The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall.
It was first reported in 2013 and has been studied several times.
It’s so big that light takes about 10 billion years to move across the structure.
Where is the biggest black hole in the universe?
Astronomers have discovered what may be the most massive black hole ever known in a small galaxy about 250 million light-years from Earth, scientists say. The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus.
What is the biggest thing in the solar system?
Our solar system is always in motion. Eight known planets and their moons, along with comets, asteroids, and other space objects orbit the Sun. The Sun is the biggest object in our solar system. It contains more than 99% of the solar system’s mass.
Is VY Canis Majoris or Uy scuti bigger?
On a stellar scale, it’s really quite average — about half of the known stars are larger; half are smaller. The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
What is the oldest thing in the universe?
With a redshift of z = 8.2, at the time of observation, the burst was the most distant known object of any kind with a spectroscopic redshift. GRB 090423 was also the oldest known object in the Universe, as the light from the burst took approximately 13 billion years to reach Earth.
What is a white hole NASA?
In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escape.
Where is the closest black hole?
The closest black hole we know of is V616 Monocerotis, also known as V616 Mon. It’s located about 3,000 light years away, and has between 9-13 times the mass of the Sun. We know it’s there because it’s located in a binary system with a star with about half the mass of the Sun.
Is the sun bigger than Jupiter?
Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter’s radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar.
What is there above the sky?
The sky (or celestial dome) is everything that lies above the surface of the Earth, including the atmosphere and outer space. In the field of astronomy, the sky is also called the celestial sphere. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae.
What is bigger than a supercluster?
Superclusters form massive structures of galaxies, called “filaments”, “supercluster complexes”, “walls” or “sheets”, that may span between several hundred million light-years to 10 billion light-years, covering more than 5% of the observable universe. These are the largest known structures to date.
How did VY Canis Majoris get its name?
The first known recorded observation of VY Canis Majoris is in the star catalogue of the French astronomer Jérôme Lalande, on 7 March 1801, which lists it as a 7th magnitude star. It was given the variable star designation VY Canis Majoris in 1939, the 43rd variable star of the constellation Canis Major.
Is the sun the biggest star in the universe?
The extreme red hypergiant star VY Canis Majoris compared to the Sun and Earth’s orbit.
Where is VY Canis Majoris?
RA 7h 22m 58s | Dec -25° 46′ 3″
What is the oldest thing alive?
Methuselah, a Great Basin bristlecone pine (Pinus longaeva) is measured by ring count to be4,850 years old. This is the oldest known tree in North America, and the oldest known living individual nonclonal tree in the world. The Cypress of Abarkuh is estimated to be between 4,000 and 5,000 years old.
How old is the youngest star in the universe?
Age and distance
| Title | Object | Data |
|---|---|---|
| Oldest star | HD 140283 | 14.5±0.8 billion years |
| Youngest | Stars are being formed constantly in the universe so it is impossible to tell which star is the youngest. For information on the properties of newly formed stars, See Protostar, Young Stellar Object and Star Formation. |

What is the oldest black hole?
The related black hole of the quasar existed when the universe was about 690 million years old (about 5 percent of its currently known age of 13.80 billion years). The quasar comes from a time known as “the epoch of reionization”, when the universe emerged from its Dark Ages.
Can wormholes exist?
Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. A wormhole could connect extremely long distances such as a billion light years or more, short distances such as a few meters, different universes, or different points in time.
Is a black hole a hole?
A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
What is Spaghettification in black hole?
In astrophysics, spaghettification (sometimes referred to as the noodle effect) is the vertical stretching and horizontal compression of objects into long thin shapes (rather like spaghetti) in a very strong non-homogeneous gravitational field; it is caused by extreme tidal forces.
How many black holes are there?
Unlike with stellar mass black holes, one would not experience significant tidal force until very deep into the black hole. Some astronomers have begun labeling black holes of at least 10 billion M ☉ as ultramassive black holes. Most of these (such as TON 618) are associated with exceptionally energetic quasars.
Is there a black hole near Earth?
This list contains all known black holes relatively near the Solar System (within our Milky Way galaxy). To make it easier to compare distances, our nearest star aside from the Sun – Proxima Centauri – is about 4.24 light years away and our Milky Way galaxy is 180,000 light years in diameter.
Do black holes spin?
Rotating black holes are formed in the gravitational collapse of a massive spinning star or from the collapse or collision of a collection of compact objects, stars, or gas with a total non-zero angular momentum. In late 2006, astronomers reported estimates of the spin rates of black holes in The Astrophysical Journal.
What is the great attractor in space?
The Great Attractor is an apparent gravitational anomaly in intergalactic space at the center of the local Laniakea Supercluster, in which the Milky Way is located, in the so-called Zone of Avoidance that is very difficult to observe in visible wavelengths due to the obscuring effects of our own galactic plane.
What is a group of universes called?
The multiverse, also known as an omniverse or meta-universe, is a hypothetical group of multiple universes. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, and the physical laws and constants that describe them.
How many galaxies are in the Laniakea supercluster?
100,000 galaxies
How old is VY Canis Majoris?
8.206 million years
How far away is Canis Majoris?
4,892 light years
How big is VY Canis Majoris?
987.89 million km
Is Sun a star or planet?
The Sun is the Solar System’s star and by far its most massive component. Its large mass (332,900 Earth masses), which comprises 99.86% of all the mass in the Solar System, produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium, making it a main-sequence star.
Is the sun and moon a star?
The Moon’s apparent size in the sky is almost the same as that of the Sun, since the star is about 400 times the lunar distance and diameter. Therefore, the Moon covers the Sun nearly precisely during a total solar eclipse.
Why is the Pistol Star Blue?
The Pistol Star is a blue hypergiant star; one of the most luminous known in the Milky Way. It is one of many massive young stars in the Quintuplet cluster in the Galactic Center region. The star owes its name to the shape of the Pistol Nebula, which it illuminates.
Is VY Canis Majoris the same as Sirius?
Canis Major contains Sirius, the brightest star in the night sky, known as the “dog star”. It is bright because of its proximity to the Solar System. The red hypergiant VY Canis Majoris is one of the largest stars known, while the neutron star RX J0720.4-3125 has a radius of a mere 5 km.
How close is VY Canis Majoris?
VY Canis Majoris is the 14th-nearest supernova candidate by distance (3930+420 light years). The top 10 supernova candidates are: IK Pegasi, Spica, Alpha Lupi, Antares, Betelgeuse, Pi Puppis, Rigel, Gamma Velorum, Deneb, 119 Tauri.
