At the heart of our galaxy lies a sleeping giant: A supermassive black hole which is 4 million times the mass of our sun. It’s believed that most other galaxies have such an enormous black hole at their center, too. But now, astronomers have discovered something unexpected about these monstrous black holes. It may be possible for planets to orbit around them.
It was generally thought that planets only formed from protoplanetary disks of dense dust and gas which are found around stars. The new research from the National Astronomical Observatory of Japan suggests that planets could also form in the doughnut-shaped cloud of dust and gas, called a torus, which is found around a supermassive black hole.
This may worth something:
How Large Can A Planet Be? - Universe Today
Jupiter is the largest planet in the solar system. In terms of mass, Jupiter towers over the other planets. If you were to gather all the other planets together into a single mass, Jupiter would still be 2.5 times more massive. It is hard to understate just how huge Jupiter is. But as we've discovered thousands of exoplanets in recent decades, it raises an interesting question about how Jupiter compares. Put another way, just how large can a planet be?
What Does Pluto Represent in Astrology? - Pluto Planet Zodiac Meaning
When we look at our charts and cosmic transits, the dwarf planet Pluto represents transformation . While Pluto may be small in size (it’s approximately half the width of the whole United States *the more you know*), it packs a bigger punch than most other planets in astrology.
Its energy is extremely potent and powerful: Pluto represents the underbelly of emotions, what lies beneath the surface, and the subconscious mind. All the parts of ourselves that we do not share freely with the outside world. (Casual.) It destroys weak foundations, only to rebuild stronger and more resilient than before. (Again, totes chill.) Pluto is also the natural investigator and BS detector of the zodiac—it’s hard to get anything past this intense planet.

Eco-Visionaries: Confronting a Planet in a State of Emergency review – speculative and oblique |
Elsewhere, you can see the invisible pollutants in Madrid rendered as coloured clouds. There is The Breast Milk of the Volcano , a work by Unknown Fields about the astonishing Salar de Uyuni in Bolivia, a vast white salt flat that is part of the lithium triangle, the area containing more than half the world's known supply of an element extremely useful in long-lasting and high-performing batteries. The film draws attention to the mythic importance of the area to its indigenous people.
You're encouraged to reflect on the fact that jellyfish have existed for hundreds of millions of years and could continue for hundreds more, especially as they are currently benefiting from global warming. Homo sapiens , whose survival is so much more demanding of resources, would be lucky to last a fraction of that time. It is another work that, while clever and engaging, is more likely to provoke mild reflection than a call to arms.
Escape from Planet Trash review – a Christmas B-musical misadventure | Stage | The Guardian
There is a certain, if limited, absurd pleasure to the show's bizarre unpredictability. Johnson leans valiantly into panto humour, wading through the crap for camp meta-winks and dirty jokes, and Cumming tries to lift the energy with his gymnastic facial expressions, while Clancy Flynn's celestial lighting illuminates how good the show could be.
But the majority of this production is severely starved of oxygen. Songs are endured rather than enjoyed, awkward silences suggest every third line is forgotten – this isn't helped by uneven sound levels – and the cast deliver their dialogue so devoid of energy it's as if they'd rather be elsewhere. After an interpretive dance battle with giant turkeys and an obligatory 17th turn of the rotating stage to remind us we're in space, I can't help but feel the same.
COP25 UN climate talks to focus on carbon credits — Quartz
Delegates from around the world will gather Monday in Madrid for the start of a week of climate change summitry. This follows a major UN report showing that the goal of holding climate change at 1.5°C above pre-industrial average temperatures—the threshold at which climate change becomes catastrophic—is nearly impossible.
The planet is on track for 3.2°C of warming above pre-industrial levels by 2100. To stay below the 1.5°C threshold, global emissions would need to be cut by more than 7% every year between 2020 and 2030. That means emissions in 2030 would have to be 55% lower than they were in 2018. Put another way, "peak emissions" can't come soon enough.
