Astronomers start making an "innovative" black hole ad

Astronomers working on a global network of space observatories will make an "innovative" announcement on April 10, according to the European Southern Observatory. The first image of a black hole, this may be one of the greatest scientific discoveries of the year ̵

1; for the first time, people can "see" the black hole in the center of the Milky Way galaxy or in one of our close cosmic neighbors, Messiah 87. [19659004] Of course, black holes are invisible space vampires. Their enormous gravity sucks any surrounding matter – including light – that falls within their reach. And once something comes, it will never escape. It makes it absolutely impossible to see a black hole right now.

However, at the very edge of the powerful gravity of the black hole lie the "horizon of events." The material accumulates in this area and accelerates around the black hole at such a rate that it emits high energy radiation – the things we can see. Over the last 13 years, the Event Horizon telescope, which is actually a network of radio observatories across the planet, is trying to mimic two black holes: Sagittarius A * in the center of the Milky Way, and the black hole in the center of Messier 87, the nearby elliptical galaxy.

Observatories all over the world focus on black hole locations and individually capture radio signals emanating from the events horizon. The data they capture is digitized and stored on hard drives that are physically sent to the participating institutions for analysis. Since every telescope in the world is synchronized with an incredibly precise clock, the data can be linked, stitched together and eventually – and this is the holy grail – to create an image of the horizon of black hole events. The latest data collection happened two years ago, in April 2017. During this time, astronomers gathered the results of the manipulation and now many people suspect that the April 10 message will give us the first real look of a black hole.

This is not certain, but given that media counseling implies a "revolutionary result" that will be broadcasted simultaneously in six different locations and in four different languages ​​around the world, there is reason to be excited.

at 6am PT, April 10th. Whatever the result, CNET will cover it.
