The astronomers are going to make an innovative announcement; for a black hole

Astronomers working across a global network of cosmic observatories will make an "innovative" announcement on April 10, according to the Southern European Observatory.

Given that the Horizon Telescope Event is on a mission to capture the first image of one black hole, this could be one of the biggest scientific discoveries of the year – people may, for the first time, be "able to see" a black hole in the center of the galaxy. Milky Way or one of our near cosmic neighbor, Messier 87.

Of course, there are black holes invisible space vampires. Their immense gravity sucks any issue around it – including light – which comes within their grip. And once something falls, he can never escape. That makes it really impossible see black hole at the moment.

However, on the edges of a black hole there is a powerful gravity lying on the horizon "event". Material builds up in this region and accelerates around the black hole at a speed so that it emits high energy radiation – the things we can see. Over the past 13 years, the Horizon Telescope Event (a network of radio observatories across the planet in fact) has been trying to visualize two black holes: Sagittarius A *, in the center of the Milky Way, and; The black hole in the middle Messier 87, an elliptical galaxy nearby.

The observatories around the world focus on the black hole locations and hold the radio signals dropped by the event's individual horizon. The data they hold is digitized and stored on hard drives, which are physically flown to organizations taking part in their analysis. As each telescope across the world is all matched with a highly accurate clock, it can correlate, stitched the data with each other and eventually – and this is the holy grail – produces an image of the black hole event event.

The last collection of data occurred two years ago, in April 2017. During that time, astronomers have been collecting the results from the run – and many suspect that the t announcement on April 10 gives us a real insight into black hole.

There is no certainty, but given that the media advises an "innovative outcome" that will be streamed simultaneously in six different locations and four different languages ​​around the world, there is reason to be excited.

The official announcement will start at 6 am PT, April 10. Whatever the outcome, CNET will be included.
