First Image of a Black Hole!

First Image of a Black Hole!


This is the first-ever image of a black
hole released by the Event Horizon
Telescope collaboration on April 10th
2019
It shows plasma orbiting the
supermassive black hole at the center of
the galaxy M87. The bright region shows
where plasma is coming towards us and
since it’s traveling near the speed of
light it appears brighter when coming
towards us and dimmer when going away.
This is called relativistic beaming.
From the images scientists can tell that the
plasma is orbiting clockwise. It takes
around 2 days for the plasma to complete
one orbit. Here we are looking at the
black hole using electromagnetic waves
with a wavelength of 1.3 millimeters –
radio waves. This was the part of the
spectrum used to make the image because
it can show us the features close in to
the event horizon and it can pass
through the accretion disk and
interstellar dust to reach our
telescopes. The supermassive black hole
in M87 is very active meaning it’s
constantly feeding on lots of matter
from its glowing hot accretion disk, but
it also has narrow collimated jets above
and below it here shown in blue, thought
to be created by incredibly strong
magnetic fields. The jets extend out at
least 5,000 lightyears and one of them
appears to be pointing almost straight
at us.
Relativistic beaming is again the reason
we can see the jet coming towards us in
this Hubble Space Telescope image but
not the one going away.
Since the jet is pointed almost straight
at us I’m thinking our perspective is
almost perpendicular to the accretion
disk but let’s have a look at what we
would see if we were looking at
different orientations. The warping of
space-time around the black hole means
we can see light even from parts of the
accretion disk behind the black hole.
They are lensed above and below the shadow region.
Not gonna lie this is so trippy I
could stare at it for a long time. So the
big question most people are going to be
asking is why is the image so fuzzy?
The answer is because it’s so tiny.
Don’t get me wrong the black hole itself is
huge, supermassive in fact. As measured
from this picture the black hole has a
mass 6.5 billion times that of our Sun.
The actual size of its shadow is nearly
the size of our solar system, but located
fifty three and a half million light
years away its size from our perspective
is only about 40 micro arcseconds –
that’s the angle it makes on the sky.
To understand what that means
take the whole sky and divide it into
180 degrees. Then divide a degree into 60
arcminutes and an arcminute into 60
arcseconds. Divide an arcsecond into a
hundred
and into a hundred again
and into a hundred once more and that is the
size of the black hole shadow only about
40 micro arcseconds. It puts us at the
very limit of what we are
technologically capable of seeing. In
fact to get this sort of resolution due
to the basic law of physics the
diffraction limit we needed a telescope
the size of the Earth. That being
impractical the scientists used eight
telescopes spread across the globe. They
all simultaneously observed M87 and as
the earth rotated that helped fill in
the earth-sized telescope that they were
trying to simulate. But M87 was not the
only black hole they looked at. They also
observed the supermassive black hole at
the center of our Milky Way galaxy,
Sagittarius A* – they haven’t yet release an image of this black hole, but this simulation shows what it might look like.
it’s much closer at
around 26,000 light years away but also
much smaller with a mass only four
million times that of our Sun. It’s also
less active, only periodically gobbling
up matter, and it would have much more
variation over time with matter orbiting
every four to thirty minutes.
That’s probably why we’ll have to wait a little longer to see the black hole at the center of our galaxy.
For now, the striking image of the black hole in M87
confirms beyond a shadow of a doubt that black
holes do exist.
The general theory of relativity published over a hundred
years ago is supported again in
spectacular fashion in the strongest
gravities and
at the limits of our ability to test the
theory.
What I love about moments like this
is the ridiculous
extreme things these scientists did
these 200 scientists in pursuit of a
goal that seemed impossible and yet they achieved it.
I want to extend my personal
congratulations to everyone on the team
for an amazing discovery. I’ll be linking
to all their work in the description

100 thoughts to “First Image of a Black Hole!”

  1. Thanks & Congratulations to each & every one who are related to this discover 😊. Well done!!! Lots of love from Bangladesh.

  2. For people who complains about the quality of the photo, that's like light years away, and me picturing just 1 meter away using my phone has a much more worse quality

  3. We are really limited in intelligent people for this it takes super intelligent internet YouTube it’s way to many topics to much bad images

  4. "This is the first ever image of a black hole" lol, no it's not, it is what your scientists "think" is a black hole, and that name…."Black Hole". You Humans are funny, you think that a black hole would even have a viewable event horizon, one you can see? Do you Humans really think you can see a black hole on its side….? "NASA Wants You to Know That Black Holes Are Even Crazier When Viewed from the Side"……Silly Humans, you have so much to learn. I will say one thing, humans are never dull and always entertaining.

  5. so what would happen if the black hole nearest us stopped gobbling up matter? what would happen if it stopped spinning or slowed down drastically?

  6. It all must be true and real because the animation shows us quite clearly that it obviously is true and real.

    "It's beyond a shadow of a doubt!"…pheeeew!!!…I was worried there for a moment…silly me!

    PEACE.

  7. Black holes have no mass, they are no pressure points in the middle of a galaxy. When stars fall directly into them they release all their energy at once causing a quasar due to them not having any pressure to contain the energy. A vortex has no pressure in the middle so this is basically the vortex in spacetime due to the mass of an entire galaxy.
    Also i could elaborate more and i could be wrong in a sense, the accretion disk is where the "mass" is pulling the star apart in relation to the plain of inertia of the disk. If something like a singularity was truly infinite in mass then the sizes of black holes would all be the same in my mind, not correlating with the size of its galaxy.

  8. People: Its blur I can't set it properly

    Me: Its so far away dude the far is just how far you and your KPOP idol are

    People: So far away

  9. Mainstream data compilation fed to a computer to form that………image. There is no instrument on or above Earth, with enough definition to take such an image, no radio telescope array nor even the James Webb telescope ……. that isn't up there yet. So, please wait until mainstream science really has some truth in their findings.

  10. This is why it’s so hard to believe in God, because how can you dispute the raw and unadulterated truth? 👌 this is amazing…

  11. If the universe is (5 billion?) Years old. How many light years old would it be or is it measured in them? Because we measure distance in light years and if something was 1 billion light years away that means that it was there before the universe was created.

    Also all the stars and stuff we see are light years old and are probably gone maybe.

    If we traveled through space faster than the speed of light. Like 100x the speed of light or something and we go out far enough with a super powerful telescope couldn’t we see the earth before the dinosaurs and then if we move closer we could the dinosaurs? And if so could we see the asteroid hit the earth and see were it came from by following it back in time.
    This would be very hard and one would need incredible amounts of energy and speed to do so. But isn’t this technically possible???

  12. Wow there's 2.9K noobs/stupid people who doesn't understand Science. ಠಗಠ. Anyway this is a grand discovery of 21st century. Yay Scientists

  13. This black hole light travels millions of light years…
    Via empty space…
    Via solar system…
    Via earth…
    Via telescopes…
    Via internet…
    Via phones…
    And finally to our eyes.

    Just WOW

  14. Dr. P.-M. Robitaille,

    April 10th, 2019 – Claims of a Black Hole Image: the Day Astrophysics Died,

    Sky Scholar,

  15. And to think that image is not how it currently looks. That image took 53 million years to reach the telescope network. We are in fact looking at how the black hole looked before humans were around.

  16. OHHHH it’s all starting make sense. The black hole is devouring all masses in its way which is preventing season 11 from dropping!!!

  17. I don't want to ruin anyone else's day, but is it weird that the first time i saw this image, that i was on a rule 34 site and someone had substituted this image for the anus on a anime character and i just wanted to know did anyone else see that, and apparently there's also such a thing as black hole goatse. And again i'm so sorry.
