Astronomers have classified planetary systems into four distinct categories, based on the sizes and arrangements of their planets. As it turns out, the architecture of our own solar system is the rarest kind.

Decades of telescopes dedicated to the hunt for worlds around stars other than our own Sun have yielded more than 5,300 of these exoplanets so far, contained in 3,910 planetary systems. With that much data astronomers have been able to classify these planets into different groups based on their characteristics – there are rocky planets, gas giants, Super-Earths, mini-Neptunes and water worlds, among others.

But can planetary systems themselves be classified in similar ways? And if so, how does our own solar system stack up on a cosmic scale? Answering those questions was the goal of a new study by scientists in Switzerland, who examined data from all 853 systems known to contain multiple planets.

(Filmed as: Blade Runner) by Philip K. Dick full audiobook. With cast and corresponding animated imagery.

Bounty hunter Rick Deckard wakes up to a world devastated by nuclear war, where humans care for animals to prevent the mass extinction of several species, where androids are colonial slaves who kill their masters and flee to hide on Earth.
Deckard’s boss Harry Bryant tells him that Dave Holden, another bounty hunter, was hurt while hunting fugitive androids, and now Deckard has to finish the job.
The catch? The androids are Nexus-6 models, the most intelligent, advanced androids ever created.

For centuries, the town of Carrara’s prosperity has depended on artists. Its famed Tuscan marble quarries supplied artists like Michelangelo, Canova and Bernini with the finest material for their sculptures. Today, robots are being used to create modern-day works. Chris Livesay has more.

Security researchers are seeing threat actors switching to a new and open-source command and control (C2) framework known as Havoc as an alternative to paid options such as Cobalt Strike and Brute Ratel.

Among its most interesting capabilities, Havoc is cross-platform and it bypasses Microsoft Defender on up-to-date Windows 11 devices using sleep obfuscation, return address stack spoofing, and indirect syscalls.

Like other exploitation kits, Havoc includes a wide variety of modules allowing pen testers (and hackers) to perform various tasks on exploited devices, including executing commands, managing processes, downloading additional payloads, manipulating Windows tokens, and executing shellcode.

It’s the twenty-fifth century, and advances in technology have redefined life itself. A person’s consciousness can now be stored in the brain and downloaded into a new body (or “sleeve”), making death nothing more than a minor blip on a screen. Onetime U.N. Envoy Takeshi Kovacs has been killed before, but his last death was particularly painful. Resleeved into a body in Bay City (formerly San Francisco), Kovacs is thrown into the dark heart of a shady, far-reaching conspiracy that is vicious even by the standards of a society that treats existence as something that can be bought and sold. For Kovacs, the shell that blew a hole in his chest was only the beginning.

Over 50 percent of high-mass stars reside in multiple star systems. But due to their complex orbital interactions, physicists have a difficult time understanding just how stable and long-lived these systems are. Recently a team of astronomers applied machine learning techniques to simulations of multiple star systems and found a new way that stars in such systems can arrange themselves.

Classical mechanics has a notorious problem known as the three-body problem. While Newton’s laws of gravity can easily handle calculations of the forces between two objects and their subsequent evolution, there is no known analytic solution when you include a third massive object. In response to that problem, physicists over the centuries have developed various approximation schemes to study these kinds of systems, concluding that the vast majority of possible three-object arrangements are unstable.

But it turns out that there are a lot of multiple-star systems out there in the galaxy. Indeed, over half of all massive stars belong to at least a binary pair, and many of them belong to triple or quadruple star systems. Obviously, the systems last a long time. Otherwise, they would have flung themselves apart a long time ago before we had a chance to observe them. But because of the limitations of our tools, we have difficulty assessing how these systems organize themselves and what stable orbit options exist.
