Astronomers are searching the cosmic lost-and-found for one of the biggest, baddest black holes thought to exist. So far they haven't found it.
In the past few decades, it has become part of astronomical lore, if not quite a law, that at the center of every luminous city of light, called a galaxy, lurks something like a hungry Beelzebub, a giant black hole into which the equivalent of millions or even billions of suns have disappeared. The bigger the galaxy, the more massive the black hole at its center.
In case you are keeping track:

Nuclear fusion, solar fuels , floating offshore nuclear plants, and microwave beaming . These are some of the esoteric and rather outrageous renewable energy ideas that scientists have proposed to help break our over-reliance on fossil fuels.
And now you can add harvesting energy from black holes to that list as we kick-start missions to colonize Mars and other planets.
Griff shares new dark pop anthem 'Black Hole' | NME
Griff has dropped a new single, ‘Black Hole’, marking her first new release of the year.
The release was coupled with a lyric video, featuring grainy footage of the singer encapsulated within a pin-hole camera shot.

"I actually love how melodramatic it is, as there's obviously not ‘a big black hole where my heart used to be'”, Griff added.
“But the melodrama of the lyrics – over a really interesting beat – keeps the song fun, and not too serious."
The most ancient supermassive black hole is bafflingly big | Science News
This active supermassive black hole, or quasar, boasts a mass of 1.6 billion suns and lies at the heart of a galaxy more than 13 billion light-years from Earth. The quasar, dubbed J0313-1806, dates back to when the universe was just 670 million years old, or about 5 percent of the universe's current age. That makes J0313-1806 two times heavier and 20 million years older than the last record-holder for earliest known black hole ( SN: 12/6/17 ).
Finding such a huge supermassive black hole so early in the universe's history challenges astronomers' understanding of how these cosmic beasts first formed, researchers reported January 12 at a virtual meeting of the American Astronomical Society and in a paper posted at arXiv.org on January 8.
This may worth something:
"Old Faithful" cosmic eruption shows black hole ripping at star
You’ve heard of Old Faithful, the Yellowstone National Park geyser that erupts every hour or two, a geological phenomenon on a nearly predictable schedule.
Now, an international group of scientists who study space have discovered an astronomical “Old Faithful” – an eruption of light flashing about once every 114 days on a nearly predictable schedule. The researchers believe it is a tidal disruption event, a phenomenon that happens when a star gets so close to a black hole that the black hole “rips” away pieces of the star, causing the flare.
University of Arizona researchers spot black hole beacon from when universe was young | Local
An illustration shows a distant galaxy with an active quasar at its center. A team from the University of Arizona's Steward Observatory recently discovered the earliest and most distant quasar known to science.
A team from the University of Arizona's Steward Observatory has discovered the earliest and most distant quasar known to science, edging out the previous record-holder found three years ago by some of the same astronomers.
The new quasar is 13.03 billion light-years from Earth and dates to 670 million years after the Big Bang, when the universe was just 5% of its current age.
50 Years Ago, C.V. Vishveshwara Built On Einstein's Gravitational Wave Theory : NPR
For a scientist, few things are sweeter than data from an experiment that confirms a theoretical prediction.
C.V. Vishveshwara was one of the lucky ones. He got to enjoy what Einstein had missed, and the detection of gravitational waves verified a theoretical prediction that Vishveshwara himself had made nearly half a century earlier.
In 1970, Vishveshwara, known to his friends as Vishu, was a physics graduate student at the University of Maryland.
Could We Extract Energy From a Black Hole? Scientists Propose a Wild New Plan
For decades, scientists have wrestled with a complex mystery of physics: Could the immense amounts of energy theoretically produced by rotating black holes ever be tapped by human hands?
If future societies were somehow able to pull off this magnificent feat, the power supply of far-off galactic civilisations would seemingly be assured - and now scientists have a new explanation for how such an exotic extraction might one day be possible.
"Black holes are commonly surrounded by a hot 'soup' of plasma particles that carry a magnetic field," explains astrophysicist Luca Comisso from Columbia University.
