Spicules are thin jet-like features on Sun which are believed to be the
possible candidates of transferring mass and energy from lower solar
atmosphere at a temperature of a few thousand degrees to higher up in
the hotter corona, which is at the temperature of millions of degrees.
This energy transfer takes place in form of waves and oscillations,
observed in the dynamics of these thin magnetic flux tubes (MFTs). The
2D image data taken from imaging-spectroscopy instruments at one of the
world's biggest ground-based solar telescope (Swedish Solar Telescope at
La Palma) were analyzed and the result is visualized as 3D motion of
the observed feature. The 3D visual shows swaying motion of the jet due
to magnetic field oscillations and changes in cross-sectional area due
to plasma perturbations.
