| Scientists claim to have discovered a magnetic "solar heartbeat" in the Sun's deep interior, that generates energy which leads to solar flares and sunspots.
Researchers developed a new supercomputer simulation to probe the Sun's periodic magnetic field reversals. According to the model, every 40 years the Sun's zonal magnetic field bands switch their polarity.
Scientists say that cycle is about four times longer than the 11-year sunspot cycle that governs the level of solar activity, 'SPACE.com' reported. The new study, led by the University of Montreal's Paul Charbonneau, described that modelling the Sun has been a sticky problem for decades.
The first attempts in the 1980s captured only a rough approximation of the turbulence inside of the Sun. Turbulence happens at both large and small scales. When energy from turbulence dissipates, the turbulence flows into smaller and smaller whirlpool shapes, called vortices.
