This is a collection of real photos of the galaxies that make up our Local Supercluster. They’ve been shrunk down (albeit not to scale) and roughly positioned in relation to each other.
About three-quarters of all galaxies are found in clusters. Many tiny clusters of galaxies, like as the Local Group, are seen in close proximity. The Virgo Cluster, which spans 2000 galaxies, is 65 million light years away. The Local Supercluster is named for the proximity of 50 neighboring tiny groups of galaxies to the Virgo cluster, which suggests that they all form a vast flattened cluster of clusters.
The Local Supercluster is frequently referred to as the Virgo Supercluster since it is centered around the Virgo Cluster of galaxies.
Its equatorial plane is nearly parallel to our own Galactic plane.
With a diameter of nearly 100 million light years, our Supercluster has a combined mass of about 1015 times that of the Sun.
The Local Group, which is located on one of the Local Supercluster’s edges, appears to be rotating around its center at a speed of about 400 kilometers per second.

Is the Virgo Supercluster more massive than the entire universe?
It’s time to broaden your horizons and study the Universe’s greatest structures: superclusters, which are huge groups of galaxies. Nothing in the Universe is bigger than this. The Virgo Supercluster is the supercluster in which we reside. It’s a massive grouping of over a million galaxies that stretches across a 110 million light-year-wide region of space.
Our Sun is one of the Milky Way’s members, and the Milky Way is part of the Local Group, a collection of galaxies. The Milky Way, Andromeda, and the Triangulum Galaxy are all huge spiral galaxies, with a few hundred dwarf galaxies thrown in for good measure. The Virgo Cluster has several members, including the Local Group. This galaxy cluster spans 15 million light-years and contains 1200-2000 galaxies. The Virgo Cluster is thus merely one of the Virgo Supercluster’s clusters.
Although astronomers realized we were among a supercluster of galaxies as early as the 1950s, it wasn’t until the 1970s that they mapped out the Virgo Supercluster’s shape, which is similar to our own galaxy. Our Virgo Cluster is a branch of the Virgo Supercluster.
Is the Milky Way or the Virgo Supercluster bigger?
R. Brent Tully reported the findings of his investigation into the underlying structure of the LS in a detailed 1982 paper. It is made up of two parts: a flattened disk that contains two-thirds of the supercluster’s bright galaxies and a roughly spherical halo that contains the remaining one-third. The disk is a thin (one millionth of a millionth of a millionth of a millionth of a millionth of a millionth of a millionth of a millionth of a millionth of a millionth of a millionth of a millionth of a millionth of Astronomers have been able to compare the LS to other superclusters thanks to data from the 5-year Two-degree-Field Galaxy Redshift Survey (2dF), which was released in June 2003. The LS is a typical small-scale supercluster with a poor (low density) core. It is surrounded by filaments of galaxies and poor groups, with one rich galaxy cluster in the center. The Local Group is a tiny filament stretching from the Fornax Cluster to the Virgo Cluster on the borders of the LS. The volume of the Virgo Supercluster is roughly 7000 times that of the Local Group, or 100 billion times that of the Milky Way.
The Virgo Supercluster contains how many galaxies?
The Virgo Cluster is a tiny cluster of galaxies in the constellation Virgo, with a center distance of 53.8 0.3 Mly (16.5 0.1 Mpc). The cluster is the heart of the larger Virgo Supercluster, of which the Local Group (which contains our Milky Way galaxy) is a part. It has around 1,300 (and maybe up to 2,000) member galaxies. The Virgocentric flow is how the Local Group perceives the mass of the Virgo Supercluster. The mass of the Virgo Cluster is estimated to be 1.2.
What exactly is our cosmological supercluster?
The Virgo Cluster, Local Group, and, by extension, our galaxy, the Milky Way, are all part of the Laniakea Supercluster. It contains our galaxy, the Milky Way, as well as the Local Group. It is also known as the Local Supercluster because it contains the Virgo Cluster around its core.
What is the name of the galactic cluster in which our galaxy is located?
Our cosmos contains hundreds of billions, if not trillions, of galaxies of various forms and sizes. The most of them are far from our home galaxy, the Milky Way. Most are too far away to see without binoculars or a telescope at billions of light-years away. Our Local Group, on the other hand, is unique. Within the wide universe, it is made up of our nearby galaxies. The galaxies in the Local Group are all within a 5 million light-year radius of us. The diameter of the Local Group as a whole is around 10 million light-years. In the Local Group, our Milky Way is one of three big galaxies. However, it is not the most massive of the Local Group galaxies. That would be the galaxy of Andromeda. The Triangulum galaxy, the third of the three large ones, is the smallest of the three. The Local Group also contains about 50 dwarf galaxies. So, in our universe, is the Local Group considered a huge structure? Both yes and no. Continue reading to find out more.
The Local Group galaxies are relatively close to us on the enormous astronomical distance scale. Instead of billions of light-years, they’re simply millions. As a result, several Local Group galaxies can be seen without a telescope from a dark location.
According to the diagram above, our Milky Way galaxy is in the core of the Local Group. Of course, it doesn’t, but the image is set up that way to honor our human perspective. The Local Group, on the other hand, does have a gravitational center. Between the Milky Way and the Andromeda Galaxy, it’s located.
Our Local Group is also on the margins of a massive supercluster of galaxies known as the Virgo Supercluster, according to astronomers.

What’s bigger than the Local Group?
A group of galaxies known as the Local Group. It covers a distance of 10 million light-years. However, gravity has an endless range, despite being the weakest of the four fundamental forces of existence. It’s no surprise, then, that astronomers detect groupings of galaxies on both small and big scales when looking out into space. They perceive organizations like the Local Group as part of far larger hierarchies.
The Virgo Supercluster contains at least 100 galaxy groupings and clusters, including our Local Group. This massive supercluster, often known as our “local” supercluster, is estimated to measure 110 million light-years in diameter.
In 2014, astronomers reported that the Virgo Supercluster itself could be a member of a larger structure known as the Laniakea Supercluster. They estimated that the bigger supercluster consists of 100,000 galaxies spread across 520 million light-years. Astronomers at the time identified this massive supercluster as one of several such structures in space.
However, a group of astronomers discovered a few years later that the galaxies in the Laniakea Supercluster are not gravitationally bound. So, rather of being a confined item, they predicted that this cluster would disperse over time.
Will it succeed? We still don’t know for sure. What we do know is that gravity is at work throughout our cosmos, forming galaxies in space. Our Local Group is simply one example of how galaxies tend to gather – albeit one that we find fascinating.
Big, bigger, biggest?
The Local Group of galaxies is made up of three giant galaxies the Andromeda Galaxy (largest), our Milky Way Galaxy (second largest), and the Triangulum Galaxy (third largest) as well as 50 or so dwarf galaxies.
What has happened to the Great Attractor?
The Great Attractor is described as “an apparent gravitational anomaly in intergalactic space at the core of the local Laniakea Supercluster,” which includes the Milky Way.
Is the Virgo Supercluster home to Earth?
The Virgo Supercluster of galaxies is where Earth is located in the universe. A supercluster is a collection of galaxies bound by gravity. We are in the Local Group, a smaller group of galaxies within this supercluster. The Milky Way is the second biggest galaxy in the Local Group, behind the Milky Way.
How is the supercluster distributed throughout the universe?
Galaxies are clustered into gravitationally bound clusters rather than being spread randomly throughout the cosmos. Depending on how many galaxies they contain, these clusters are referred as either poor or rich. Poor clusters are frequently referred to as groupings. The Milky Way is part of the Local Group, a poor cluster of around 50 galaxies, including dwarf galaxies.
Superclusters, which contain dozens of clusters, are formed from clusters. Superclusters can span up to 30 Mpc. Superclusters are stacked in sheets with large spaces in between, according to recent findings, while matter in the cosmos is arranged in a filamentary form.
The Virgo Supercluster contains how many planets?
It can be found in the direction of the constellation Virgo, as its name suggests. Virgo comprises 1,300 possibly even 2,000 constituents, compared to the hundreds of galaxies in the prior groups and clusters. They total 1.2 quadrillion solar masses, which are scattered out over 7.2 million light-years.
