  Are we close to solve one of astrophysics greatest problems:
                     Coronal heating?

Kivonat:
Recent satellite (SOHO, TRACE, STEREO, Hinode, SDO) and ground-based 
(DST/ROSA, IBIS, CoMP, STT/CRISP) observations have provided plenty of clear 
evidence of waves and oscillations present in the solar atmosphere. The 
detection and analysis of these waves allows us to perform unprecedented 
sub-resolution solar magneto-seismology (SMS) of the solar plasma. First I 
will outline the latest developments in solar magnetohydrodynamic (MHD) wave 
theory focussing on linear waves and the SMS tool.
Next, I will concentrate on the role of the various MHD waves, and will 
discuss the latest status on detecting them. Within the framework of MHD I 
will discuss their photospheric origin and generation mechanism. I embark on 
showing how MHD waves sail throughout the chromosphere, transition region or 
even into the corona.
Finally, I will argue how the new observational data on MHD waves can be used 
towards solving the solar heating enigma.
