Cannibal Solar Storm May Trigger Auroras as Powerful Geomagnetic Storm to Hit Earth Soon
Between Sept. 1–2, Earth will be struck by a powerful geomagnetic storm caused by a rare “cannibal” solar eruption. The event formed when a fast coronal mass ejection (CME) overtook and consumed an earlier one, creating a stronger, chaotic cloud. As this storm interacts with Earth’s magnetic field, it may produce vivid auroras visible far b...

Researchers Discover New Plasma Wave in Jupiter’s Auroral Skies
Scientists at the University of Minnesota Twin Cities have detected a new plasma wave in Jupiter’s aurora using NASA’s Juno spacecraft. The finding, published in Physical Review Letters, reveals how Jupiter’s magnetic field shapes auroral activity differently from Earth. The study opens new directions for understanding planetary auroras and m...

Metamaterial Breaks Thermal Symmetry, Enables One-Way Heat Emission
Scientists have created a groundbreaking metamaterial that breaks Kirchhoff’s law by emitting 43% more mid-infrared radiation in one direction than it absorbs. Built from layered InGaAs and tested at 512°F with a 5T magnetic field, the structure exhibits record thermal nonreciprocity. This breakthrough enables controlled one-way heat flow, a ste...

Magnetic Fields Could Significantly Influence Oscillations in Merging Neutron Stars, Study Finds
Magnetic fields may play a bigger role in neutron star mergers than previously thought. A new study using advanced simulations shows that these fields can shift or suppress oscillation frequencies, altering gravitational wave signatures. This discovery could change how astronomers decode post-merger signals and refine models of neutron star interio...

New Polar Cataclysmic Variable Identified by Astronomers: What You Need to Know
Astronomers have detected ZTF J0112+5827, a newly identified polar cataclysmic variable. This binary system, composed of a white dwarf and a low-mass donor star, features an 80.9-minute orbital period and a strong magnetic field of 38.7 MG. It lacks an accretion disk, with emissions mainly from its accretion stream and magnetic field lines. The sys...
