Space is full of adventures.
Today you
are seeing which was unseeable from
centuries.
This is the first photo of a
black hole and it's a huge milestone for
the astronomy.
You must have thousands of
questions in your mind like, what is the
black hole? why the photo of it so blurry?
can black hole destroy the earth? and do
black holes eat each other? etc..
To clear
your doubts watch this video till
the end, we bet you'll be amazed.
first of all, let's know What are these
black holes. Black holes are the stars
but the dead one, but the black hole is
similar to a vacuum cleaner cleaning up
the debris left behind in the outer
space. However, it is not a suction power
that makes things fall into a black hole.
Suction would not be strong enough
instead, a black hole uses the power of
gravity to pull things towards it.
Who
first thought about black holes.
Albert
Einstein first predicted black holes in
1916 with his general theory of
relativity.
The term black hole was
coined in 1967 by American astronomer
John Wheeler and the first one was
discovered in 1971.
How do black holes
form?
When a large star can no longer
support its heavy weight it, collapses
under its own weight. Gravity becomes so
strong that even light cannot escape it.
Even if a star passes too close to a
 black hole, it can be torn apart. When a
larger star collapses, it continues to
compress and creates a stellar black
hole. Supermassive black hole like
Sagittarius A* are made when
thousands of stellar black holes comes
together.
Why the black holes never being
captured?
How do you take a picture of something
that does not emit or reflect a light?
Till now all images were
computer-generated because despite major
advances in telescope technology there
is no single telescope can capture the
image of a black hole because they're
too small. So astronomers made a huge
telescope by syncing differently
located telescope with strong and
powerful atomic clocks. The series of
them is named as Event Horizon Telescope.
Here are some alluring facts about the
black hole recently captured. This black
hole is from galaxy named Messier 87.
The
scientists called it a monster black
hole because it's 6.5 billion times
massive than our Sun.
This black hole is
55 million light years away from us. It's
data is stored in hundreds of hard
drives which is too huge to publish.
Picture of the black hole is blurry it's
because the telescope's reached a
"fundamental resolution limit" but this
picture is highest resolution picture
ever taken.
What happens when two black
holes collide?
At collision the black
holes would release tremendous amounts
of energy. This event would virtually
destroy everything in the surrounding
that comes in the path. As black holes
have very strong gravitational fields
around them, they will produce
gravitational waves while moving around
each other.
these waves would rip apart any
celestial bodies nearby and many other
the event will take place. At last a
the supermassive black hole will be formed.
The largest black hole known to man is
S5 0014+81.
It is 40 billion times heavier in mass
than our own Sun. That is pretty massive
when you think about it.
Can black hole eat the earth?
scientifically yes, but black holes are
too far away from us. Even the nearest
black hole Cygnus x1 is six thousand
light-years away from us. Anything
including planets, stars, like our earth
and sun if sucked into the black hole
will be absorbed. That the way the black
hole's grow bigger and bigger. But don't
worry there is a limit for every black
hole, when reached the black hole will
stop growing and eject the mass it has
consumed.
Now it's our turn of asking a
question. We know that the Sun is a star.
can it be converted into a black hole?
and if yes, then can it swallow earth in
it we'll be waiting for your comments.
