Last April, the Event Horizon Telescope (EHT) project unveiled the first-ever imagery of a black hole , laying bare the supermassive monster at the heart of the galaxy M87. The landmark photos have opened new doors, allowing scientists to probe exotic space-time realms like never before.
And that probing may go much deeper still in the not-too-distant future. The most prominent feature in the EHT imagery, a bright but unresolved ring around M87's supermassive black hole , likely contains a thin "photon ring" that is composed of an infinite sequence of subrings, a new study reports.
Not to change the topic here:
I've seen things you people wouldn't believe.
Astronomers have discovered the universe's most powerful winds: driven by supermassive black holes, they ripple across interstellar space bulldozing through material in galaxies, and are known as quasar tsunamis, we're told.
"No other phenomena carries more mechanical energy," said Nahum Arav, first author of a study into the winds, and a physics professor at the Virginia Polytechnic Institute and State University (Virginia Tech) in the US.
"The amount of mechanical energy that these outflows carry is up to several hundreds of times higher than the luminosity of the entire Milky Way galaxy."
The Supermassive Black Hole at The Centre of Our Galaxy Is Becoming More Active
Sagittarius A*, the supermassive black hole at the centre of the Milky Way, isn't exactly rowdy. It's not classified as an active galactic nucleus - one of those galactic cores that glow exceedingly brightly as they feast on copious amounts of material from the surrounding space.
However, the brightness of our galaxy's centre does fluctuate a little across the electromagnetic spectrum on a daily basis. Astronomers have now confirmed that, over the last few years, Sgr A*'s most energetic X-ray flares have been increasing.

In April 2019, astronomers released an amazing image of a supermassive black hole in the center of the galaxy M87 . It was the highest resolution image of a black hole ever taken, and showed an eerily glowing fuzzy ring of material with a dark spot in the center. That wasn't the black hole itself, but in a sense its shadow ; the larger volume of space around it where no orbit is stable, and even light itself eventually falls into the infinitely deep pit.

As cool as that image is, it's fuzzy for two reasons. One is that despite the Event Horizon Telescope (as the array that made the observations is called) combining the powers of telescopes literally all around the world, the resolution just isn't high enough to see many details — from 55 million light years away, even a big black hole looks pretty small. The other is that the exposure times were long, so any features like blobs of gas swirling around the black hole got blurred out.
This may worth something:
Scientists create simulated high-resolution image of black hole 55 million light years from Earth
Researchers analyzing the first-ever image taken of a black hole taken by a powerful telescope last year announced this week that they have analyzed new data that sheds light on its mass, rotation, and shape.
Last April, the Event Horizon Telescope (EHT) team at Harvard-Smithsonian Center for Astrophysics was able to capture the silhouette of the super massive black hole that lies at the center of Messier 87 (M87), a galaxy that lies 55 million light years away.
AFL clubs urged to unify amidst black hole | 7NEWS.com.au
West Coast coach Adam Simpson is calling on the entire league to unite and do whatever it takes to survive as the AFL faces the biggest financial crisis in its long history.
The AFL season has been put on hold until at least May 31 in response to the coronavirus pandemic and there's no guarantees the campaign will be able to resume again this year.
The financial hole left by the crisis will hit the AFL hard and there are fears some clubs will struggle to survive.
Super Rugby 2020: Australian rugby prepares for cost-cutting, and to go to governments for
As the NRL and AFL announced drastic measures, such as a head office shutdown and mass stand-downs across clubs after the suspension of both competitions, Rugby Australia, the Super Rugby sides and the players' union were locked in talks on Monday over the short to medium term survival of the game.

RA boss Raelene Castle faced fires on several fronts. The game's last hope of keeping meaningful revenue flowing was extinguished with the suspension of plans for a new domestic professional competition, while news the Tokyo Olympics would be postponed added further complexity.
Call of Duty: Warzone player encounters black hole visual glitch | Dot Esports
Call of Duty: Warzone players have experienced a variety of bugs and glitches since the game’s release earlier this month. Most recently, one player experienced a major visual glitch that completely obscured their vision in-game and caused them to die.
The player claims this glitch happens almost every game for them, and other users confirmed they have also experienced the visual bug. Some players have experienced it only once or twice, so it might be more common for specific players. The original player was playing on PC when the issue occurred, so it might be more of a problem on that platform.
