Astronomers around the world are about to make an innovative black hole ad


The European Southern Observatory has just revealed that there will be a big announcement next week. Yes, we know how that sounds – but, as far as we can tell, it looks like the world is about to finally see the first photo of the event horizon of a black hole.

Of course we will not be sure until the press event, which we will cover live on our site. But here's a huge tip: according to the advance statement, the researchers will be discussing the "first result of the Event Horizon Telescope."

For years, the Event Horizon Telescope has been looking into the heart of the Milky Way, trying to get a picture of the location of Sagittarius A *, the supermassive black hole in our galaxy.

It's not an easy feat: the black holes themselves are literally invisible – they absorb all electromagnetic radiation, which means none of our telescopes – radio, X-ray, gamma rays – can detect them.

That's why we never saw one.

But seeing the event horizon – the point outside a black hole in which light can no longer reach escape velocity – is theoretically possible, though not easy. Spacetime around a black hole is strange; In addition, Sgr A * is wrapped in a thick cloud of dust and gas.

Do not let this stop dedicated scientists. Telescopes around the world turned their combined strength into the task, generating so much data that the only way to carry everything was on hard drives shipped on airplanes. And then the researchers had to sort and analyze these data.

Now something is finally ready. On April 10, 2019, at 15:00 CEST (13:00 UTC, 9:00 EST), the European Commission, the European Research Council and the Event Horizon Telescope (EHT) project will present the results they describe as " innovators ".

As they note, "because of the importance of this result, we encourage satellite events in different ESO Member States and beyond."

AAAAAH We can wait long.

The event will be broadcast on YouTube and there is a link here. Pop in your favorites. We'll also be blogging live, so tune in to the day if you want to share our excitement.

This is going to be historical.
