Astronomers have discovered the existence of a supermassive black hole that looks to be the oldest and most distant of its kind we've ever encountered – and it just happens to be aiming its bright particle beam directly at Earth.
The newly found supermassive black hole – called PSO J030947.49+271757.31 – is the most distant blazar ever observed, researchers say. That conclusion is based on the wavelength signature of the object's redshift , a phenomenon scientists can use to measure the distance of light-emitting sources in space.
This may worth something:
An Ancient Black Hole as Heavy as a Billion Suns Is Pointed Right At Us - VICE
Scientists have discovered the most ancient and distant "blazar," a galaxy with a supermassive black hole that spews out mind-boggling amounts of light, at the edge of space and time. The object is roughly 13 billion light years away, but scientists were able to detect it because it is so "radio-loud," meaning it is incredibly luminous even from afar.
A team led by Silvia Belladitta, a graduate student at the University of Insubria in Italy, announced the discovery of the blazar on Friday in the journal Astronomy & Astrophysics . Named PSO J030947.49+271757.3 (or PSO J0309+27 for short), it is the first known blazar at such a high "redshift," which is a scale that measures the distance of luminous objects based on the distorted color of their light.
Black holes and neutron stars may collide unseen in dense star clusters | Space
Astronomers have yet to witness a collision between a black hole and a neutron star, but they predict that such a smashup would unleash huge amounts of energy but, unexpectedly, might not generate any detectable light, a new study finds.
These findings reveal how key details about mergers between black holes and neutron stars, such as the amount of detectable light and the mass of the colliding objects, can shed light on contributing factors behind the mergers, such as the dynamics that drove these smashups to happen.
A black hole ‘burp’ devastated a distant galaxy cluster – BGR
The black hole that scientists believe sits at the center of the Milky Way galaxy doesn’t cause us much trouble here on Earth. As NASA’s Chandra X-Ray Observatory recently discovered, the same can’t be said for the distant Ophiuchus galaxy cluster, a massive galaxy that is home to a very powerful black hole.

The cluster, which is located around 390 million light-years from Earth, was devastated when its beefy black hole caused a colossal explosion. The blast was so mighty that it actually blew a hole straight through the cluster, destroying countless stars and, presumably, planets, moons, and other objects in the process.

Black Ravioli Black Hole Modules - More Than Grounding Boxes | StereoNET United Kingdom
Following on from the company's original equipment support pads, Black Ravioli now launch their Black Hole system modules.
Black Ravioli products have been developed by Sailforth Ltd in Scotland and, they say, are embodied with an ethos gained from the nuclear operation and radio broadcast engineering experience of its chief designer.

The Black Hole modules, says the company, work by removing spurious energy from music servers, streamers, active speakers and almost any electronic device that interfaces a music system. Black Ravioli states on its website:
A Black Hole Collision Really Makes Waves – Now. Powered by Northrop Grumman
When two black holes with a combined mass of more than 50 suns crash headlong into each other, you might expect it to shake things up — and you would be right. A black hole collision in a galaxy nearly 2 billion light-years away produced a cosmic jolt so powerful that it was detected in the summer of 2017 by three widely separated observatory instruments on Earth.
Two of the instruments, as the National Scie nce Foundation reports, belong to the Laser Interferometer Gravitational-Wave Observatory, a project funded by the NSF. The two independent LIGO detectors are located in Louisiana and Washington state, while the third detector, called Virgo, is located in Italy.
Record-Breaking Explosion by Black Hole Spotted 390 Million Light Years from Earth |
(NASA) – The biggest explosion seen in the universe has been found. This record-breaking, gargantuan eruption came from a black hole in a distant galaxy cluster hundreds of millions of light years away.
“In some ways, this blast is similar to how the eruption of Mt. St. Helens in 1980 ripped off the top of the mountain,” said Simona Giacintucci of the Naval Research Laboratory in Washington, DC, and lead author of the study. “A key difference is that you could fit fifteen Milky Way galaxies in a row into the crater this eruption punched into the cluster’s hot gas.”
Fix "Fragmented" IT Licensing to Help Plug Council Funding Black Hole
The Local Government Association (LGA) has warned that local authorities are on track to face a funding chasm in England of a stark £6.5 billion by 2025.
Now, in a budget proposal submitted ahead of the Chancellor’s budget on Wednesday, it has called on the government to support techno investment and make regulatory changes that can “help streamline complex services such as licensing.”
The announcement comes as councils have lost £15 billion in central government funding over the past decade of “austerity”.
