Compression algorithms run on AI hardware to simulate nature’s most complex systems

Posted by in categories: climatology, information science, robotics/AI, space

High-performance computing (HPC) has become an essential tool for processing large datasets and simulating nature’s most complex systems. However, researchers face difficulties in developing more intensive models because Moore’s Law—which states that computational power doubles every two years—is slowing, and memory bandwidth still cannot keep up with it. But scientists can speed up simulations of complex systems by using compression algorithms running on AI hardware.

A team led by computer scientist Hatem Ltaief are tackling this problem head-on by employing designed for (AI) to help scientists make their code more efficient. In a paper published in the journal High Performance Computing, they now report making simulations up to 150 times faster in the diverse fields of climate modeling, astronomy, seismic imaging and wireless communications.

Previously, Ltaief and co-workers showed that many scientists were riding the wave of hardware development and “over-solving” their models, carrying out lots of unnecessary calculations.

First close-ups of a source of energetic particles expelled from the Sun

Posted by in categories: particle physics, space

Impulsive or Helium-3 enriched solar energetic particle (SEP) events, characterized by Helium-3 and ultra-heavy ion abundances, show high association with type III radio bursts. Minor (B-or C-class) GOES soft X-ray flares often accompany these events.

There are reports on such events measured in clusters from sub-flares in single active regions, where abundance showed significant variations. Imaging observations revealed that sources of these recurrent Helium-3 enriched are jets from solar plages (patches of scattered magnetic fields) or coronal hole edges.

From a distance of only half an astronomical unit (AU), or around 46.5 million miles, scientists from the Southwest Research Institute (SwRI) have made the first close-up observations of a source of energetic particles ejected from the Sun. ESA’s Solar Orbiter provided high-resolution images of the solar flare.

World’s First-Ever Space Hotel with Artificial Gravity to Be Ready by 2025

Posted by in category: space

Orbital Assembly Corporation, a California-based company, has announced plans to build the world’s first-ever space hotel with artificial gravity. The hotel, called Voyager Station, is set to be completed by 2025 and will offer guests an out-of-this-world experience like never before.

The Voyager Station will be assembled in low Earth orbit and will be able to accommodate up to 280 guests and 112 crew members at a time. The hotel will feature restaurants, bars, a gym, and other recreational facilities, all of which will be designed to offer an experience similar to that of a luxury cruise ship.

One of the most unique features of the hotel is its artificial gravity system, which will use centrifugal force to simulate the feeling of gravity. This will allow guests to move around the hotel as they would on Earth, which will make their stay much more comfortable and enjoyable.

Galaxy’s Hottest Exoplanet: Alien Atmosphere Holds Rare Terbium Surprise

Posted by in categories: space, sustainability

😗


The rare metal terbium has been found in an exoplanet.

An exoplanet (or extrasolar planet) is a planet that is located outside our Solar System, orbiting around a star other than the Sun. The first suspected scientific detection of an exoplanet occurred in 1988, with the first confirmation of detection coming in 1992.

Elon Musk wants to develop TruthGPT, ‘a maximum truth-seeking AI’

Posted by in categories: Elon Musk, robotics/AI, space

On Tuesday, Elon Musk said in an interview with Fox News’ Tucker Carlson that he wants to develop his own chatbot called TruthGPT, which will be “a maximum truth-seeking AI” — whatever that means.

The Twitter owner said that he wants to create a third option to OpenAI and Google with an aim to “create more good than harm.”

“I’m going to start something which you call TruthGPT or a maximum truth-seeking AI that tries to understand the nature of the universe. And I think this might be the best path to safety in the sense that an AI that cares about understanding the universe is unlikely to annihilate humans because we are an interesting part of the universe,” Musk said during the Fox & Friends show.

Astronomers just saw a star eat a planet—an astrophysicist on the team explains the first-of-its-kind discovery

Posted by in categories: computing, space

For the first time, astronomers have captured images that show a star consuming one of its planets. The star, named ZTF SLRN-2020, is located in the Milky Way galaxy, in the constellation Aquila. As the star swallowed its planet, the star brightened to 100 times its normal level, allowing the 26-person team of astronomers I worked with to detect this event as it happened.

I am a theoretical astrophysicist, and I developed the computer models that our team uses to interpret the data we collect from telescopes. Although we only see the effects on the star, not the planet directly, our team is confident that the event we witnessed was a star swallowing its planet. Witnessing such an event for the first time has confirmed the long-standing assumption that stars swallow their and has illuminated how this fascinating process plays out.
