Top Headlines

 

Astronomers have long relied on supercomputers to simulate the immense structure of the Universe, but a new tool called Effort.jl is changing that. By mimicking the behavior of complex cosmological models, this emulator delivers results with the ...
Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold dark matter, providing long-sought answers about ...
A new AI model from NYU Abu Dhabi predicts solar wind days in advance with far greater accuracy than existing methods. By analyzing ultraviolet solar images, it could help protect satellites, navigation systems, and power grids from disruptive space ...
The booming space industry has filled the skies with rockets and satellites, but this rapid expansion comes with a hidden danger: slowing the recovery of the ozone layer. Rocket launches and burning space debris release chlorine, soot, and metals ...
NASA’s Magnetospheric Multiscale Mission has uncovered surprising behavior of pickup ions drifting through the solar wind near Earth. These particles, once thought to be minor players, appear capable of generating waves and influencing how the ...
Physicists have unveiled a new superconducting detector sensitive enough to hunt dark matter particles smaller than electrons. By capturing faint photon signals, the device pushes the search into uncharted ...
Scientists caution that asteroid deflection must be precise, as striking the wrong spot risks sending it through a gravitational keyhole that sets up a future collision with Earth. Using lessons from NASA’s DART mission, researchers are developing ...
Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the ...
Astronomers using AI have captured a once-in-a-lifetime cosmic event: a massive star’s violent death triggered by its black hole companion. The explosion, known as SN 2023zkd, not only produced a brilliant supernova but also shocked scientists by ...
NASA and ISRO s NISAR satellite has just reached a major milestone: the successful deployment of its enormous 39-foot antenna reflector in orbit. Folded up like an umbrella during launch, the reflector is now fully extended and ready to support ...
With its two tiny CubeSats, NASA’s PREFIRE mission is capturing invisible heat escaping from Earth, offering clues to how ice, clouds, and storms influence the climate system. The insights could lead to better weather forecasts and a deeper ...
Rising CO₂ levels will make the upper atmosphere colder and thinner, altering how geomagnetic storms impact satellites. Future storms could cause sharper density spikes despite lower overall density, increasing drag-related ...

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, ...

Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered ...

Jezero Crater’s rocks reveal three stages of water activity, shifting from hostile acidic fluids to more life-friendly alkaline ones. Perseverance’s discoveries guide future sampling and ...

Astronomers have detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf star, offering the clearest evidence yet that icy, life-delivering ...

A strange “Einstein Cross” with an extra, impossible fifth image has revealed the hidden presence of a massive dark matter halo. An international team of astronomers, including Rutgers ...

Astronomers using the James Webb Space Telescope have uncovered mysterious “little red dots” that may not be galaxies at all, but a whole new type of object: black hole stars. These fiery ...

Billions of years ago, Mars may not have been the frozen desert we see today. New simulations suggest that volcanic eruptions pumped out reactive sulfur gases, creating greenhouse effects strong ...

NASA’s Perseverance rover has delivered its most compelling clue yet in the search for life on Mars. A rock sample called “Sapphire Canyon,” taken from the Bright Angel formation in Jezero ...

For centuries, scientists have puzzled over globular clusters, the dense star systems that orbit galaxies without dark matter. Using ultra-detailed simulations, researchers recreated their origins ...

Mars’ Jezero Crater holds signs of ancient water and strange mineral reactions, some linked with organic compounds. With Perseverance’s samples and AI-refined mineral maps, scientists are closing ...

Gravitational-wave astronomy has exploded since 2015, capturing hundreds of black hole and neutron star collisions. With ever-clearer signals, researchers are testing Einstein’s relativity and ...

Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of ...

Behind the dusty clouds of the Cigar Galaxy lies a dazzling powerhouse of star formation, where stars are being born ten times faster than in the Milky Way. Astronomers using the Hubble Space ...

Astronomers have uncovered the violent secret of V Sagittae, a white dwarf star consuming its companion in a spectacular feeding frenzy. This cosmic dance not only makes the system burn with unusual ...

Astronomers studying an oddball brown dwarf called “The Accident” have finally spotted silane, a long-predicted silicon molecule missing from Jupiter and Saturn’s skies. Its ancient, ...

Saturn’s icy moon Enceladus has long fascinated scientists with its spectacular water plumes, which NASA’s Cassini spacecraft once revealed to contain organic molecules. Many hoped these ...

NASA’s Perseverance rover has discovered mudstones in Mars’ Jezero Crater that contain organic carbon and unusual textures hinting at possible biosignatures. These findings suggest that ancient ...

Physicists at the University of Colorado Boulder have created the first time crystal that humans can actually see, using liquid crystals that swirl into never-ending patterns when illuminated by ...

Scientists from the University of St Andrews have discovered that ions in solar flares can reach scorching temperatures more than 60 million degrees—6.5 times hotter than previously believed. This ...

Hubble’s latest image captures a glittering star cluster inside the Large Magellanic Cloud, a dwarf galaxy about 160,000 light-years from Earth. This region, known as N11, is one of the galaxy’s ...
