a

The Largest And Most Powerful Black Hole In The Milky Way Galaxy (4K UHD)

[Music]

the Milky Way is a barred spiral galaxy

made up of hundreds of billions of stars

and planets if we were able to take a

picture of it it would look something

like this

it measures a mind-boggling 120,000

lightyears across and is estimated to be

about thirteen point six billion years

old we are located in a region called

the Orion Arm which is around 26,000

light-years from the center the galactic

center can be found in the constellation

of Sagittarius and like many other large

galaxies within the universe the Milky

Way harbors a cosmic terror at its heart

a supermassive black hole

black holes are cosmic objects that are

extremely dense and exhibit immense

gravitational forces they are formed as

a result of matter collapsing in on

itself creating regions with huge

amounts of mass concentrated into an

incredibly small area

the gravitational pull of a black hole

is so strong that nothing can escape it

once the event horizon has been crossed

currently there are three different

types the stellar mass which are the

smallest

the intermediate-mass which are

somewhere in the middle and the largest

the supermassive a supermassive black

hole or SMB h for short contains between

a million and a billion times more mass

than a typical stellar-mass black hole

and can be found at the center of large

galaxies the supermassive black hole

that lurks within our galaxy's center

has been named Sagittarius a star and

has been estimated to be roughly 4.1

million times as massive as the Sun

normally the region from which

Sagittarius a star exists is shrouded by

clouds of gas and dust making the area

invisible from Earth but recently

scientists working with a new radio

telescope called meerkat released an

image described as the clearest view yet

although the supermassive black hole

cannot actually be seen due to the fact

that light cannot escape its

gravitational pull the area around it

can this is because the meerkat

telescope can pick up radio frequencies

which penetrate the dust and clouds that

exist within the Milky Way's heart

revealing this terrifying but

magnificent image of our galaxy's

supermassive black hole scientists know

that the center of the Milky Way

contains a supermassive black hole

because they have observed entire stars

zipping past an invisible object

indicating that whatever lurks at the

center holds a colossal amount of power

the only known objects discovered so far

within the universe that have this much

density and gravity are supermassive

black holes there are many theories on

how supermassive black holes form and

although black holes cannot currently be

directly observed the environment that

they exist and interact with can be one

idea is that's during the early stages

of the universe these black holes were a

lot

smaller in size then over time they

absorbed massive amounts of gas and dust

merging with other black holes growing

larger and larger until they ended up

the colossal monsters they are today

however the agreed reason for why these

supermassive black holes grow so big is

still being researched it is pretty

incredible to think that there is a

colossal black hole lurking within the

core of the Milky Way but compared to

other galaxies Sagittarius a star is

actually fairly small much larger black

holes have been discovered some

containing tens of billions more mass

than the Sun although scientists are

constantly studying black holes it is

currently still a mystery as to how they

can become so large but hopefully one

day that mystery will be solved I really
