Is Shapley a cluster of galaxies?
ESA Science & Technology – Shapley Supercluster The supercluster was discovered in the 1930s by American astronomer Harlow Shapley, as a remarkable concentration of galaxies in the Centaurus constellation.
How far away is the Shapley attractor?
650 million light-years away
It appears as a striking overdensity in the distribution of galaxies in the constellation of Centaurus. It is 650 million light-years away (z=0.046)….

What’s the name of our galaxy cluster?
The Milky Way is part of the Local Group galaxy group (which contains more than 54 galaxies), which in turn is part of the Virgo Supercluster, which is part of the Laniakea Supercluster.
What is Shapley famous for?
Harlow Shapley was the first to realize that the Milky Way Galaxy was much larger than previously believed. Using the 60-inch telescope at Mount Wilson, he took photographs and observed globular clusters, which were compact spheres composed of many thousands of stars.
What would the Great Attractor be?
The Great Attractor is thought to be at the gravitational center of the Laniakea supercluster—of which the Milky Way is but one galaxy of 100,000 others. One theory is that it’s a confluence of dark energy. Another is that it might be caused by over-density, an area of dense mass with an intense gravitational pull.
How far is Shapley Supercluster?
652.3 million light yearsShapley Supercluster / Distance to Earth
Is the Great Attractor pulling us in?
Somewhere out there in the most heavily veiled area of space lies a massive gravitational irregularity that has been dubbed the Great Attractor. Over the course of billions of years, it’s been pulling us and all the galaxies near us closer to it.
Are we being pulled towards the Great Attractor?
Not exactly… Our galaxy and other nearby galaxies are being pulled toward a specific region of space. It’s about 150 million light years away, and here is the best part. We’re not exactly sure what it is.
What cluster is Earth in?
Virgo Supercluster
Well, Earth is located in the universe in the Virgo Supercluster of galaxies. A supercluster is a group of galaxies held together by gravity. Within this supercluster we are in a smaller group of galaxies called the Local Group. Earth is in the second largest galaxy of the Local Group – a galaxy called the Milky Way.
Why do we use Shapley value method?
Shapley value helps to determine a payoff for all of the players when each player might have contributed more or less than the others. Shapley value has numerous applications whereby the players could instead be factors needed to achieve the desired outcome or the payoff.
How do we know there is a black hole in the center of our galaxy?
Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas. This chart shows the relative masses of super-dense cosmic objects.
Will the Great Attractor destroy us?
‘Fortunately, the great attractor won’t destroy our galaxy because we’ll never reach it. About 5 billion years ago, dark energy began to dominate our universe.,’ Dr Sutter told MailOnline. ‘We don’t know what dark energy exactly is, but we do know that it’s causing the expansion of our universe to accelerate.
