Évènement mondial du 12 mai au sujet du centre de la Voie lactée : à quoi faut-il s'attendre ?

Évènement mondial du 12 mai au sujet du centre de la Voie lactée : à quoi faut-il s’attendre ?

In April 2019, it was expected that members of the collaboration Event Horizon Telescope (EHT) reveal the first images of the appearance of a black holein this case that of the one at the heart of the Milky WaySagittarius A*, and that of the one at the heart of the galaxy M87. Only the image of the black hole M87* had finally been presented because that of the supermassive black hole of our Galaxy had proved more difficult to obtain. But, already, that of M87* looked surprisingly like the one that Jean Pierre Luminet had been the first to realistically calculate using a computer in the late 1970s. A more accurate version was obtained about ten years later by his colleague astrophysicist Jean-Alain Marck, unfortunately died too early.

stephen hawking and John Wheeler were unfortunately no longer there to attend the event with us, but were present several of the other pioneers of the physical black holes like Nobel Prizes in Physics Kip Thorne and Roger Penrose.

Jean-Pierre Luminet had explained in detail, in French and in English on the blog that Futura has made available to it, the origin and characteristics of the images of black holes surrounded by a accretion disk with a hot plasma that one would expect to see. He also traced the history of theastrophysics relativistic about it.

But here is a joint press release from European Southern Observatory (ESO) and theEvent Horizon Telescope (EHT) has just announced that on May 12, 2022 there will be an online conference, at 3:00 p.m. in France, which will report new results and precisely about the Milky Way!

The event will be worldwide.

The conference will be broadcast online on the ESO website and on the ESO YouTube channel. Simultaneous press conferences will be held around the world, including Washington DC, Santiago de Chile, Mexico City, Tokyo and Taipei.
