Astronomers have identified 27 potential new circumbinary planets -- worlds that orbit two stars, like Star Wars' Tatooine. "To date, only about 18 circumbinary planets ... had been identified in the universe," reports the Guardian. "More than 6,000 planets have been discovered that orbit single stars, like Earth does around the sun." The Guardian reports: In a timely publication for May 4, also known as Star Wars Day, scientists have identified nearly 30 more candidate planets, whose distances range from 650 to 18,000 light years away from Earth. [...] More than half of the stars in the universe exist in binary or multiple star systems. The researchers instead used a method known as "apsidal precession," searching for a wobble between stars that orbit around and eclipse each other.

"If we monitor the exact timing of these eclipses ... that can tell us that there's something else going on in the system," said Margo Thornton, the study's lead author and a PhD candidate at UNSW. After eliminating other factors such as the rotation and gravitational pull of the two stars, the team identified 36 star systems out of 1,590 whose behavior could only be explained by a third body. For "27 of those objects, it is possible that they are planet mass," Thornton said.

More research into their spectra -- the light they emit -- was needed to formally confirm them as circumbinary planets, she said. "It's just a matter of: what is the mass of it? Is it a planet? Is it a brown dwarf? Is it a star?" The team discovered the potential planets -- which likely range from Neptune-sized to ten times heavier than Jupiter -- using data from Nasa's Transiting Exoplanet Survey Satellite, a planet-hunting space telescope that launched in 2018. The research was published in the Monthly Notices of the Royal Astronomical Society.

An anonymous reader quotes a report from Ars Technica: In a makeshift demonstration kitchen in Concord, California, cooking oil splatters in and around a frying pan, which catches fire on an unattended gas stove. Within moments, a smoke detector wails. But in this demonstration, something less common happens: An AI-driven sensor activates and wall emitters blast infrasound waves toward the source of the fire in an attempt to put it out. The science of acoustic fire suppression, which has long been known and documented in scientific literature and the press, works by vibrating oxygen molecules away from a fuel source, depriving the fire of a critical component needed for combustion. Indeed, after just a few seconds of infrasound, the tiny kitchen blaze goes out.

"We were able to not just point-and-shoot like a fire extinguisher; we figured out how to run it through ducting and distribute it like a sprinkler system," said Geoff Bruder, co-founder and CEO of Sonic Fire Tech, during the presentation. The company's goal is to replace sprinklers, which are effective at stopping fires but can also do significant water damage to a property. Sonic Fire Tech appears to be the first company trying to commercialize the science of acoustic fire suppression. Its executives have already been touring Southern California; Wednesday's event was the first in the northern half of the state.

The company aims to make this infrasound technique mainstream in both commercial (for instance, a data center, where sprinklers would damage electronics) and in-home installations, given that sprinklers are already required in all new California homes built in 2011 and later. Sonic Fire Tech also hopes to produce a backpack-based system that could be worn by wildland firefighters headed out into the field. "We are making meaningful technological improvements on a monthly basis," Stefan Pollack, a company spokesperson, emailed Ars after the event. But two experts who spoke with Ars raised serious questions about the potential for this technology to supplant traditional sprinklers in a home. They are even more skeptical as to whether the technique can be effective in an uncontrolled wildfire situation, where flames can grow very quickly. Experts are concerned that infrasound may knock down small flames but does not cool hot surfaces or wet fuel like sprinklers do, which raises the risk of re-ignition, smoldering fires, hidden fires, or blocked fires. Sonic Fire Tech has claimed third-party validation and possible NFPA 13D equivalency, but it has not publicly released full testing details.

Fire officials and outside observers also want more information about reliability, maintenance, calibration, and how system failures would be detected and communicated.

In the late 12th century, a nobleman named Count Gerard van Loon commissioned an abbey to serve as his final resting place. Over the next few decades, amid plenty of political tumult, Herkenrode Abbey in Hasselt, Belgium, was converted to the first Cistercian convent for women. It was a site of pilgrimage from the 13th to the 15th centuries, and despite regional wars and economic uncertainty, it stayed the course. During the 16th century, it experienced its heyday thanks to the patronage of a figure named Prince Bishop Evrard van der Marck, seeing the addition of a Gothic church that brimmed with beautiful stained glass windows, textiles, paintings, and more.

The Eighty Years’ War paused Herkenrode’s prosperity, and once things stabilized again politically, the abbey experienced several decades of good fortune, although much of this wealth was spent on the abbesses’ own acquisitions of property and art in a show of their prestige. But the paradigm-shifting Liège Revolution, which coincided with the French Revolution, brought all of this crashing to a halt by 1796. The abbey complex was promptly sold and dismantled.

Throughout the 19th and 20th centuries, Heckenrode went through many other uses, including factories and even a series of private homes, before it was again acquired by a religious organization in the 1970s. While the original 16th-century abbey church no longer exists due to a devastating fire in 1826, the site remains one of the region’s most culturally significant. And Herita has been working to restore it. As part of a phased regeneration of the landmark and its park, an ethereal, life-size sculpture of the abbey titled CLAUSURA by Gijs Van Vaerenbergh has risen from the building’s original footprint.

The studio, founded by Belgian designers Pieterjan Gijs and Arnout Van Vaerenbergh, conceived of CLAUSURA as “an artistic vision for the vanished heart of Herkenrode.” True to scale, the structure is made of slender steel rods that rise from the ground in an airy framework. The installation revolves around the idea of memory and sensation: rather than rebuilding the abbey to try to mirror what it may have looked like hundreds of years ago, the work nods to its past with an airy elegance.

“The new volumes are transparent, allowing their silhouettes to blend seamlessly with the landscape in the background,” says a statement. “The intervention balances between reconstruction and abstraction, as the original structures are evoked through a refined play of suggestion. Iconic details such as windows, vaults, and towers enhance the sense of recognisability, although at times, these elements dissolve back into a chaos of lines.”

Gijs Van Vaerenbergh is known for its architectural interventions, often utilizing steel, stone, wood, and a wide range of other building materials to re-envision spaces as structural sculptures. “What unites their diverse output is a sustained focus on how space is experienced—visually, bodily and temporally,” a statement says.

CLAUSURA is being constructed in three phases. The first, which is also the most ambitious, is slated to open to the public on June 18. Visitors will be able to walk and reflect amid the installation. See more on Gijs Van Vaerenbergh’s Instagram, and learn about the restoration progress and how to visit on Herita’s website.
