Take a look at the first jaw-dropping image of the black hole ‘Enigma’ at the center of our galaxy just released by astronomers.


that much First image of a supermassive black hole at the center of our galaxy Announced by the Event Horizon Telescope (EHT). It comes from the same team of over 300 international scientists. First black hole image in another galaxy in 2019.

A dramatic new image, which astronomers call Sagittarius A* (pronounced “Sagittarius A-star”) Press conference Simultaneous event with the headquarters of the European Southern Observatory (ESO) and around the world. Ten days of rumors and speculation continue as to exactly what will be announced. It was introduced to the audience as the first image of “The Mystery” at the center of our galaxy.

You can directly download amazing images. Here Take a virtual tour to the heart of the Milky Way. Here:

Taken using a global network of 11 telescopes to create an Earth-sized telescope, this image shows the shadow of the event horizon around Sagittarius A*, rather than the actual black hole itself. Hence the name of EHT.

Black holes are huge and dense places in space where the gravitational field is so strong that even light cannot escape.

The event horizon is the boundary that marks the black hole’s limits, and is effectively the black hole’s surface. That is where an object can escape the gravity of a black hole. But beyond that, everything perishes.

With this image, EHT completed what it had planned for 2015. The result is today a. special issue ~ Of Astrophysical Journal Letters.

Geoffrey Bower, EHT project scientist at the Institute of Astronomy and Astrophysics, said: “This unprecedented observation has greatly improved our understanding of what is happening at the center of our galaxy, and that this massive black hole It gives you new insights into how you interact with your surroundings. Academia Sinica, Taipei. “We were amazed at how well the size of the ring matched the predictions of Einstein’s general theory of relativity.”

What is Sagittarius A*?

A supermassive black hole at the center of our galaxy. It spans about 22 million miles and is a powerful radio source.

It was first discovered in 1974, but has been impossible to image until now. We hope these new images will help astronomers study the properties of accretion and outflow around the center of our galaxy. We will also deepen our study of basic black hole physics.

Where is Sagittarius A*?

About 27,000 light-years from us, Sagittarius A* lies near the border between Sagittarius (Sagittarius) and Scorpio (Scorpio). It’s in the black dusty lane in the Milky Way image above.

However, today’s image provides the first direct visual evidence of this.

Below is a map of the center of our galaxy, showing the exact location of Sagittarius A*.

What is EHT?

The Event Horizon Telescope (EHT) project creates images of black holes. It simultaneously uses a global network of radio observatories to effectively create an Earth-sized telescope.

The following 11 telescopes are used around the world.

What about the old black hole image?

In 2019, EHT released the first image of a black hole at the center of the supermassive elliptical galaxy M87 in the constellation Virgo. It revealed a bright ring-like structure with a dark central region that was the shadow of a black hole.

The second largest black hole from Earth is about 1,000 times larger than the black hole in our galaxy, but 2,000 times more distant.

Early images released in 2019 Updated in 2021 to include polarization around the M87 black hole.

Polarized images like these are key to understanding how magnetic fields can allow black holes to “eat” matter and launch powerful jets.

However, the two black holes photographed by the Event Horizon Telescope (EHT) collaboration are very different. Our own Sagittarius A* black hole is more than a thousand times smaller than the black hole at the center of galaxy M87.

“We have two completely different types of galaxies and two very different black hole masses, but when we get close to the edge of these black holes, they look remarkably similar,” said Sera Markoff, co-chair of the EHT scientific committee and professor of theoretical astrophysics. said. at the University of Amsterdam, Netherlands. “This tells us that general relativity dominates these objects up close, and that the differences we see further away must be due to differences in the matter surrounding the black hole.”

Hope you have clear skies and wide eyes.
