Researchers have identified a previously unknown type of large-scale magnetic wave deep inside the Sun [1].
These findings allow scientists to observe the hidden magnetic interior of the star, providing critical data on the processes that drive solar variability and space-weather effects on Earth [1, 2].
The Sun is composed of several distinct layers. At its center is the core, where temperatures reach approximately 15 million K [3]. Surrounding the core is the radiative zone, followed by the convection zone, the photosphere, the chromosphere, and the outermost corona [3].
While the standard solar model developed in the 1980s has successfully described these layers for decades [3], new data suggests the star is not static. Analysis of solar data spanning more than 40 years indicates that the Sun is subtly changing in ways that were not previously fully understood [4].
These observations include contributions from astrophysicists and solar researchers, including a team at NYU Abu Dhabi [1, 3]. The discovery of these deep-seated waves is particularly significant because direct measurements of the solar interior are impossible since light cannot escape those depths [1].
By studying these waves, scientists aim to refine their understanding of solar dynamics. The ability to track these internal shifts helps researchers predict how the Sun's magnetic activity influences the solar system [2, 4].
“Researchers have identified a previously unknown type of large-scale magnetic wave deep inside the Sun.”
The detection of these magnetic waves challenges the assumption of a static solar interior and suggests that the standard solar model from the 1980s requires updates. By bridging the gap between theoretical models and observable data, this research improves the ability to forecast space weather, which can disrupt satellite communications and power grids on Earth.
