Scientists have detected subtle magnetic waves in the Sun, a discovery that could improve solar storm forecasting.
Scientists from the Tata Institute of Fundamental Research in Mumbai and New York University Abu Dhabi conducted the research.
Researchers have employed a technique to observe the movements within the Sun, known as helioseismology.
The team uses this method to examine the Sun’s surface and understand its internal movements. Similar to how earthquakes help us understand the Earth’s movements, this technique sheds light on the Sun’s dynamics.
The team analyzed over ten years of solar data gathered by the Solar Dynamics Observatory, a NASA-operated satellite.
They focused on data from the satellite’s Helioseismic and Magnetic Imager.
This instrument monitors oscillations and magnetic activity on the Sun’s surface.
After analyzing more than 5,000 days of solar data, scientists discovered two subtle waves moving through the Sun’s outer layers.
These waves connect to magneto-Rossby waves—large-scale patterns formed when the Sun’s rotation, fluid motion, and magnetic fields interact. This discovery provides new clues that help scientists predict dangerous solar storms more accurately.
The newly identified waves exist just below the Sun’s surface in a region known as the convection zone.
Hot plasma rises and falls in this region. These massive waves help transfer heat into space.
The observed wave patterns suggest a large doughnut-shaped magnetic field inside the Sun.
Scientists believe the Sun may contain a massive doughnut-shaped magnetic field hidden beneath its surface.
This magnetic field appears weak near the surface. However, deeper regions may contain much stronger magnetic forces.
Why Scientists Are Excited About the Sun’s Inner Magnetic Field?
Solar activity can directly affect life and technology on our planet.
Intense solar activity can trigger solar flares.
These flares send charged particles toward Earth.
These particles can disrupt satellites, communication systems, navigation, and power grids.
Scientists struggle to directly observe the solar cycle. This makes predicting solar activity difficult.
Recently detected magnetic waves may offer a new solution. They could help scientists monitor the Sun’s interior in real time.
This approach may also improve how scientists measure the Sun’s magnetic field.
Predicting Space Storms More Accurately
For years, scientists have predicted large-scale magnetic waves in the Sun.
However, detecting them has remained a major challenge.
New findings reveal hidden processes behind the Sun’s magnetism.
This breakthrough could help scientists predict dangerous solar storms more accurately.
