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.

How wide is the biggest black hole?
In 2012, astronomers reported an unusually large mass of approximately 17 billion M ☉ for the black hole in the compact, lenticular galaxy NGC 1277, which lies 220 million light-years away in the constellation Perseus.
How big is the smallest black hole?
NASAscientists have identified the smallest, lightest black hole yet found. The newlightweight record-holder weighs in at about 3.8 times the mass of our sun andis only 15 miles (24 kilometers) in diameter.
What is the diameter of the black hole at the center of the Milky Way?
Researchers spotted about a dozen black holes lurking at our galactic center—and there may be up to 10,000 more. At the center of our Milky Way galaxy, sits a supermassive black hole called Sagittarius A*, which has a mass that is 4 million times that of our sun.
What is the closest black hole to Earth?
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.
What is the largest black hole?
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.
Is there a limit to black hole size?
Black holes have a size limit of 50 billion suns. Even gluttons can’t eat forever. When black holes at the hearts of galaxies swell to 50 billion times the mass of our sun, they may lose the discs of gas they use as cosmic feedlots. Most galaxies host a supermassive black hole at their centre.
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.
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 humans make a black hole?
But if black holes are produced, then the theory of general relativity is proven wrong and does not exist at these small distances. The rules of general relativity would be broken, as is consistent with theories of how matter, space, and time break down around the event horizon of a black hole.
Is a wormhole possible?
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.
Can the LHC create a black hole?
Although the Standard Model of particle physics predicts that LHC energies are far too low to create black holes, some extensions of the Standard Model posit the existence of extra spatial dimensions, in which it would be possible to create micro black holes at the LHC at a rate of the order of one per second.
What is the black hole at the center of the Milky Way called?
The complex astronomical radio source Sagittarius A appears to be located almost exactly at the Galactic Center (approx. 18 hrs, −29 deg), and contains an intense compact radio source, Sagittarius A*, which coincides with a supermassive black hole at the center of the Milky Way.
How big is the universe?
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
What is the diameter of Sagittarius A?
44 million km
What is inside a black 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.
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.
How many black holes have been observed?
Black holes detected by gravitational wave signals. As of February 2019, 10 mergers of binary black holes have been observed. In each case two black holes merged to a larger black hole. In addition, one neutron star merger has been observed (GW170817), forming a black hole.
Why do stars collapse?
The compression caused by the collapse raises the temperature until thermonuclear fusion occurs at the center of the star, at which point the collapse gradually comes to a halt as the outward thermal pressure balances the gravitational forces. The star then exists in a state of dynamic equilibrium.
How many solar masses is a black hole?
10 solar masses
How many galaxies are in the Bootes Void?
Why do black holes have event horizons?
An event horizon is most commonly associated with black holes. Light emitted from inside the event horizon can never reach the outside observer, and the outside observer cannot see beyond the event horizon.
How distant is ULAS J1342+0928?
ULAS J1342+0928 is the eighth-most distant astronomical object by redshift (z = 7.54). The top 10 most distant astronomical objects are: GN-z11, MACS1149-JD1, EGSY8p7, A2744 YD4, GRB 090423, EGS-zs8-1, z7 GSD 3811, ULAS J1342+0928, z8 GND 5296, A1689-zD1.
Does the sun rotate around Earth?
Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi), and one complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). Earth’s orbit has an eccentricity of 0.0167.
Would a black hole kill you?
In the previous case objects would actually be destroyed and people killed by the heat, not the tidal forces – but near a black hole (assuming that there is no nearby matter), objects would actually be destroyed and people killed by the tidal forces, because there is no radiation.
Is time travel possible backwards?
However, making one body advance or delay more than a few milliseconds compared to another body is not feasible with current technology. As for backwards time travel, it is possible to find solutions in general relativity that allow for it, but the solutions require conditions that may not be physically possible.
Is exotic matter real?
In physics, exotic matter is matter that somehow deviates from normal matter and has “exotic” properties. A broader definition of exotic matter is any kind of non-baryonic matter—that is not made of baryons, the subatomic particles (such as protons and neutrons) of which ordinary matter is composed.
What is the Large Hadron Collider used for?
The aim of the LHC’s detectors is to allow physicists to test the predictions of different theories of particle physics, including measuring the properties of the Higgs boson and searching for the large family of new particles predicted by supersymmetric theories, as well as other unsolved questions of physics.
What was the Hadron Collider built for?
The Large Hadron Collider (LHC) is the world’s biggest and most powerful particle accelerator. It was built by the European Organization for Nuclear Research (CERN). It is a giant circular tunnel built underground.
What are quarks made of?
A quark (/kwɔːrk, kwɑːrk/) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.
