even smaller systems that are recognized as galaxies such as the Leo I and II dwarf galaxies with about 1 million stars in them, and the Draco System with a few hundred thousand stars in it. The largest star cluster, a globular cluster called Messier 15 has about 6 million stars, so we see that for small galaxies, there is a blurring together of what we mean by a galaxy and a large star cluster. In addition to their mass and numbers of stars, a galaxy is a collection of stars and gas which move through the universe independently of the Milky Way. Globular clusters are roundish swarms of stars that orbit the Milky Way, while the Leo and Draco Systems seem to be independent collections of stars.And we live in the milky way galaxy By:Cierra Currier
Why are stars distant from one another?
Actually the typical distances between stars vary a lot. Inside a globular cluster, you can have a million stars or so, which are much closer together than in our region.If you ask "Why are they distant from one another in our region of the galaxy", I would say that that can POSSIBLY be answered by the anthropic principle: if stars are much closer together, the conditions MIGHT be catastrophic, and make it difficult for life to survive.
What is a globular cluster?
A globular cluster is a dense group of old stars within a galaxy that have formed a gravity bound spherical shape. They are composed of hundreds of thousands of stars that orbit the center of the galaxy together as a unit. We we don't know a lot about them. There are between one and two hundred globular clusters in the Milky Way, and thousands in very large galaxies, all hanging out around the galactic core. Wikipedia has more information, and a link posted below will take the curious reader over there. Why not drop by and look at the picture of Messier 80 that was put up by our friends?
Are there Star Clusters in your Solar System?
No, a star cluster would be a group of stars; our solar system has only one star in it - the sun, with planets in orbit around it. A star cluster, by contrast, is a much larger structure - a group of from hundreds up to hundreds of thousands of stars (globular clusters can have millions of stars) bound together by gravity. It might be better to say there are star clusters inside our galaxy, the Milky Way.
What is bigger than a galaxy cluster?
The visible universe. I'm a bit of a space buff and to my knowledge there aren't any celestial structures that are larger than a galaxy cluster. The only one I've come upon is the visible universe itself. I could be wrong about that but then again, I could be right. That tends to be how celestial questions like that one go. Hope this helps. Answer 2: Galaxy clusters are clusters of galaxies and therefore larger than individual galaxies. Superclusters are clusters of galaxy clusters and so are larger then galaxy clusters. Filaments are collections of superclusters and are the largest known structures in the universe.
If a cluster of stars faces one direction at 900 pm in one location in the sky how can that same cluster stars be in the same location at 400 in the morning but pointing in the opposite direction?
It cannot be the same cluster due to the rotation of the earth
Is the Coma cluster the nearest cluster?
The Coma cluster is one of the nearest clusters but it is not the nearest. At a mean distance of about 321 million light years the Virgo Cluster is closer at a mean distance of only 59 million light years.
Which discovered galaxy has one of the oldest stars?
The Virgo Cluster. Possible.
Can you see a globular clustar with the naked eye?
Yes. The largest of the globular star clusters, and one of the nearest to the Earth, is Omega Centauri, some 17,000 light years away. Unfortunately, it can only be seen from the Southern Hemisphere. However, M13 (Messier Object 13), the Great Cluster in Hercules, can be seen from the Northern Hemisphere. It contains over 300,000 stars, and its total luminosity is 300 thousand times that of the Sun.
If all the main sequence stars of a star cluster are typically only one hundredth as bright as their main sequence counterparts in the Hyades Cluster than the cluster's distance?
10 times as far as the Hyades's distance.
What is the name of the cluster that planet earth is in?
Planet earth is not in any of the approximately 150 globular clusters which are known to exist in our galaxy, the Milky Way. Our solar system is on one of the spiral arms of the Milky Way.
