How scientists captured the first image of a black hole, Scientists shoot black hole for the first time and the event is just surprising. Scientists have finally managed to capture an image of a black hole.
The Event Horizon Telescope (EHT) consortium, after 13 years have managed to take the first-ever image of a black hole, which is located in a distant galaxy, with a network of eight telescopes across the world.
Details of the black hole
- 1. The black hole that has been photographed is called M87 and is three million times the size of the Earth.
- 2. M87 measures 40 billion km across
- 3. The black hole is 500 million trillion km away
It shoulda magnitude of 6.5 billion times that of the Sun. Also, it’s one of the heaviest black holes that we believe exists. It is an entire monster, the heavyweight champion of black holes in the Universe.
Anand Ranganathan took to Twitter to make the big announcement. Said, “Two times to one of the various momentous scientific events in current memory. Scraps everything you have prepared for the next few of hours and bless your time and work on it.”
Prof Falcke has the perfect description for it. He describes the photograph as an intensely bright “ring of fire” around a perfectly circular dark hole. According to BBC, the professor said that the bright halo is caused by superheated gas falling into the hole.
The gas enters the black hole from the edge of the dark circle at the centre. The light is more luminous than all the billions of different stars in the universe consolidated. which is why it can be observed at such distance from Earth.
Why was it such a difficult feat?
No one could take photographs of a black hole’s interior because any light that comes too close to it gets sucked by its gravitational pull. Prof Falcke said that the “ring of fire” formed the gases is brighter a combination of all the billions of other stars in the galaxy and that is why it could be seen from such a distance.
That is how the original image of a black hole accumulates up to artists’ impressions.
Until recently, the only way to picture a black hole was to imagine what that incredibly dense object might look like or take a look at a talented artist’s interpretation. Now, thanks to a worldwide effort involving hundreds of researchers and eight telescopes spread across five continents.
The research community finally has an actual snapshot of a black hole, pictured in silhouette. The image is of the black hole at the centre of the galaxy Messier 87, which is around 55 million light-years away from Earth.
The image is magnificent if a little blurred but how does it hold up to the meticulously crafted images created by both artists and computers in the BBH (Before Black Hole) era? To be quite honest, it doesn’t have some of the panache, colour, or bright detail as the imagined versions.
But it does have a black hole, and really, what more could we want? Still, while we wait for more telescopes to come online and more photographs to be taken, it’s fun to take a look at how we’ve envisioned these cosmic phenomena in the past.

Snapshot of the black hole
Here it is! The very first picture of a black hole. At six press conferences at the same time in Bruxelles, Washington, Taipei, Tokyo, Shanghai, Santiago American state Chile researchers conferred the outstanding photo: A dark circle with a flaming orange ring of light.
The researchers couldn’t do this with a telescope. A telescope of this size would have to be as large as the Earth. Because this is impossible, the researchers came up with a trick. They connected eight-strong radio telescopes around the globe to simulate a large telescope.
Since 2017, they need collected information on information, packed them along and were ready to prove with an image what Einstein had already calculated one hundred years ago: that there must be something with such a mass that it attracts, swallows and distracts from its orbit anything close to it.
This photo, conferred by researchers from the international research Event Horizon Telescope, is groundbreaking. A new era, as Carlos Moedas, the EU’s research commissioner, put it in Brussels. That is true. It would be worthy of a Nobel Prize.
Because black holes area unit what they’re called: black, dark, invisible. Black holes have such an oversized mass that they swallow something that approaches them. They even swallow their light, so they are not visible. The gravity of black holes is unimaginably great.
Why do researchers know that black holes exist?
These distractions can be measured by researchers. They grasp that there should be one thing huge, one thing of mammoth power, doing its work.
How are black holes formed?
In very different ways. For example, when a massive star dies, it explodes. Researchers call this a supernova. The star repels its outer layers whereas the remainder collapses, leaving behind a relatively small black hole that no longer lets any light escape due to its mega-mass.
They can have millions or billions of times the mass of our sun. They are at the centre of most galaxies, including our Milky Way. Researchers do not yet know how they were formed. They suspect that many black holes might have united there.
Why are black holes so important?
Which black holes do you need to know about?
The international analysis team in Hawaii, Arizona, Spain, Mexico, Chile and at the South Pole has been observing and measuring a few since 2017. The entirety is Sagittarius A, a supermassive black hole in the core of our Milky Way. Sagittarius A is 26,000 light-years away from Earth and over four million times more massive than our Sun.
The second candidate is that the supermassive region within the big galaxy M87 within the Virgo cluster. It is even further away from us, namely 55 million light-years (if you can still imagine that) and it has 6.6 billion solar masses.
