An oscillating magnetic field deep within the solar radiative region can significantly alter the helioseismic g-modes. The presence of density gradients along g-modes, can excite Alfvén waves ...

The Earth’s magnetic field is a shield that protects us from the sun’s harmful radiation. It’s a fascinating phenomenon that ...

Stunning imagery from outer space shows the power of the Sun, with a massive solar flare and coronal mass ejection erupting from the giant star’s surface, but space experts say there is no need ...

A vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, ...

is a non-invasive biomedical imaging technique that uses a strong oscillating magnetic field to induce endogenous atoms such as hydrogen, or exogenously added contrast agents, to emit radiowaves ...

3. Solar cycle: The sun has a magnetic field with north and south poles similar to a bar magnet. The magnetic field exists due to the constant movement of electrically charged particles within the Sun ...

Flower-shaped magnetic metamaterials are being used to boost the power of magnetic sensors and imaging tools by focusing magnetic fields with pinpoint precision. Credit: SciTechDaily.com Tiny magnetic ...

Mar. 17, 2025 — The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away ...
