Scientists find galaxy supercluster as massive as 26 quadrillion suns

Posted by in category: space

The Einasto Supercluster is so vast that it would take a light signal 360 million years to get from one end to the other.

Thermonuclear flames: Astrophysicists use supercomputer to explore exotic stellar phenomena

Posted by in categories: physics, space, supercomputing

Understanding how a thermonuclear flame spreads across the surface of a neutron star—and what that spreading can tell us about the relationship between the neutron star’s mass and its radius—can also reveal a lot about the star’s composition.

Everest-sized ‘Devil comet’ tonight: How to see the once-in-a-lifetime 2024 event

Posted by in category: space

As we speak, the comet 12P/Pons-Brooks (Pons-Brooks, for short) is making its way around the inner region of the Solar System for the first time in more than 70 years – and might soon become visible to the naked eye.

At approximately 30 kilometres (19 miles) across, this giant icy lump is comparable in size to Mount Everest, says astrophysicist Dr Paul Strøm, and is “one of the brightest known periodic comets”

A Halley-type comet, Pons-Brooks completes its journey around the Sun every 71.3 years and was last spotted in our skies in 1954.

Two ancient threads discovered in Milky Way galaxy named Shiva and Shakti

Posted by in categories: chemistry, space

Khyati Malhan of the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany, who spearheaded the research, expressed astonishment at the ability to detect these ancient structures.

“The Milky Way has undergone profound changes since these stars were born. The fact that we can still recognize them as a group is truly amazing and a testament to the unprecedented data provided by Gaia,” Malhan stated.

The discovery was made possible through Gaia’s observations, which allowed researchers to determine the orbits, content, and composition of individual stars within the Milky Way. “Upon visualising the orbits of these stars, two new structures emerged, distinguished by their unique chemical composition. We named them Shakti and Shiva,” added Malhan.

A snake-like robot designed to look for life on Saturn’s moon

Posted by in categories: robotics/AI, space

A team of roboticists at California Institute of Technology’s Jet Propulsion Laboratory, working with a colleague from Carnegie Mellon University’s, Robotic Institute, has developed a snake-like robot to investigate the terrain on Enceladus, Saturn’s sixth-largest moon.

Research team establishes synthetic dimension dynamics to manipulate light

Posted by in categories: physics, space

In the realm of physics, synthetic dimensions (SDs) have emerged as one of the frontiers of active research, offering a pathway to explore phenomena in higher-dimensional spaces, beyond our conventional 3D geometrical space. The concept has garnered significant attention, especially in topological photonics, due to its potential to unlock rich physics inaccessible in traditional dimensions.

Have all 8 planets ever aligned?

Posted by in category: space

As the solar system’s planets rove around the sun, sometimes a few will appear to line up in the sky. But have all eight planets ever truly aligned?

The answer depends on how generous you are with the definition of “align” for the solar system’s planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Full-Scale Prototype Space Habitat Explodes Under Pressure

Posted by in categories: habitats, space

Private space company Sierra Space has blown up its first full-scale inflatable space habitat, dubbed the Large Integrated Flexible Environment (LIFE) — and it was all part of the plan.

The balloon-like contraption, which measured just over 20 feet tall, held a third of the volume of the International Space Station once fully inflated. During a recent test, engineers at the Colorado-based company kept pumping it with air, reaching a whopping 77 psi — well above NASA’s recommended level of 60.8 psi — before it exploded in spectacular fashion.

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.
