1. Largest Planet (Super Jupiter)
A planet 13 times more massive than Jupiter, the largest planet in our own solar system. he planet orbits a star called Kappa Andromedae that is 2.5 times the mass of the sun and is located 170 light-years away from Earth
2. Largest Star
There is some confusion here because currently there are 2 largest stars that have been discovered to date. But they are considered the largest in different ways.
(R136a1 mass and brightnes.)
163,000 light-years away, located at the center of R136 cluster of stars. It is the most luminous star known, radiating more energy in five seconds than the Sun does in a year. If it replaced the Sun in our Solar System, it would outshine the Sun by 94,000 times. It is also 265 times the sun’s mass.
VY Canis Majoris (Size)
At one time it was the largest known. Has a diameter of 1,976,640,000 km. It’s at (3,900 light-years) from Earth.
3. Largest Asteroid (Ceres) — Pronounced “Seh-reeze”
It is about one-quarter the size of the moon and orbits the sun between Mars and Jupiter in a region called the asteroid belt. Ceres was discovered by the Italian priest astronomer Giuseppe Piazzi in 1801. It was the first asteroid ever discovered.
4. Largest Black Hole
A monster supermassive black hole. Scientists say the newfound black hole SDSS J010013.02+280225.8 is the largest and brightest ever found.with a mass about 12 billion times than the sun. It is about 429 trillion times brighter than the sun. 12.8 billion light years from earth.
5. Largest Galaxy (IC 1101)
The single largest galaxy that has ever been found in the observable universe. It is located almost a billion light-years away. Its located at the at the center of the Abell 2029 galaxy cluster, To give you some idea of what this means, the Milky Way is just 100,000 light-years in diameter, and IC 1101 is 2000x as massive.
6. The Mysterious Supervoid
Mysterious ‘supervoid’ in space is largest object ever discovered, scientists claim. Astronomers have discovered a curious empty section of space which is missing around 10,000 galaxies.
The ‘supervoid’, which is 1.8 billion light-years across, is the largest known structure ever discovered in the universe but scientists are baffled about what it is and why it is so barren.
7. Newfound Blob -LYMAN ALPHA BLOBS or LAB
It first made its presence known in the year 2000 and we know it’s located some 11.5 billion light years away. What will really get your attention is the size. LAB-1 has a diameter of about 300,000 light-years across
A team of astronomers were checking out areas of the Universe where matter was the most dense – home to huge and very bright and rare structures called Lyman-alpha blobs. While there wasn’t anything in particular they were looking for, what they captured was something unique… evidence of polarization.
Matthew Hayes (University of Toulouse, France) says, “We have shown for the first time that the glow of this enigmatic object is scattered light from brilliant galaxies hidden within, rather than the gas throughout the cloud itself shining.”
8. Shapley Supercluster
Shapley Supercluster or Shapley Concentration (SCl 124) is the largest concentration of galaxies that forms a unit of the same gravitational function. This causes the cluster to pull itself together instead of expanding with the universe. It appears in the constellation of Centaurus. It is 650 million light years away
9. The Cosmic Web
Stars are organized into galaxies, which in turn form galaxy groups, galaxy clusters, superclusters, sheets, walls and filaments, which are separated by immense voids, creating a vast foam-like structure sometimes called the “cosmic web”. The spread out “cosmic web” of gas that stretches between galaxies. So although we may not be able to see, galaxies in the universe are connected. Making them in many cases alot biger structers than can be visibly seen. It is unknown just how large the comic web actually extends. But the area that scientists have observed extend over at least 60 million
10. Biggest Thing in Universe
Dr. Jon Hakkila, an astrophysics professor at the College of Charleston in South Carolina and one of the astronomers who discovered the structure says, “The Her-CrB GW is larger than the theoretical upper limit on how big universal structures can be,” . “Thus, it is a conundrum: it shouldn’t exist but apparently does.” Because astronomers are still mapping the sky, there just may be something even grander than the Hercules-Corona Borealis Great Wall in our universe.
