Tuning in mate, haven't been following this... let's hope it's not some damp squib announcement.

The screen in the background says "unveiling the first ever image of a black hole" ... promising.

"...The history of science will be divided into the time before the image and the time after the image..."

OK, with a prelude like that I can with a pretty safe margin say that I'm going to be underwhelmed :lol:

First ever black hole image released

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy.

It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster".

The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world.

Details have been published today in Astrophysical Journal Letters.

Prof Heino Falcke, of Radboud University in the Netherlands, who proposed the experiment, told BBC News that the black hole was found in a galaxy called M87.

"What we see is larger than the size of our entire Solar System," he said.

"It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exist. It is an absolute monster, the heavyweight champion of black holes in the Universe."

The image shows a intensely bright "ring of fire", as Prof Falcke describes it, surrounding a perfectly circular dark hole. The bright halo is caused by superheated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined - which is why it can be seen at such distance from Earth.

The edge of the dark circle at the centre is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull, not even light can escape.

This Hubble Space Telescope photograph shows the jet of matter ejected from M87 at nearly the speed of light, as it stretches 1.5 kpc (5 kly) from the galactic core



Supermassive black hole

The core contains a supermassive black hole of billions of times the Sun's mass: estimates have ranged from (3.5 ± 0.8) × 109 M☉ to (6.6 ± 0.4) × 109 M☉, with a measurement of 7.22+0.34
−0.40×109 M☉ in 2016. This mass is one of the highest known for such an object. A rotating disk of ionized gas surrounds the black hole, and is roughly perpendicular to the relativistic jet. The disk rotates at velocities of up to roughly 1,000 km/s, and spans a maximum diameter of 0.12 parsecs (0.39 light-years). Gas accretes onto the black hole at an estimated rate of one solar mass every ten years (about 90 earth masses per day).

Observation suggests that the black hole may be displaced from the galactic center by about seven parsecs (23 light-years). The displacement is in the opposite direction of the one-sided jet, which may indicate that the black hole was accelerated away by the jet. Another possibility is that the change in location occurred during the merger of two supermassive black holes. A 2011 study did not find any statistically significant displacement.

Uhhhh..... I just heard them say that the black hole doesn't have a name except for a designation number. I feel an internet naming contest coming up. Dips on Holely McHoleFace

Announcement about the imaging of a black hole in about 30 minutes from now

Live stream: https://www.eso.org/public/live/

Site: https://eventhorizontelescope.org/

Explanation:

They are seeing the event horizon, not the black hole itself. They come across as a bunch of self-congratulatory douchebags, in my opinion. This is not some life-changing announcement, as the one guy suggests. It is a fucking recreation of an image that requires a computer to make it visible, aka a simulation. Fuck these people.
