Astronomers Prepare to Reveal “Revolutionary” Discovery in the Milky Way Galaxy

On May 12, 2022, astronomers from the European Southern Observatory (ESO) will present the world with new information about our galaxy.
The announcement hasn’t clearly been defined yet, but we can get an idea based on the fact that the results will be those of the Event Horizon Telescope (EHT), which took the first-ever image of a black hole in 2019.

A supermassive black hole is likely to reside at the center of the Milky Way galaxy, which has been the focus of the EHT project for years.

They’ve uncovered something that seems to represent a transcendental level of knowledge.

As scientists hold simultaneous press conferences around the world, the secrets they’re keeping will likely be the next big thing after the historical moment of 2019. It is expected that the announcement will happen on May 12. It will be followed by a YouTube event with six astronomers from around the world at 15:00 CEST (13:00 UTC, 9:00 EST). ‘Extensive audiovisual material will support the press release,” it has been revealed.

If astronomers have succeeded in producing a direct image of Sgr A*’s event horizon, it will be a historic moment that should not be missed.
Because black holes are basically invisible and absorb all electromagnetic energy, they are extremely hard to visualize.

There is only one thing we may see: the event horizon – basically, the outline of the black hole – representing the point where light can no longer escape the gravitational pull of the black hole. Unfortunately, however, it is difficult to study Sgr A* because a cloud of dust and gas obscures it.

According to astronomers who have imaged the black hole’s horizon, it should appear as a shining doughnut. As gas and dust fall into the abyss, extreme radiation is released by the accretion disk around the black hole.

In its press release, ESO promises “something revolutionary”, which matches their wording in announcing the first direct image of a black hole at the center of the M87 galaxy. This gigantic Black Hole has a mass of 6.5 billion times the mass of the Sun. The event horizon of this object has a radius of about 20billionkilometers. Directly photographing it is equivalent to viewing a 1-millimeter-sized object from a distance of 13,000 kilometers (8,000 miles).

We are much closer to Srg A* because it lies at the heart of our own galaxy. It is, however, quite small compared to other black holes, only 4.3 million times the size of the Sun. As a result, it is detectable only since it is closer than M87*. So, a photograph of its event horizon would surely be revolutionary if astronomers were able to capture it. What’s to come in THAT picture should be exciting.
