Supercomputers Crack the Code of Super-Diamond Synthesis

Posted by in categories: particle physics, space, supercomputing

Researchers are on a quest to synthesize BC8, a carbon structure predicted to be tougher than diamond, using insights from advanced simulations and experimental efforts. This material, theoretically prevalent in the extreme pressures of exoplanets, remains a scientific mystery with promising applications in materials science.

Diamond is the strongest material known. However, another form of carbon has been predicted to be even tougher than diamond. The challenge is how to create it on Earth.

The eight-atom body-centered cubic (BC8) crystal is a distinct carbon phase: not diamond, but very similar. BC8 is predicted to be a stronger material, exhibiting a 30% greater resistance to compression than diamond. It is believed to be found in the center of carbon-rich exoplanets. If BC8 could be recovered under ambient conditions, it could be classified as a super-diamond.

Ultraviolet Radiation from Massive Stars Shapes Planetary Systems

Posted by in categories: materials, space

Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.

Radiation From Massive Stars — 100,000 Times More Luminous Than the Sun — Shapes Planetary Systems

Posted by in category: space

An international team used the James Webb Space Telescope to study a protoplanetary disc in the Orion Nebula, revealing how massive stars significantly influence the formation of planetary systems. They discovered that intense ultraviolet radiation from these stars can prevent the formation of Jupiter-like planets in systems like d203-506, providing new insights into the complexities of how planetary systems develop.

How do planetary systems such as the Solar System form? To find out, CNRS scientists taking part in an international research team[1] studied a stellar nursery, the Orion Nebula, using the James Webb Space Telescope.[2] By observing a protoplanetary disc named d203-506, they have discovered the key role played by massive stars in the formation of such nascent planetary systems.[3].

“Semiparametric Token-Sequence Co-Supervision”

We introduce semiparametric token-sequence co-supervision, which trains LM by simultaneously leveraging supervision from a parametric token and a nonparametric sequence embedding space.

Astronomers Puzzled by Cosmic Megastructure So Large It Shouldn’t Exist

Posted by in category: space

Lurking some nine billion light years away from Earth is what appears to be a so-called cosmic megastructure in the shape of an enormous ring. It’s so large that its existence should be impossible, according to new research reported on by The Guardian, challenging a fundamental assumption of our understanding of the Universe.

Known as the “Big Ring,” the structure spans an astonishing 1.3 billion light years in diameter — a significant portion of the observable Universe’s estimated size of 94 billion light years. By contrast, the largest known galaxy is a “mere” 16 million light years across. If it were visible in the night sky to the naked eye, the Big Ring would be equal in diameter to fifteen full moons. Succinctly put: it’s unfathomably huge.

The unpublished findings, presented at the annual meeting of the American Astronomical Society on Thursday, add to a growing list of inexplicably large structures that remain confounding — if not controversial — to scientists.
