A new type of high-frequency acoustic wave discovered propagating on the Sun seems to be defying expectations.
The waves appear on the surface of the Sun as a pattern of swirling vortices, moving against the Sun’s rotation. The problem is that these high-frequency retrograde vorticity waves seem to be moving three times faster than predicted by theory – and solar physicists have been unable to determine why.
The discovery, they say, suggests that there is new solar physics to be uncovered ... Read even more
