Zoom in to our black hole seen in a new light
Ғылым және технология
This zoom video takes you to Sagittarius A*, the supermassive black hole at the centre of our galaxy, seen now for the first time in polarised light. The video begins at the Atacama Large Millimeter/submillimeter Array (ALMA), a telescope in which ESO is a partner and that is part of the Event Horizon Telescope (EHT). As we zoom into the heart of our galaxy, we switch from visible to infrared light to peer through the dense clouds of dust in this region. We see some stars orbiting very close to Sgr A*, observed with ESO’s Very Large Telescope Interferometer. Finally, we arrive at Sgr A*. The first image of this black hole was released in 2022. The swirling lines overlaid in this new image mark the orientation of polarisation, which is linked to the shape of the magnetic field around the black hole.
The various observations used here were taken at different times, by different teams and with different facilities, and put together for the purpose of the zoom effect. The images go from visible wavelengths at the beginning to infrared, with the very final image being taken at radio wavelengths.

It's amazing that you guys have been uploading videos regularly! I want more ❤
That zoom hits different seeing the absolute scale of our universe

I don't get it. Why does m87 black hole and Sagittarius blackhole looks same? Plus in the previous video of Sagittarius blackhole, no light was shown. Then how does this have light.@@ESOobservatory
Blows my mind that I've been able to know about and "see" a black hole! Thanks so much for posting!!! v
Cheers 👍💪✌
Best video on youtube
Superbe 😍
🙌Sgt A*!
Esta música é perfeita...para nos levar nesta viagem à velocidade de 52 segundos ao encontro do buraco negro que nos encandeia de luz!!
I love the bgm

The ELT WEB cams have had a lousy slow updating for a long time and now they do not work at all. Is there work done now to make it better or has it been shut down permanently?
VERY HIGH Beings come from Sagittarius. Its the constellation you want to lay attn to the most. Every now and them they will allow you to see them.
0:34: Is there just one star perfectly aligned with us and SgrA*?

That is Sgr A* itself as seen with our Very Large Telescope Interferometer in infrared light. The VLTI uses our four 8.2-m telescopes at Paranal Observatory linked together. These observations were used to track the motions of stars around the black hole. But to see the shadow itself we need the Earth-sized Event Horizon Telescope. You can learn more about those VLTI observations here: www.eso.org/public/news/eso2119/

@@ESOobservatory, Thanks for the link. It'd be wonderful to visit the telescope when I'm in the neighborhood. 😊 I'll be sure to ring you folks up! Really though, what a fascinating "job" to have. The universe is truly AMAZING. Thanks for posting. v
Oh
This is how the black hole looked like 26 000 years ako

As long as there's no preferred direction for light. Surprisingly there is no way to prove this. It could be that light travels instantly from the direction of the center of the galaxy, but takes 52,000 years to go the other direction. In theory there is no way to tell the difference between this and a universe where light travels equally fast in all directions. It would look exactly the same either way. Light is trippy.
"Our black hole" A black hole which is on our side?😊
Same image used for 5 years.
Are human brain and present knowledge capable of understanding the scheme and working of the Universe/ Multiverse....???
XD
Is this real???

It is! The video contains real images of the night sky at progressively smaller scales, taken with different telescopes at different wavelengths or "colours" of light. The final image was obtained with the Event Horizon Telescope, a worldwide network of radio telescopes. The lines overlaid on the image mark the orientation of polarised light, which tells us about the shape of the magnetic field around the black hole.

It's as real as you are. The technology is such that we mere mortals now have to see wonders and mysteries the universe has. Let that sink in...v

It’s real. The original photo was a little less detailed from over a year ago. They also have some time lapse video that shows stars zipping around the black hole taken over a period of 8 years or so. The new telescope in chile has tons of data proving this.
nonsense. this is nothing more than a computer generated ai fantasy generated image of nothing. its no diff than an artist rendering except its a computers rendering and a computer can only do what a human programs it to do so its still a human rendering of whatever a human thinks is there.
