Earlier this year, researchers revealed the discovery of an extraordinarily compact “one-of-a-kind” system of three stars. A partnership between two young researchers at the Niels Bohr Institute at the University of Copenhagen is currently focusing on how this unusual combination of a binary set of stars and a revolving larger star can form.

The star system is made up of a binary set of stars, two stars that orbit each other, and one more massive star that orbits the binary.

“As far as we know, it is the first of its kind ever detected”, Alejandro Vigna-Gomez says. “We know of many tertiary star systems (three star systems), but they are typically significantly less massive. The massive stars in this triple are very close together – it is a compact system. The orbital period of the binary (~1 d) is the same as that of the rotation of Earth (1 day). The combined mass of the two of them is twelve times the mass of our Sun – so rather big stars. The tertiary star is approximately 16 times the mass of our Sun, so even bigger! The inner orbit is circular in shape with close to six revolutions of the tertiary star around the binary per year. Pretty fast, when you consider the size of them – unsurprisingly, the system is very luminous, so at first they were detected as a stellar binary”.

In this video I explain how the argument that the universe is finetuned for life works, why it’s wrong, how the mistake happens, and what that means for the existence of god and the multiverse.

The UK is truly a world leader in offshore wind and the completion of Hornsea Two is a tremendous milestone for the offshore wind industry.

This week, the massive Hornsea 2 project became fully operational off the coast of the UK.

The findings could revolutionize how we study potential collisions.

Asteroids pass by our planet all the time and even sometimes land here, causing much devastation. Understanding how often these kinds of impacts happened in the past and how they influenced the environment both then and today is crucial to protecting Earth.

Now, new research published by the Estonian Research Council on Friday has shown that analyzing bodies of organisms killed by an impact of asteroids can teach us how much damage occurs at the spot of such a cosmic collision.

The latest study focused on serotonin receptors in the brain, crucial for memory, fear, and attentiveness.

Scientists have discovered a new type of synapse hiding in the brains of mice. Researchers at HHMI’s Janelia Research Campus.

“This special synapse represents a way to change what is being transcribed or made in the nucleus, and that changes whole programs,” said David Clapham, Janelia’s senior group leader.

Is AI replacing artists or simply complementing their work?

Artists participating in the Colorado State Fair’s annual art competition were furious after the president of the Colorado-based tabletop gaming company Incarnate Games, Jason Allen, won the first prize in the Digital Art Category, according to a report published by CNBCTV18.com on Saturday.

Aviation is responsible for around five percent of human-induced climate change.

Commercial aviation has become a cornerstone of our economy and society. It allows us to rapidly transport goods and people across the globe, facilitates over a third of all global trade by value, and supports 87.7 million jobs worldwide. However, the 80-tonne flying machines we see hurtling through our skies at near supersonic speeds also carry some serious environmental baggage.

My team’s recent review paper highlights some promising solutions the aviation industry could put in place now to reduce the harm flying does to our planet. Simply changing the routes we fly could hold the key to drastic reductions in climate impact.

Nvidia is caught up in the new sanctions the U.S. is imposing on China. Rita reports the company said it will not be able to export two of its AI chips to China, its second-largest market. That will likely cost Nvidia some $400 million in lost sales for this third quarter and interrupt some production that happens in China. get a roundup of TechCrunch’s biggest and most important stories delivered to your inbox every day at 3 p.m. PDT, subscribe here.

Happy Friday! For those of you excited to see us in your inbox for your daily dose of tech news, unfortunately, you will have to wait until Tuesday to hear from us again because Monday is Labor Day in the U.S. We will be out grilling, wearing white for the last time this year and snoozing in hammocks.
