Top 10 Biggest Things in the World

Big, enormous, massive, huge-the extent of anything beyond our means has always mesmerized us and left us in awe. Whether it is the huge mountains or the vast oceans, the extensiveness of nature has always amazed us. And when it comes to the gigantism of our Universe, all these elements appear microscopic or tiny specks in the cosmic web. The Universe is vast, and trying to measure its vastness is mind-boggling. We will discuss about the biggest things in the world.

Space scientists have been using the latest technologies to discover new stars, exoplanets, and newer galaxies. The sheer scale of the cosmos is hard to determine. The Universe is vast and holds a lot of big things. Below we explore the biggest things in the world in different cosmic categories.

Biggest Things In The World

1. Largest Star: UY Scuti

To most of us, the Sun is the biggest star. However, the largest existing star in the Universe is the UY Scuti. Located in the constellation Scutum, it is a hypergiant star with a radius around 1,700 times larger than the Sun. If UY Scuti were placed at the centre of the solar system, its edge would extend beyond Jupiter’s orbit. The star’s gas clouds would extend beyond the orbit of Pluto, or around 400 times the Earth-sun distance. UY Scuti is about 30 times more massive than the Sun.

2. Largest Known Planet– Jupiter

The largest planet in our solar system is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than twice the mass of all other planets of our solar system. This planet has a diameter of about 140,000 km, which is about 11 times Earth’s diameter. It is fifth in line from the Sun.

If you consider the exoplanets, TrES-4b is the largest known extrasolar planet, announced by NASA in 2007. Its mass is 0.78 times that of Jupiter’s, and it takes 3.6 days to complete one orbit of its star. It is 0.05084 AU (Astronomical Unit) from its star.

3. Largest Asteroid– Ceres

There are currently more than 8 million asteroids in the Universe. These asteroids are the rocky debris of the solar system or blown out planets or stars. Ceres is the largest asteroid discovered so far in the Universe. It is about 974 km in diameter and contains about one-third mass of the entire asteroid belt. Its massiveness has earned it the title of ‘Dwarf Planet.’

4. Largest Nebula- Tarantula Nebula

One of the biggest things in the world, A nebula is a giant cloud of dust and gas in space thrown out by the explosion of a dying star, or a supernova. The most massive known nebula is the Tarantula Nebula that stretches for more than 1,800 lightyears at its longest span. It is an enormous HII region 600 lightyears across. It is also the most active star-forming region which can cover the sky area as 60 full Moons and still be bright enoug11h to cast shadows.

The nebula houses the super star cluster R136. It is home to some of the most massive and brightest known stars, which cause this glorious nebula.

5. Largest Galaxy-IC 1101

The Universe is littered with galaxies. The largest galaxies are elliptical and may contain a trillion stars. The largest known elliptical galaxy is IC 1101 in Virgo. It is 5.8 million lightyears across in size-which is an immensely huge size. Comparing with our Milky Way, it is over 50 times the diameter. This galaxy can encompass not only the Milky Way but also the Andromeda Galaxy and much of the Local Group. Its mass can contain 100 trillion stars!

6. Largest Cluster and SuperCluster– El Gordo or ‘The Fat One.’

Stars link together to form galaxies, while galaxies clump together into clusters. The largest known galaxy Cluster is the El Gordo or ‘the fat one.’ Discovered in 2011, it has a massive mass of 3 quadrillion suns. It is located more than 7 billion lightyears from the Earth.

Superclusters are formed of several galaxy clusters. Superclusters form massive structures of galaxies, called “supercluster complexes,” “walls,” or “sheets” that may span across several hundred million lightyears. The Shapley supercluster is thought to be the largest at around 650 million lightyears. It is a collection of galaxies more than 400 million lightyears long. It is roughly 4000 times larger in size than our Milky Way and contains more than 8000 galaxies. Our Laniakea supercluster, which includes the Milky Way and our Earth, stretches over 520 million lightyears.

7. Largest Blackhole- TON 618

A supermassive black hole (SMBH) is the largest type of black hole. They can be the order of hundreds of thousands to billions of solar masses. Theoretically, they are known to exist in the centre of almost all massive galaxies. The Abell 85 galaxy cluster is home to the most massive black hole known in the Universe. This one is known as TON 618 and has an estimated mass of 66 billion suns. This is roughly two-thirds the weight of all-stars in the Milky Way. It is formed from the collisions of at least eight smaller galaxies and is located in the Holmberg 15A galaxy.  It is listed as one of the biggest things in the world.

8. Largest Quasar- Huge LQG

A quasar is an extremely active region at the centre of a galaxy that emits massive radiation. Quasars derive power from supermassive black holes. The largest existing quasar today is the Huge-LQG (Large Quasar groups). It is the third-largest structure in the Universe. In fact, it is a cluster of 73 quasars spread across over 4 billion lightyears. This quasar burns at an energy which makes it 100 times more luminous than our Milky Way.

9. Largest Void-Bootes Void

The Boötes void or the Great Nothing is an enormous, region of space, containing very few galaxies. It lies about 700 million light-years from Earth in the direction of the constellation Boötes, after which it was named. The Boötes Void is like a giant hole in the Universe. It has a diameter of about 350 million light-years across. S of today, 60 galaxies have been discovered inside this supersized void. This shows that the void is not necessarily empty space.

10. Largest Structure-BOSS Great Wall

Determining the extent of the Universe is an endless task. The Cosmic Web is thought to be a vast network of clusters, linked with filaments of dark matter and galaxies. These filaments form giant walls. The Hercules-Corona Borealis Great Wall, discovered in 2013, measures up to 18 billion lightyears in length. Astronomers have recently found a wall of galaxies 1 billion light-years across, known as the BOSS Great Wall. This wall is the largest structure observed in the Universe so far. This wall is made up of 830 separate galaxies that have formed four superclusters.

It is challenging to describe the Universe in words. Limits fail after an extent. Discoveries reveal new celestial entities. Mapping the shape of the Universe becomes a real challenge. Our cosmic web extends to limits beyond human comprehension, an endless collection of superclusters and dark matter. These are the biggest things in the world.
