There are many stars like the Sun, many constellations like Alpha Centauri, many other solar systems like our solar system, and many planets in the whole universe. Apart from this, the Blackhole is called the demon of space and many largest things in the universe are also present.
Want to know about the biggest things in the universe? Yes! So these are the largest astronomical things in the universe –
8. The Blob
Discovered in 2006, "The Blob" was known at that time to be the largest object in the universe and named Lyman Alpha Blob. The Blob is made of gas, dust particles, and galaxies and is 200 million light-years wide and 10 billion light-years from Earth. Its shape is like Jellyfish. Japanese scientists believe that this is the first thing made in the universe that emerged roughly 2 billion years after the universe theoretically experienced the Big Bang. Its huge size also connects many galaxies.
7. The Laniakea Supercluster
Many galaxies present in space together with other galaxies present around them form a group called a cluster. Further, many such clusters join together to form a supercluster, and where the supercluster is formed; That place remains very dense.
Our Milky Way galaxy was previously believed to be part of a supercluster named "Virgo". But according to the new discovery, our galaxy is now considered to be part of the largest supercluster in the universe known as "the Laniakea Supercluster".
The length of this supercluster is 520 million light years and it is the new and only accurate address of our Earth in this large universe.
6. The Great Wall
You must have heard about the world's largest wall "The Great Wall of China" present in China. It is one of the wonders present in the world. But do you know about "The Great Wall" present in space? If not, let us tell you about it.
This celestial object discovered by American scientists is 500 million light-years long and 16 million light-years wide. Let me tell you more here that its shape is similar to that of the "Great Wall of China".
Most of the large celestial bodies and things present in the universe have a lot of distance between them. That's why scientists measure the distance between any two celestial objects, using the Light Spectrum.
5. The Sloan Great Wall
We have already discussed a Great Wall present in space. But now the wall this wall is really unique. Its shape itself makes it very unique. The "Sloan Great Wall" discovered in 2003 is a celestial structure made up of many superclusters.
Its size is about 1.37 billion light-years. It is approximately 1/60 of the diameter of the observable universe. Due to such a large size, scientists have not discovered much about it. But let me tell you that the rules of common physics do not work here, because there are many more secrets beyond physics.

4. The Supervoid
Scientists have found a big empty space in the universe. Which is named "The Super Void". It is present near the series of stars named "Eridanus". Its size makes it one of the largest things in the universe.
Its size is about 1.8 billion light years. You will not see the presence of any kind of celestial object in this empty space. Apart from this, due to being so large in size, it also comes in the list of things that may be the biggest mystery of the universe.
Apart from this, these types of "Voids" make up 50% of our space and 30% make up galaxies. The remaining 20% of other celestial objects together complete the structure of the universe.
Many scientists also call a "Supervoid" a "Cold Spot", where no radiation of any kind can flow. This place is most mysterious, cold, and full of darkness. Some scientists also believe that the "Parallel Universe" exists around this "Cold Spot".
3. The Huge LQG
A quasar is an astronomical structure present in the center of BlackHole. The energy present inside this structure is the most powerful energy in the entire universe. Apart from this, along with being powerful, quasars are very large in size.
The third largest object present in the entire universe is a group made up of many quasars. Scientists have named this group "The Huge LQG".
Its size is about 4 billion light-years, which is approximately 1600 times greater than the distance from the Milky Way to Andromeda and it contains 72 to 74 quasars.
2. The Giant GRB Ring
The universe is very vast and the objects present inside it are also very large. For example, we can consider the "Giant GRB Ring". This ring is 5.6 billion light-years long and is the second-largest astronomical structure in the universe. GRBs ring lies at a distance of about 9.1 billion light-years from Earth.
Gamma rays radiation in space is a very rare thing. One unique thing about “Giant GRB Ring” that makes it even more unique is its shape. The Giant GRB Ring is a ring of 9 gamma-ray bursts, this ring is quite familiar in space for its strange shape.
The shape of the "GRB Ring" from our Earth is like a ring (its shape can be of other types) and it was formed only 250 million years ago and discovered in July 2015. Well, a question arises in the minds of the scientists, after all, how was the structure of such a big ring possible? So, in response to this, many scientists consider Dark Matter itself responsible for the "GRB Ring".
1. The Hercules Corona Borealis Great Wall
Now it is the turn of the largest thing in the universe. In today's space, scientists have discovered the biggest thing in space through Gama Ray Bursts. So, the biggest thing in the whole universe is "The Hercules Corona Borealis Great Wall". Its size is 10 billion light years.
This Great Wall is made up of a group of many "GRB Rings" and it is also considered to be the densest place in the whole universe.
Due to such a large size, scientists have not yet been able to properly test this astronomical object present in this large space. Some scientists also believe that, if this Great Wall is detected properly, it can answer every single question related to the formation of our universe.
