10 Biggest Things in the Universe

10 Biggest Things in the UniverseOur universe is really huge. Pulsars, planets, stars, black holes, and hundreds of other objects of incomprehensible size that are located in the Universe.
And today we would like to tell you about the 10 biggest things. In this list, we have compiled a collection of some of the largest objects in space, including nebulae, pulsars, galaxies, planets, stars, and more.
Without further delay, here is a list of the ten biggest things in the Universe.
10. The largest planet.
The largest planet in the Universe is TrES-4. It was discovered in 2006, and it is located in the constellation Hercules. A planet called TrES-4 orbits a star that is about 1,400 light-years away from the planet Earth.
The planet TrES-4 itself is a sphere that consists mainly of hydrogen. Its size is 20 times the size of the Earth. Researchers claim that the diameter of the discovered planet is almost 2 times (more precisely, 1.7 times) larger than the diameter of Jupiter (it is the largest planet in the Solar system). The temperature of TrES-4 is about 1260 degrees Celsius.
9. The huge star.
By far the largest star is UY of the Shield in the constellation of the Shield at a distance of about 9500 light years from us. This is one of the brightest stars — it is 340,000 times brighter than our Sun. Its diameter is 2.4 billion km, which is 1,700 times larger than our sun, with a weight of only 30 times the mass of the sun. It is a pity that it is constantly losing mass, it is also called the fastest burning star. This is probably why some scientists consider Cygnus to be the largest NML star, while others consider vy to Be the big dog.
8. The largest black hole.
Black holes are not measured in kilometers; the key indicator is their mass. The largest black hole is located in the galaxy NGC 1277, which is not the largest. However, the hole in the galaxy NGC 1277 has 17 billion solar masses, which is 17% of the total mass of the galaxy. For comparison, the black hole of our milky way has a mass of 0.1% of the total mass of the galaxy.
7. The largest galaxy.
The mega-monster among the currently known galaxies is IC1101. The distance to Earth is about 1 billion kilometers. light-year. Its diameter is about 6 million light years and holds about 100 trillion. stars, for comparison, the diameter of the milky way is 100 thousand light years. Compared to the Milky way, IC 1101 is more than 50 times larger and 2000 times more massive.
6. The largest BLOB of Lyman-alpha (Lyman-α blob-LAB)
Lexy (drops, clouds) Lyman-alpha are amorphous bodies resembling the shape of amoebas or jellyfish, consisting of a huge concentration of hydrogen. These blots are the initial and very short stage of the birth of a new galaxy. The largest of them, LAB-1, is more than 200 million light-years wide and is located in the constellation of Aquarius.
In the photo on the left, LAB-1 is fixed by instruments, on the right-an assumption of how it might look up close.
5. Radio galaxies.
Radio galaxies are a type of galaxy that have much more radio emission than other galaxies.
4. The largest void.
Galaxies are usually located in clusters (clusters) that have a gravitational connection and expand with space and time. What is found in places where there are no galaxies? Nothing! A region of the Universe in which there is only “nothing” and is emptiness. The largest of them is the void of volopas. It is located in the immediate vicinity of the constellation volopas and has a diameter of about 250 million light years. The distance to Earth is approximately 1 billion km. light-year.
3. A giant cluster.
The largest supercluster of galaxies is the shepley supercluster. Shepley is located in the constellation Centauri and looks like a bright seal in the distribution of galaxies. This is the largest array of objects connected by gravity. Its length is 650 million light years.
2. The largest group of quasars.
The largest group of quasars (a quasar is a bright, energetic galaxy) is the Huge-LQG, also called U1. 27. This structure consists of 73 quasars and has a diameter of 4 billion. light-year. However, the great GRB wall, which has a diameter of 10 billion, also claims the championship. light-years — – the number of quasars is unknown. The presence of such large groups of quasars in the Universe contradicts Einstein’s Cosmological principle, so their research is doubly interesting for scientists.
1. Space Web.
If astronomers have disputes about other objects in the Universe, then almost all of them agree that the largest object in the Universe is the Cosmic Web. Infinite clusters of galaxies surrounded by black matter form ” nodes “and with the help of gases — “threads” that look very much like a three-dimensional web. Scientists believe that the cosmic web entangles the entire Universe and connects all objects in space.
