Gaia maps largest ever collection of quasars in space and time

Posted by in categories: cosmology, mapping

Astronomers have created the largest yet cosmic 3D map of quasars: bright and active centres of galaxies powered by supermassive black holes. This map shows the location of about 1.3 million quasars in space and time, with the furthest shining bright when the Universe was only 1.5 billion years old.

The new map has been made with data from ESA’s Gaia space telescope. While Gaia’s main objective is to map the stars in our own galaxy, in the process of scanning the sky it also spots objects outside the Milky Way, such as quasars and other galaxies.

The graphic representation of the map (bottom right on the infographic) shows us the location of quasars from our vantage point, the centre of the sphere. The regions empty of quasars are where the disc of our galaxy blocks our view.

Larry Ellison and Elon Musk teaming up to bring AI to farming

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

Elon Musk’s SpaceX is teaming up with Larry Ellison’s Oracle to help farms plan and predict their agricultural output using an AI tool.

Larry Ellison said on Oracle’s earnings call on Monday that it’s collaborating with Musk and SpaceX to create the AI-powered mapping application for governments. The tool creates a map of a country’s farms and shows what each of them is growing.

The Oracle executive chairman said the tool could help farms assess the steps needed to increase their output, and whether fields had enough water and nitrogen.

Scientists Intrigued by Jet Inside Jupiter

Posted by in categories: mapping, space

Jupiter is iconic, with its swirls of water and ammonia vapor that characterize its outer surface and its distinctive Giant Red Spot, a gigantic storm raging across its face.

But its mysteries abound — such as Jupiter’s strange and asymmetrical magnetic field, which has a strong area of magnetism in its equator called the “Great Blue Spot” — blue because that’s how it’s color-coded in maps tracing the magnetic field.

In an effort to understand the planet’s magnetic field better, a team of American scientists from Harvard University, the California Institute of Technology, NASA and the Southwest Research Institute in San Antonio, Texas studied an atmospheric jet — a high speed current in the gas giant’s atmosphere — in the Great Blue Spot. Their finding? It’s a dynamic system that fluctuates every four years or so.

Fresh X-Rays Reveal a Universe as Clumpy as Cosmology Predicts

Posted by in categories: cosmology, mapping

A recent study of thousands of galaxy clusters may ease a debate about the clumpiness of cosmic matter and reinforce the standard model of cosmology.


By mapping the largest structures in the universe in X-rays, cosmologists have found striking agreement with their standard theoretical model of how the universe evolves.

Researchers reach new AI benchmark for computer graphics

Posted by in categories: climatology, mapping, robotics/AI

Computer graphic simulations can represent natural phenomena such as tornados, underwater, vortices, and liquid foams more accurately thanks to an advancement in creating artificial intelligence (AI) neural networks.

Working with a multi-institutional team of researchers, Georgia Tech Assistant Professor Bo Zhu combined computer graphic simulations with machine learning models to create enhanced simulations of known phenomena. The new benchmark could lead to researchers constructing representations of other phenomena that have yet to be simulated.

Zhu co-authored the paper “Fluid Simulation on Neural Flow Maps.” The Association for Computing Machinery’s Special Interest Group in Computer Graphics and Interactive Technology (SIGGRAPH) gave it a best paper award in December at the SIGGRAPH Asia conference in Sydney, Australia.

Space observatory in Chile unveils new maps of the universe

Posted by in categories: cosmology, mapping, physics

We are always making strides to unravel the mysteries of our universe. Now, a small observatory nestled in the Andes mountains of northern Chile has provided a snapshot of the cosmos in space. This one is clearer than we imagined.

The U.S. National Science Foundation Cosmology Large Angular Scale Surveyor (CLASS), spearheaded by astrophysicists from Johns Hopkins University, mapped a whopping 75 percent of the sky.

AI Is Everywhere—Including Countless Applications You’ve Likely Never Heard Of

Posted by in categories: information science, mapping, robotics/AI, transportation

One major area of our lives that uses largely “hidden” AI is transportation. Millions of flights and train trips are coordinated by AI all over the world. These AI systems are meant to optimize schedules to reduce costs and maximize efficiency.

Artificial intelligence can also manage real-time road traffic by analyzing traffic patterns, volume and other factors, and then adjusting traffic lights and signals accordingly. Navigation apps like Google Maps also use AI optimization algorithms to find the best path in their navigation systems.

AI is also present in various everyday items. Robot vacuum cleaners use AI software to process all their sensor inputs and deftly navigate our homes.

Beyond Binary: The Light-Driven Computing Revolution

Posted by in categories: computing, mapping

Researchers develop a computer from an array of VCSELs with optical feedback.

In our data-driven era, solving complex problems efficiently is crucial. However, traditional computers often struggle with this task when dealing with a large number of interacting variables, leading to inefficiencies such as the von Neumann bottleneck. A new type of collective state computing has emerged to address this issue by mapping these optimization problems onto something called the Ising problem in magnetism.

Understanding the Ising Problem.

Submolecular-scale control of phototautomerization

Posted by in category: mapping

Weak laser light confined at the apex of a scanning tunnelling microscope tip can drive the tautomerization of a free-base phthalocyanine with atomic-scale precision. The combination of tip-enhanced photoluminescence spectroscopy and hyperspectral mapping paired with theoretical modelling then unravel an excited-state mediated reaction.
