Britain 3D MT Model Reveals Hidden Subsurface Geophysics
New 3D Electrical Map Sheds Light on Britain’s Deep Structure A milestone in terrestrial geophysics arrives with Montiel-Álvarez and colleagues’ first 3D electrical resistivity model of Britain. Built from long-period magnetotelluric (MT) data collected across the island, the model—named BERM-2024—provides a high-resolution view of how electrically conductive and resistive rocks are arranged beneath Britain’s surface.…

New 3D Model Reveals Britain’s Subsurface Geophysical Structures
Unveiling Britain’s Hidden Architecture Magnetotelluric (MT) surveys, which measure natural electric and magnetic field variations at the Earth’s surface, offer a window into the subsurface by mapping electrical resistivity. Changes in resistivity help scientists identify geologic features such as igneous intrusions, sedimentary basins, and variations in crustal composition. A new 3D resistivity model, based on…

New 3D Model Reveals Geophysical Structures Beneath Britain
Unveiling Britain’s Subsurface with 3D Magnetotellurics Researchers have produced the first comprehensive 3D electrical resistivity model of Britain, offering a new view into the country’s hidden geophysical structures. The model, called BERM-2024, is built from long-period magnetotelluric (MT) data that track variations in electric and magnetic fields at Earth’s surface. By interpreting how easily electrical…

Beyond Our Orbit: The Strangest Planets We Have Uncovered
Beyond Our Orbit: A tour of the cosmos’ most perplexing planets Planet hunting has yielded a catalog bursting with surprises. From pressure-made ice to diamond cores, the universe keeps offering worlds that defy our Earth-centric intuition. Below is a curated look at some of the strangest planets we have uncovered so far, each illuminating a…

Solar Sail Probes to Detect Space Tornadoes: A New Era in Space Weather Warnings
Introduction: A New Approach to Space Weather Warnings Scientists are rethinking how we monitor space weather by looking beyond the Sun itself. A recent study suggests that a constellation of spacecraft — including a solar sailer riding on sunlight — could detect tornado-like twists in the solar wind much earlier than current single-spacecraft systems allow.…

Solar sail probe could detect space tornadoes earlier
New simulations reveal hidden space weather threats Researchers simulate a vast cloud of solar plasma to understand how small, tornado-like features in the solar wind—known as flux ropes—form and evolve. These mid-sized structures can spin up from coronal mass ejections as they plow through slower solar wind, potentially generating strong magnetic fields that trigger geomagnetic…

Near-Miss 9.8-Foot Asteroid 2025 TF: A Quiet Reminder of Planetary Defense
Introduction to a Narrow Escape On October 1, a tiny yet attention-grabbing object—a 9.8-foot (three-meter) asteroid named 2025 TF—passed closer to Earth than the International Space Station, flying roughly 265 miles (428 kilometers) above the planet. The encounter happened over Antarctica and went undetected for hours, highlighting both the ingenuity of current asteroid tracking and…

We Ain’t Seen Nothing Yet: Is There Truly Empty Space in Our Cosmos?
Is There Any Truly Empty Space in Our Cosmos? We often imagine space as a vast, silent void. But as our closest solar neighborhood and beyond reveal, empty space is more of a scientific myth than a naked truth. From the International Space Station to the far reaches of interstellar space, the cosmos is filled…

We Ain’t Seen Nothing Yet: The Real Empty Space of Our Solar System
The Myth of Cosmic Vacuum When people imagine space, they often picture a perfect, absolute void. But in truth, the space between worlds is crowded with a surprising mix of matter and energy. From our own backyard around the International Space Station to the vast stretches between stars, “empty” space is a relative term that…

Solar Storms and Solar Wind: How Particles from the Sun Interact with Earth
What are solar wind and solar storms? Every day, Earth experiences weather—wind, rain, and storms. But there’s also weather in space, driven by the Sun. Two key ideas scientists talk about are the solar wind and solar storms. The solar wind is a continuous stream of charged particles, mainly protons and electrons, that blow outward…
